Outline of Final Research Achievements

Biomass pyrolysis has great potential replacing petroleum products, but the pyrolysis oil product has low heating value and stability, and improvements are needed. This project involves the development of advanced hydrodeoxygenation catalysts to reduce the oxygen content of the oil.
The catalytic hydrodeoxygenation of gammma-valetolactone (GVL) on a series of supported metal phosphide catalysts were carried out at 0.5 MPa. It was found that catalytic activity followed the order, Ni2P/MCM-41 > CoP/MCM-41 > MoP/MCM-41 > WP/MCM-41. On all catalysts, ring opening of GVL toward pentanoic acid was the main initial step with successive hydrogenation to form pentanal. Afterwards, saturated C4 hydrocarbons and CO were produced via decarbonylation over Ni2P/MCM-41 and CoP/MCM-41.
