This work presents simulation results for the production of hydrogen by the rich combustion of heavy fuel oil in a dual zone packed bed reactor. The first zone provides catalytic-thermal cracking of the fuel and is followed by a second zone for partial oxidation reforming of the cracked products. The kinetic model for the heavy fuel oil reactions in the catalytic zone uses decalin as a model compound. The partial oxidation reforming zone uses model compounds for the product groups formed from decalin cracking, and uncracked decalin. The hybrid reactor model is compared to results from a model of an inert (non-catalytic) porous media reactor. The work considers equivalence ratios from 1 to 2, filtration velocities between 15.0 and 65.5 cm/s, heat loss from 10 to 108% and particle diameter between 3 and 7 mm, and evaluates their effect on conversion. The simulations with the hybrid reactor model, in slightly rich conditions (equivalence ratio = 1.3) and constant filtration velocity of 19.3 cm/s deliver maximum hydrogen production for an optimal length of the intermediate zone. Considering this optimization: the total energy conversion efficiencies improve with the increase of the equivalence ratio due to the presence of hydrocarbon species generated by the cracking process. It is observed that the hybrid reactor model makes a better use of vaporized fuel, compared to a model for an inert packed bed reactor, when the deposits of carbonaceous material in the latter exceed 7.4%.

这项工作提出了在双区填充床反应器中重质燃料浓燃烧产生氢的模拟结果。第一区域提供燃料的催化热裂化，然后是第二区域，用于对裂化产物进行部分氧化重整。催化区中重质燃料油反应的动力学模型使用十氢化萘作为模型化合物。部分氧化重整区将模型化合物用于由十氢化萘裂解和未裂解的十氢化萘形成的产物组。将混合反应器模型与惰性（非催化）多孔介质反应器模型的结果进行比较。该工作考虑当量比为1至2，过滤速度为15.0至65.5 cm / s，热损失为10至108％，粒径为3至7 mm，并评估其对转化率的影响。用混合反应器模型进行的模拟在稍富的条件下（当量比= 1.3）和恒定的19.3 cm / s的过滤速度为最佳中间区域长度提供了最大的产氢量。考虑这种优化：由于存在裂化过程中产生的烃类，总的能量转换效率随着当量比的增加而提高。可以看出，当惰性材料中的碳质沉积物超过7.4％时，与惰性填充床反应器相比，混合反应器模型可以更好地利用汽化燃料。3 cm / s可提供最佳的中间区域长度最大的产氢量。考虑这种优化：由于存在裂化过程中产生的烃类，总的能量转换效率随着当量比的增加而提高。可以看出，当惰性材料中的碳质沉积物超过7.4％时，与惰性填充床反应器相比，混合反应器模型可以更好地利用汽化燃料。3 cm / s可提供最佳的中间区域长度最大的产氢量。考虑这种优化：由于存在裂化过程中产生的烃类，总的能量转换效率随着当量比的增加而提高。可以看出，当惰性材料中的碳质沉积物超过7.4％时，与惰性填充床反应器相比，混合反应器模型可以更好地利用汽化燃料。
