Title: PROCESS FOR THE CONVERSION OF BIOMASS-DERIVED VAPOURS AND PROCESS FOR THE CONVERSION OF A SOLID BIOMASS MATERIAL
Abstract:
This invention relates to a process for the conversion of biomass-derived vapours, comprising: - a catalytic step, wherein at least part of the biomass-derived vapours are contacted with a catalyst at a temperature in the range from equal to or more than 350°C to equal to or less than 550°C, thereby producing a product mixture; and - a condensing step, wherein part of the product mixture is condensed in one or more condensers, thereby forming a condensed product fraction and a gaseous product fraction; wherein at least part of the gaseous product fraction is recycled to the catalytic step and combined with the biomass-derived vapours. The present invention also relates a process for the conversion of a solid biomass material, comprising: - a pyrolysis step, wherein at least part of the solid biomass material is pyrolysed, thereby producing biomass-derived vapours; - a catalytic step, wherein at least part of the biomass-derived vapours are contacted with a catalyst at a temperature in the range from equal to or more than 350°C to equal to or less than 550°C, thereby producing a product mixture; and - a condensing step, wherein part of the product mixture is condensed in one or more condensers, thereby forming a condensed product fraction and a gaseous product fraction; wherein at least part of the gaseous product fraction is recycled to the catalytic step and combined with the biomass-derived vapours.
