Abstract To make clear the feasibility and influence factors of diesel fuel autothermal reforming to hydrogen, PdCeCr- FeCu/Al2O3 catalyst was prepared by equivalent-volume impregnation method. Experimental facility based on an adiabatic tubular reactor with preheating section was designed and set up, the behaviors of diesel reforming to hydrogen with straight-run diesel as a raw material according to the analysis of the components were studied. Diesel oil reforming over a catalyst for hydrogen production was analyzed using an adiabatic tubular reactor with a preheating section that was designed and built in-house. The operating conditions were optimized. Under the suitable operating conditions, viz., catalyst bed inlet temperature of 700 °C, diesel liquid space velocity of 0.24 h−1, water-carbon ratio of 20, and oxygen-carbon ratio of 0.6, the hydrogen yield reached 28.3 (mol/mol).

PdCeCrFeCu/Al2O3催化制氢柴油自热重整

摘要 为明确柴油自热重整制氢的可行性及影响因素，采用等体积浸渍法制备了PdCeCr-FeCu/Al2O3催化剂。设计并搭建了基于带预热段的绝热管式反应器的实验装置，通过组分分析研究了以直馏柴油为原料的柴油重整制氢行为。使用内部设计和建造的带有预热段的绝热管式反应器分析了柴油在制氢催化剂上的重整。优化了操作条件。在合适的操作条件下，即催化剂床入口温度为 700 ℃，柴油液空速为 0.24 h−1，水碳比为 20，
