摘要： A method and apparatus for producing a solid biofuel from hydrocarbonaceous feedstock is described. The process includes loading a hydrocarbonaceous feedstock into a reactor vessel, adding an aqueous catalyst solution into the reactor vessel, wherein the catalyst solution resides at the bottom of the reactor vessel under the hydrocarbonaceous feedstock position, heating the reactor vessel at or above 170° C. to catalyze a reaction of hydrocarbonaceous feedstock under saturated steam conditions for a time sufficient to yield a polymeric biofuel, and isolating the polymeric biofuel from the reactor vessel.

摘要： The present invention relates to a method for the production of 5-hydroxymethylfurfural (HMF), which converts a fructose-containing component using a catalyst system comprising a solution of a salt and acid mixture at a temperature of 90 to 200° C. and leads to obtaining an HMF-containing product mixture, wherein advantageously a high HMF selectivity with significantly lower by-product formation is achieved at the same time.

摘要： The present invention relates to a new protocol for “Process development for 5-hydroxymethylfurfural (5-HMF) synthesis from carbohydrates”. A convenient, atom-economic, highly selective and cost-effective process has been developed for the preparation of 5-HMF from cellulose, hemicellulose, starch, different sources of carbohydrates and further extended to glucose and fructose.
