Heterogeneous solid acid catalyst using biochar derived biomass and preparing method thereof

摘要

As an example of the present invention, there is provided a process for producing a solid acid catalyst, comprising the steps of: a) pyrolyzing biomass to produce a biomass, and b) heat treating the mixture containing bio-ze, sulfate and sulfate to produce a catalyst The solid acid catalyst thus prepared has excellent ester conversion and excellent physical / chemical stability, so that the catalytic activity can be stably maintained even though it is reused in the ester reaction.;
