摘要

To improve the quality of oil derived from the fast co-pyrolysis of low-rank coal with biomass, various metal-modified ultra-stable Y type (USY) zeolites are mixed with the samples for the co-pyrolysis process. It is found that Mg-modified USY zeolite shows high catalytic activity with high coking resistance ability in this study. A further treatment of Mg-modified USY zeolite by steaming process further improves the coke resistance and the catalytic activity toward production of more hydrocarbons in the pyrolytic oil. It is indicated that Al atoms in the original zeolite framework could be dislocated by the steam treatment and a new framework consisting of Al-Mg-Si could be formed on the outside of the zeolite framework, which is beneficial to change the physical and chemical properties of the zeolite and increase the catalytic activity and coke resistance ability in the process of rapid catalytic co-pyrolysis of low rank coal with biomass.
