Abstract

See full text

A system for producing biocoal and biochar includes at least one rotary compression unit (RCU) having a barrel, a compression screw housed within the barrel, a feed for receiving biomass and at least one exit for releasing biochar and gasses formed in the RCU. A first exit stream is produced that includes biochar and a portion of the remaining gasses, and a second exit stream is produced that includes biocoal. A gas crossover is provided that connects the first and second exit stream having a mechanism for transporting gasses from the first exit stream to the second exit stream thereby condensing a portion of the remaining gasses into the biocoal. In one form two RCUs are included connected to two condensers.
