Title:
PRODUCTION OF HIGHER QUALITY BIO-OILS BY IN-LINE ESTERIFICATION OF PYROLYSIS VAPOR
Document Type and Number:
WIPO Patent Application WO/2010/099058
Kind Code:
A3
Abstract:
The disclosure encompasses in-line reactive condensation processes via vapor phase esterification of bio-oil to decease reactive species concentration and water content in the oily phase of a two-phase oil, thereby increasing storage stability and heating value. Esterification of the bio-oil vapor occurs via the vapor phase contact and subsequent reaction of organic acids with ethanol during condensation results in the production of water and esters. The pyrolysis oil product can have an increased ester content and an increased stability when compared to a condensed pyrolysis oil product not treated with an atomized alcohol.
