NOVELTY - A method (M1) for syngas-production from polysaccharide containing biomass involves subjecting the biomass to enzymatic liquefaction and hydrolysis at a dry matter content above 20% into oligomers or polymers yielding a biomass slurry having a dry matter content of 20-50% and transferring the biomass slurry by pumping into a pressurized gasifier for subsequent syngas-production.    USE - For syngas production from biomass (claimed) useful for production of power, fuels, chemicals and heat; as feedstock for industrial processes producing oil-based products such as petrol, diesel, chemicals and plastics.    ADVANTAGE - The enzymatic treatment of this method enables the conversion of cellulose into polymers and oligomers resulting in a liquefaction of the biomass. The method includes steps for the removal of alkali salts such as chloride, sodium and potassium from the biomass that subsequently can be sold as feed nutrient for use in agriculture. The biomass slurry resulting from pre-treatment and enzymatic treatment of this method consists of particles less than 1 mm making them suitable for optimal utilization in a gasifier with a short residence time of only a few seconds without producing unwanted tars. The homogenized liquid can economically be pressurized using commercial pumps, and as a consequence it is possible to feed a pressurized entrained flow gasifier with biomass as bagasse, straw etc. The process results in a gas having a low alkali content that can be cooled with only minor corrosion problems and then cleaned from sulfur and other particles. The cleaned gas may be used as syngas for diesel, methanol, petrol or other chemicals or burned in a gas turbine for production of electricity. The method is economically favorable and is suitable for the handling of very diverse biomasses, which makes an efficient production of syngas possible. The liquified biomasses have a suitable particle size and dry-matter content for optimal feeding and gasification in a gasifier. The combination of thermal pre-treatment, enzymatic hydrolysis and gasification develop bio-fuel with a more efficient carbon utilization. Also, it is possible to re-deliver alkali compounds to the environment in the form of feed stuff additives.
