Steam Reforming of Model Compounds from Bio-Oil for Hydrogen Production over Pd/HZSM-5 Catalyst

Abstract:

Ethanol was selected as a model compound of bio-oil. Pd/HZSM-5 catalyst with 5%wt Pd was prepared by wet impregnation method. The steam reforming experiment for hydrogen production was carried out on a fixed bed reactor. The carbon conversion, carbon selectivity of product gas and H2 yield was calculated according the experimental resultsl. It has been found that the best performance was obtained at T=700°C, S/C=9.2 and GC1HSV=346h-1. At this condition, the hydrogen yield and potential hydrogen yield can be as high as 58.1% and 84.3%. The results show that the addition of Pd to HZSM-5 can improve the reforming performance and increase the hydrogen yield.
