Preparation of high-value furan platform compounds from Zizania latifolia stem
The conversion of biomass into high-value furan platform compounds is an important way of biomass re-sources utilization.In the present study,the industrial by-product metatitanic acid was used as a solid acid catalyst for the conversion of water bamboo(Zizania latifolia)stem to 5-hydroxymethylfurfural(HMF)and furfural.The effects of physical activation and solvent system on the hydrolysis performance of water bamboo stem were investigated and the reaction process conditions were optimised.The results showed that,due to the lower lignin content and the crystal structure of cellulose,water bamboo stem could be more easily physically activated than the water bamboo leaf.Under reaction conditions of 200 ℃ and 30 min,the activated water bamboo stem after ball milling obtained the highest yields of HMF and furfural,which were 11.66％and 7.30％,respectively.The reaction kinetics analysis showed that the activation energy of the water bamboo stem after ball milling catalysed by metatitanic acid was low,which exhibited advantages compared to other lignocellulosic biomass reported in literatures.
