Processing of lignocellulosic biomass

A plant and process for performing thermolysis of cellulose uses a thermolysis reactor which comprises a reactor duct having a longitudinal axis, and an eductor at one end of the reactor duct. The eductor has an entry chamber and a venturi-shaped exit channel, a nozzle, a sloping deflector plate abo...

Zusammenfassung:	A plant and process for performing thermolysis of cellulose uses a thermolysis reactor which comprises a reactor duct having a longitudinal axis, and an eductor at one end of the reactor duct. The eductor has an entry chamber and a venturi-shaped exit channel, a nozzle, a sloping deflector plate above the nozzle, and an inlet port through which particulate material may be fed onto the deflector plate and into the entry chamber. The nozzle and the venturi-shaped exit channel are aligned with the longitudinal axis. A superheater provides superheated steam at a temperature above 450° C. to flow through the nozzle. The particulate matter is entrained in the flowing steam, and undergoes thermolysis. This may be combined with a pre-treatment to hydrolyse hemicellulose, so that lignocellulosic biomass can be processed.
