Title:
PROCESS FOR THE PRODUCTION OF BIO-OIL AND BIOGAS FROM BIOMASS
Document Type and Number:
WIPO Patent Application WO/2020/021127
Kind Code:
A8
Abstract:
The present invention relates to a process for the production of a liquid fuel and of a gaseous fuel from biomass. The biomass is sent to a pre-treatment section to form a homogeneous phase that can be moved and/or pumped, where inert parts are separated from the biomass, and the biomass is shredded and/or ground to reduce its size. The homogeneous phase obtained is then subjected to subcritical hydrothermal liquefaction at a temperature between 240°C and 310°C to form a liquefied phase. Said liquefied phase, the output of liquefaction, is then subjected to a separation. After separation, the process continues in two alternative and mutually exclusive modes. In the first mode,the first aqueous phase is subjected to an anaerobic reaction with multiple stages producing biogas; the oily phase coming out of the separation is then separated into a bio-oil and a solid residue. In the second mode,the separate mixed phase is then subjected to a separation by different density or dynamics forming a first aqueous phase, bio-oil and a gaseous phase.The first aqueous phase is then subjected to a multiple-stage anaerobic reaction from which biogas, a muddy current and a second aqueous phase are produced.
