The ligno-cellulose that is present in numerous forms of biomass (straw, wood, branches etc.) constitutes an attractive alternative to sugars and renewable lipids and fats for the production of biofuels as it is not directly used for human consumption. Moreover, the quantity of ligno-cellulose that is available gives the potential to foresee the production of larger volumes of biofuels.
To this end, Axens provides it GaselTM Technology Suite to enable the production of ultra-clean bio-liquid fuels (BTL), notably biojet fuel and biodiesel, through the Fischer-Trospch conversion of synthesis gas (H2+CO) produced by the gasification of ligno-cellulosic biomass.
In order to improve the profitability of the process and make benefits of scale, refining petroleum residues can be co-processed in the gasification unit. Whatever feedstock used for the production, the syngas must be purified before introduction to the Fischer-Tropsch reactor in order to guarantee the performance
Axens provides the Axsorb range of products that are specially optimized for the desulfurization, drying and elimination of trace contaminants such as halogens or alkalines present in the feedstock.
