The biomass waste orange peel was used as raw material to prepare orange peel carbon material by pyrolysis. Then, the cobalt-orange peel carbon catalyst was constructed by one-step liquid phase reduction method with orange peel carbon as the support. The catalyst was used to catalyze the conversion of ethyl levulinate (EL) to γ-valerolactone(GVL).The catalysts were characterized by SEM, XRD, FT-IR and TG. The results showed that the cobalt particles were uniformly distributed on the surface of the carbon support, with the particle size of 0.1-2 μm. The orange peel carbon support was rich in oxygen-containing structure. The Co-orange peel carbon catalyst prepared at 300℃ with the loading amount of Co 20% was used as hydrogen transfer catalyst and had good catalytic effect and stability for the conversion of EL to GVL. After 5 h reaction at 160℃ with isopropanol as liquid hydrogen source, the conversion of EL was up to 99.3%, and the yield of GVL was 85.2%. The catalytic performance decreased after reused for 4 times.

Key words: orange peel, hydrogen transfer catalyst, catalytic hydrogenation, ethyl levulinate, γ-valerolactone
