<p><strong>Design principles a</strong> <strong>heterogeneously catalyzed autothermal reactor with enhanced heat and mass transfer for hydrogen production</strong></p> <p>Junjie Chen</p> <p>Department of Energy and Power Engineering, School of Mechanical and Power Engineering, Henan Polytechnic University, 2000 Century Avenue, Jiaozuo, Henan, 454000, P.R. China</p> <p>Contributor: Junjie Chen, ORCID: 0000-0001-5055-4309, E-mail address: komcjj@gmail.com</p> <p> </p> <p>Catalysis, in chemistry, is the modification of the rate of a chemical reaction, usually an acceleration, by addition of a substance not consumed during the reaction. The rates of chemical reactions, that is, the velocities at which they occur, depend upon a number of factors, including the chemical nature of the reacting species and the external conditions to which they are exposed. A particular phenomenon associated with the rates of chemical reactions that is of great theoretical and practical interest is catalysis, the acceleration of chemical reactions by substances not consumed in the reactions themselves, substances known as catalysts. The study of catalysis is of interest theoretically because of what it reveals about the fundamental nature of chemical reactions; in practice, the study of catalysis is important because many industrial processes depend upon catalysts for their success. In a catalyzed reaction, the catalyst generally enters into chemical combination with the reactants but is ultimately regenerated, so the amount of catalyst remains unchanged. Since the catalyst is not consumed, each catalyst molecule may induce the transformation of many molecules of reactants. For an active catalyst, the number of molecules transformed per minute by one molecule of catalyst may be as large as several million. Where a given substance or a combination of substances undergoes two or more simultaneous reactions that yield different products, the distribution of products may be influenced by the use of a catalyst that selectively accelerates one reaction relative to the other(s). By choosing the appropriate catalyst, a particular reaction can be made to occur to the extent of practically excluding another. Many important applications of catalysis are based on selectivity of this kind.</p> <p>Streamwise distance (millimeters), Reforming channel centerline temperature (degrees kelvin)</p> <p>0 373</p> <p>0.00025 373.048742</p> <p>0.0005 373.2382942</p> <p>0.00075 373.7354626</p> <p>0.001 374.7081362</p> <p>0.00125 376.2548823</p> <p>0.0015 378.3951976</p> <p>0.00175 381.0814232</p> <p>0.002 384.2247405</p> <p>0.00225 387.7222496</p> <p>0.0025 391.465635</p> <p>0.00275 395.3617454</p> <p>0.003 399.3347598</p> <p>0.00325 403.3218552</p> <p>0.0035 407.2775391</p> <p>0.00375 411.1628179</p> <p>0.004 414.9538621</p> <p>0.00425 418.6311751</p> <p>0.0045 422.1828419</p> <p>0.00475 425.6012807</p> <p>0.005 428.8821587</p> <p>0.00525 432.025476</p> <p>0.0055 435.0312325</p> <p>0.00575 437.9015946</p> <p>0.006 440.6398117</p> <p>0.00625 443.2502165</p> <p>0.0065 445.7371415</p> <p>0.00675 448.1049195</p> <p>0.007 450.3600492</p> <p>0.00725 452.5057803</p> <p>0.0075 454.5475284</p> <p>0.00775 456.4896262</p> <p>0.008 458.3374895</p> <p>0.00825 460.0954509</p> <p>0.0085 461.7689261</p> <p>0.00875 463.3600816</p> <p>0.009 464.874333</p> <p>0.00925 466.3149298</p> <p>0.0095 467.6862047</p> <p>0.00975 468.9924902</p> <p>0.01 470.2348696</p> <p>0.01025 471.4176754</p> <p>0.0105 472.5441571</p> <p>0.01075 473.6175642</p> <p>0.011 474.6389798</p> <p>0.01125 475.6138198</p> <p>0.0115 476.5431672</p> <p>0.01175 477.4302716</p> <p>0.012 478.276216</p> <p>0.01225 479.0831669</p> <p>0.0125 479.8543736</p> <p>0.01275 480.5909193</p> <p>0.013 481.2938872</p> <p>0.01325 481.9665268</p> <p>0.0135 482.6099212</p> <p>0.01375 483.2251535</p> <p>0.014 483.8143901</p> <p>0.01425 484.377631</p> <p>0.0145 484.9170424</p> <p>0.01475 485.4347907</p> <p>0.015 485.930876</p> <p>0.01525 486.4063812</p> <p>0.0155 486.8623897</p> <p>0.01575 487.3010677</p> <p>0.016 487.721332</p> <p>0.01625 488.1264322</p> <p>0.0165 488.515285</p> <p>0.01675 488.8889736</p> <p>0.017 489.2496644</p> <p>0.01725 489.5962742</p> <p>0.0175 489.9309692</p> <p>0.01775 490.2526664</p> <p>0.018 490.5646152</p> <p>0.01825 490.8646493</p> <p>0.0185 491.1560181</p> <p>0.01875 491.4365554</p> <p>0.019 491.7073443</p> <p>0.01925 491.970551</p> <p>0.0195 492.2250926</p> <p>0.01975 492.472052</p> <p>0.02 492.7114294</p> <p>0.02025 492.9432247</p> <p>0.0205 493.1696042</p> <p>0.02075 493.3884016</p> <p>0.021 493.6017832</p> <p>0.02125 493.8086659</p> <p>0.0215 494.0101329</p> <p>0.02175 494.2072672</p> <p>0.022 494.3989857</p> <p>0.02225 494.5863716</p> <p>0.0225 494.7683417</p> <p>0.02275 494.9470624</p> <p>0.023 495.1214504</p> <p>0.02325 495.2915058</p> <p>0.0235 495.4583118</p> <p>0.02375 495.6218682</p> <p>0.024 495.7810921</p> <p>0.02425 495.9381497</p> <p>0.0245 496.0919577</p> <p>0.02475 496.2425163</p> <p>0.025 496.3898255</p> <p>0.02525 496.5360515</p> <p>0.0255 496.679028</p> <p>0.02575 496.8187551</p> <p>0.026 496.9563158</p> <p>0.02625 497.0927934</p> <p>0.0265 497.2260215</p> <p>0.02675 497.3570834</p> <p>0.027 497.4859789</p> <p>0.02725 497.6137912</p> <p>0.0275 497.7383541</p> <p>0.02775 497.8618338</p> <p>0.028 497.9831472</p> <p>0.02825 498.1033775</p> <p>0.0285 498.2203583</p> <p>0.02875 498.3362559</p> <p>0.029 498.4499873</p> <p>0.02925 498.5637186</p> <p>0.0295 498.6666184</p> <p>0.02975 498.796597</p> <p>0.03 498.88</p> <p>Contributor: Junjie Chen, ORCID: 0000-0001-5055-4309, E-mail address: komcjj@gmail.com, Department of Energy and Power Engineering, School of Mechanical and Power Engineering, Henan Polytechnic University, 2000 Century Avenue, Jiaozuo, Henan, 454000, P.R.

Design principles an autothermal reactor with enhanced mass transfer for hydrogen production
<p><strong>Design principles an autothermal reactor with enhanced mass transfer for hydrogen production</strong></p> <p>Junjie Chen</p> <p>Department of Energy and Power Engineering, School of Mechanical and Power Engineering, Henan Polytechnic University, 2000 Century Avenue, Jiaozuo, Henan, 454000, P.R. China</p> <p>Contributor: Junjie Chen, ORCID: 0000-0001-5055-4309, E-mail address: komcjj@gmail.com</p> <p> </p> <p>Chemical engineers are employed in the design and development of both processes and plant items. In each case, data and predictions often have to be obtained or confirmed with pilot experiments. Plant operation and control is increasingly the sphere of the chemical engineer rather than the chemist. Chemical engineering provides an ideal background for the economic evaluation of new projects and, in the plant construction sector, for marketing. The fundamental principles of chemical engineering underlie the operation of processes extending well beyond the boundaries of the chemical industry, and chemical engineers are employed in a range of operations outside traditional areas. Plastics, polymers, and synthetic fibres involve chemical-reaction engineering problems in their manufacture, with fluid flow and heat transfer considerations dominating their fabrication. The dyeing of a fibre is a mass-transfer problem. Pulp manufacture involve considerations of fluid flow and heat transfer. The nuclear industry makes similar demands on the chemical engineer, particularly for fuel manufacture and reprocessing. Chemical engineers are involved in many sectors of the metals processing industry, which extends from steel manufacture to separation of rare metals.</p> <p>Streamwise distance (millimeters), Reforming channel centerline temperature (degrees kelvin)</p> <p>0 373.004</p> <p>0.00025 373.059</p> <p>0.0005 373.261</p> <p>0.00075 373.771</p> <p>0.001 374.741</p> <p>0.00125 376.228</p> <p>0.0015 378.219</p> <p>0.00175 380.651</p> <p>0.002 383.434</p> <p>0.00225 386.47</p> <p>0.0025 389.674</p> <p>0.00275 393.013</p> <p>0.003 396.47</p> <p>0.00325 400.02</p> <p>0.0035 403.634</p> <p>0.00375 407.275</p> <p>0.004 410.898</p> <p>0.00425 414.453</p> <p>0.0045 417.9</p> <p>0.00475 421.231</p> <p>0.005 424.454</p> <p>0.00525 427.574</p> <p>0.0055 430.596</p> <p>0.00575 433.522</p> <p>0.006 436.342</p> <p>0.00625 439.041</p> <p>0.0065 441.606</p> <p>0.00675 444.041</p> <p>0.007 446.359</p> <p>0.00725 448.572</p> <p>0.0075 450.693</p> <p>0.00775 452.727</p> <p>0.008 454.676</p> <p>0.00825 456.532</p> <p>0.0085 458.289</p> <p>0.00875 459.952</p> <p>0.009 461.531</p> <p>0.00925 463.036</p> <p>0.0095 464.477</p> <p>0.00975 465.858</p> <p>0.01 467.18</p> <p>0.01025 468.441</p> <p>0.0105 469.635</p> <p>0.01075 470.767</p> <p>0.011 471.843</p> <p>0.01125 472.873</p> <p>0.0115 473.859</p> <p>0.01175 474.805</p> <p>0.012 475.713</p> <p>0.01225 476.579</p> <p>0.0125 477.403</p> <p>0.01275 478.186</p> <p>0.013 478.933</p> <p>0.01325 479.649</p> <p>0.0135 480.337</p> <p>0.01375 480.998</p> <p>0.014 481.634</p> <p>0.01425 482.243</p> <p>0.0145 482.823</p> <p>0.01475 483.376</p> <p>0.015 483.906</p> <p>0.01525 484.415</p> <p>0.0155 484.905</p> <p>0.01575 485.379</p> <p>0.016 485.835</p> <p>0.01625 486.273</p> <p>0.0165 486.692</p> <p>0.01675 487.093</p> <p>0.017 487.477</p> <p>0.01725 487.848</p> <p>0.0175 488.206</p> <p>0.01775 488.553</p> <p>0.018 488.889</p> <p>0.01825 489.212</p> <p>0.0185 489.522</p> <p>0.01875 489.82</p> <p>0.019 490.106</p> <p>0.01925 490.383</p> <p>0.0195 490.651</p> <p>0.01975 490.913</p> <p>0.02 491.168</p> <p>0.02025 491.413</p> <p>0.0205 491.648</p> <p>0.02075 491.875</p> <p>0.021 492.093</p> <p>0.02125 492.306</p> <p>0.0215 492.513</p> <p>0.02175 492.716</p> <p>0.022 492.915</p> <p>0.02225 493.106</p> <p>0.0225 493.291</p> <p>0.02275 493.469</p> <p>0.023 493.642</p> <p>0.02325 493.811</p> <p>0.0235 493.977</p> <p>0.02375 494.141</p> <p>0.024 494.301</p> <p>0.02425 494.456</p> <p>0.0245 494.607</p> <p>0.02475 494.753</p> <p>0.025 494.895</p> <p>0.02525 495.036</p> <p>0.0255 495.174</p> <p>0.02575 495.311</p> <p>0.026 495.446</p> <p>0.02625 495.578</p> <p>0.0265 495.706</p> <p>0.02675 495.831</p> <p>0.027 495.953</p> <p>0.02725 496.074</p> <p>0.0275 496.195</p> <p>0.02775 496.315</p> <p>0.028 496.433</p> <p>0.02825 496.549</p> <p>0.0285 496.661</p> <p>0.02875 496.772</p> <p>0.029 496.881</p> <p>0.02925 496.99</p> <p>0.0295 497.092</p> <p>0.02975 497.232</p> <p>0.03 497.324</p> <p>Contributor: Junjie Chen, ORCID: 0000-0001-5055-4309, E-mail address: komcjj@gmail.com, Department of Energy and Power Engineering, School of Mechanical and Power Engineering, Henan Polytechnic University, 2000 Century Avenue, Jiaozuo, Henan, 454000, P.R.
