Abstract

将废气重整再循环（REGR）技术应用于船用LNG发动机，可有效回收废气能量、改善发动机缸内燃烧、降低污染物排放。然而，发动机废气工况复杂、受到多重边界限制，对废气-天然气重整反应机制以及高活性、高稳定性催化剂的应用尚不清晰，限制了对重整过程的精确调控。本文首先利用CFD介观数值模拟方法探究了催化剂载体形貌对流动传热特性的影响；基于此制备优化了Ni-Pt/Al2O3催化剂，分析了反应过程中热应力变化、载体结构强度、反应进料比对催化剂结构稳定性的影响；探究了废气的低温、高稀释和复杂边界条件对重整特性的影响规律；最后通过分离与量化废气-天然气重整制氢反应机制中单个反应所做出的贡献以及对最终产物分布的影响，阐释了船用发动机估废气-天然气重整制氢的微观机理。
