<p>Pretreating lignocellulosic biomass material in platelet forms with a maximum size of 0.5-5 cm, to feed a gasification unit, comprises mixing the biomass with a heavy hydrocarbon cut (8) at an initial boiling point of above 350[deg] C to obtain biomass particles (2) with a moisture content of less than 10 (preferably less than 5) wt.%, where the mixture temperature is 200-300[deg] C, grinding the obtained mixture to reduce the particle size to less than 500 microns, where the formed suspension has a biomass content of less than 30 wt.%; and feeding the gasification unit with the suspension at 200-300[deg] C. An independent claim is included for entrained bed gasification using the suspension of biomass particles as charge in a heavy hydrocarbon cut, where the biomass particles are obtained from the pretreatment procedure.</p> |
