摘要：Catalysts, such as HZSM - 5 ( Si/Al = 50), HZSM - 5(25), zeolite 5A, CaHZSM - 5(50), ZnHZSM - 5(50), and Kaolin were used in upgrading of crude biomass oil from pyrolysis in a fixed bed reactor under atmospheric pressure in order to investigate effects of catalyst type on the yield of desired product. A blank run was carried out in a bed of inert packings to determine how the non-catalytically thermal cracking affected the results. The gas produced in the reaction was analyzed by chemical absorption method. Among those catalysts, HZSM - 5 (50) gave the highest yields of the desired organic distillate while Kaolin gave the slowest formation rate of coke. Regeneration of deactivated HZSM - 5(50) was studied. In terms of yield of organic distillate and formation rate of coke, results showed that catalytic activity didn't change much during the first 3 times of regeneration.
