Title:
METHOD OF ENRICHMENT OF A GAS PRODUCED BY TORREFACTION AND PYROLYSIS OF BIOMASS WITH METHANE AND APPARATUS FOR IMPLEMENTING THE METHOD
Document Type and Number:
WIPO Patent Application WO/2022/253366
Kind Code:
A1
Abstract:
The object of the invention is a method of enrichment of a gas produced by torrefaction and pyrolysis of biomass with methane and an apparatus for implementing said method. According to the method, the biomass is first introduced into at least one torrefaction reactor (3), where it is subject to torrefaction at a temperature of 50 °C to 400 °C and a pressure of -50 kPa to +100 kPa, and then it is introduced into at least one pyrolysis reactor (7), where it is subject to pyrolysis at a temperature of 400 °C to 800 °C and a pressure of -50 kPa to +100 kPa to produce pyrolysis gas. During pyrolysis, a catalyst selected from the group consisting of nickel nanoparticles, copper nanoparticles, cobalt nanoparticles, platinum nanoparticles, palladium nanoparticles, ruthenium nanoparticles, rhodium nanoparticles, molybdenum nanoparticles, mercury nanoparticles and rhodamine 6G, or any combination thereof, is added to the biomass. Alternatively or in addition, before pyrolysis, preferably during torrefaction and/or after torrefaction outside the torrefaction reactor (3), a catalyst selected from the group consisting of cobalt nanoparticles, platinum nanoparticles, palladium nanoparticles, ruthenium nanoparticles, rhodium nanoparticles, molybdenum nanoparticles, mercury nanoparticles, rhodamine 6G, and a combination of nickel and cobalt nanoparticles, or any combination thereof, is added to the biomass. The addition results in a methane-enriched gas with a methane content of 10 to 60 vol. %. The present invention further relates to a use of said catalysts for enriching a gas produced by torrefaction and pyrolysis of biomass with methane, a computer program [product], a computer-readable medium and a data signal carrier.
