Method of producing Hodge' carbonyls and oligomeric lignin

摘要

The present invention relates to a method of converting biomass by fast pyrolyzing biomass feed in the presence of superheated steam (hydrous thermolysis) to produce a stream of water-soluble Hodge' carbonyls, a stream of water insoluble- oligomeric lignin and a stream of charcoal particulates. A soil enhancer comprising oligomeric lignin and oligomeric lignin in combination with biochar. A slow or controllable release type of fertilizer comprising oligomeric lignin melt coating N, P, K, fertilizers, optionally including bio-carbon and described by the 4-letters N,P,K,C.
