摘要

The self-etherification of 5-hydroxymethylfurfural (HMF) to 5,5 '(oxy-bis(methylene))bis-2-furfural (OBMF) was investigated on ZSM-5, MCM-22, beta and hierarchical micro-mesoporous ZSM-5 (HMZ) catalysts. The hierarchically structured zeolites exhibited a superior intrinsic activity and good resistance to carbonaceous deposit; the latter could be ascribed to the lower mass transfer barrier in the mesopores of the HMZ catalysts. The structure-activity correlation showed that the catalytic activity mainly originated from one or several specific Bronsted acid sites, providing key clues to design efficient zeolite catalysts for producing OBMF.
