The production of hydrogen from glycerol steam reforming has been studied in several reactors. In conventional reactors the catalyst is deactivated by coke: in fixed bed reactors plugging was observed if a low steam/glycerol ratio was employed, while in fluidized bed reactors it was possible to operate for a longer time-on-stream. The use of a two-zone fluidized bed reactor is studied in this work, as a method to counteract the problem of catalyst deactivation by coke. The glycerol reforming takes place in the upper part of this reactor while the catalyst is simultaneously regenerated in the lower part, where a stream of a regenerating gas is introduced. It has been found that CO₂, O₂ or H₂O can act as regenerating gas in a two-zone-fluidized bed reactor, allowing steady state operation at a water:glycerol molar ratio as low as 1.25. The effect of the operating conditions has been studied and the yield to the main products was compared with the calculated values assuming thermodynamic equilibrium.

已经在几个反应器中研究了由甘油蒸汽重整生产氢气。在常规反应器中，催化剂通过焦炭失活：在固定床反应器中，如果采用较低的蒸汽/甘油比，则会发生堵塞，而在流化床反应器中，则可能需要更长的运行时间。在这项工作中，研究了使用两区流化床反应器，以此作为解决因焦炭而使催化剂失活的方法。甘油重整在该反应器的上部进行，同时催化剂在下部同时再生，在下部引入再生气流。已经发现CO ₂，O ₂或H ₂O可以在两区流化床反应器中充当再生气体，允许在水与甘油的摩尔比低至1.25的情况下稳定运行。研究了操作条件的影响，并在假定热力学平衡的情况下将主要产品的收率与计算值进行了比较。
