Abstract

Difurfurylidene acetone(F2A) was catalytic converted to long-chain hydrocarbons by a two-step hydrogenation process, low-T emperature hydrogenation over Raney Ni catalyst in a batch reactor, followed by hydrodeoxygenation (HDO) over 1wt.%Pt/SiO₂-ZrO₂ in a fixed-bed reactor. The results indicated that using methanol as solvent promoted hydrogenation of double bonds of F2A over Raney Ni due to its protonation effect. Selectivity of 1,5-di(tetrahydro-2- furanyl)-3-pentanol (II-c), the saturated alcohol form of the hydrogenated dimer, was 72.1% in the hydrogenated intermediate liquid(H-F2A). High carbon alkane yield of liquid alkanes(C8-C14) was 82.9%(mol) after the second-step HDO reaction over 1wt.%Pt/SiO₂-ZrO₂. Long operation showed the stability of 1wt.%Pt/SiO₂-ZrO₂ as HDO catalyst-deduced from the steady phase structures of the SiO₂-ZrO₂ support and Pt active centers during HDO reaction.
