LOW TOTAL ACID NUMBER BIO-CRUDE

摘要

Disclosed is a pyrolysis product of a biomass material. This product, referred to as bio-crude, has a total acid number (TAN) of less than 10, and is suitable for processing in stainless steel equipment. A process for making the bio-crude comprises pyrolysis of a biomass in the presence of a particulate catalyst. The TAN of the bio-crude may be reduced further by reducing the bio-crude with coke and or CO produced in the process.
