Synergistic co-pyrolysis of biomass and methane for hydrocarbon fuels and chemicals production

Abstract

There are provided herein novel catalytic approaches of producing deoxygenated bio-oil in fast pyrolysis reaction conditions. In one embodiment, HZSM-5 zeolite was modified by loading bimetallic catalyst compounds, resulting in new catalysts including MoAg/HZSM-5 and MoZn/HZSM-5. Both catalysts showed higher reactivity towards methane activation than molybdenum-only loaded catalysts. MoAg/HZSM-5 tended to catalyze dealkylation of alkylated benzenes thus yielded a product with high selectivity towards benzene. A dramatic increase in the yield of aromatic hydrocarbons was noticed when MoZn/HZSM-5 was used for catalysis of switchgrass under methane atmosphere. The final liquid hydrocarbons targeted according to this embodiment are benzene, toluene, ethylbenzene, xylene, naphthalene (BTEXN).
