丙烷自热重整制氢

HYDROGEN PRODUCING FROM PROPANE AUTOTHERMAL REFORMING

以丙烷为主要成分的液化石油气(LPG)是一种有希望作为燃料电池车车载制氢系统的燃料。本文利用SIMSCI公司的PRO/Ⅱ软件对丙烷的自热重整制氢过程进行了研究,结果显示,空气比率是一个重要的参数,会对热效率产生敏感的影响。对于一套其他参数,存在一个最优的空气比率值,而且随着操作压力增加和操作温度的降低而降低。虽然汽碳比率对热效率影响不大,但是对产物气中氢气和一氧化碳的含量影响较大。通过对操作条件的分析,绘成了不同操作条件下的最优热效率图,可对重整系统的整合分析起到指导作用。

Liquefied petroleum gas (LPG), with propane as the main component, is a promising fuel for on-board hydrogen producing system for fuel cell vehicles. In this work, hydrogen producing with propane autothermal reforming (ATR) is studied with the aid of PRO/Ⅱ^(?) from SIMSCI. Results indicate that air stoichiometry λ_(air) is an important variable and will impact thermal efficiency sensibly, and that there will be an optimum value for each set of other parameters. Optimum thermal efficiency decrease with the i...
