Abstract
The present disclosure provides methods to produce substituted furans (e.g., halomethylfurfural, hydroxymethylfurfural, and furfural), by acid-catalyzed conversion of biomass using a gaseous acid in a multiphase reactor, such as a fluidized bed reactor.
Claims23
A system for producing halomethylfurfural, comprising:
- a. a solid feedstock, wherein the solid feedstock comprises biomass, sugar, or a combination thereof;
- b. a gaseous acid that has less than about 10% water by weight;
- c. a multiphase reactor configured to receive the solid feedstock and the gaseous acid and provide a reaction mixture comprising halomethylfurfural;
- and
- d. a solid-gas separator selected from the group consisting of a cyclone, a filter, and a gravimetric system, wherein the solid-gas separator is configured to receive the reaction mixture of the multiphase reactor and to provide a solid mixture and a separated gaseous acid, and wherein the solid mixture comprises halomethylfurfural.
