Zeolite based catalyst has shown good performances for upgrading the quality of oil obtained from copyrolysis of coal and biomass. However, the use of zeolite resulted in severe coking formation of the surface of the zeolite. Loading some kinds of metals is able to decrease the coke formation to some extent. In the present study, post-treatment of the metal loaded zeolite was done in order to increase the coke resistance of the catalyst. Post-treatment by steaming process of the metal loaded zeolite was shown to have a good effect for coke resistance. The amount of the coke deposited on the treated metal loaded zeolite was lower than that on the untreated one. Steaming process could change the acidity of the zeolite so that the interaction of the zeolite surface with the coke precursor changed as well resulting in the lower amount of deposited coke.
