A process for preparing a mixture of biomass, the biomass mixture and its use

摘要

It is described a method in which in the first step are mixed at least two types of phytomass, the content of each of the components of the mixture is between 5 and 95% by weight. In the second step, the mixture is agitated, fragmented, seeded and homogenized and subsequently dried. One type of phytomass is crushed wood waste with fragmentation from 25 to 60 mm and the second type is a straw, pretreated packages, crushing and blending, with a natural moisture content. The method may further comprise admixing the other type of biomass, which is a grain, chaff sawdust or shavings with a moisture content of 25% and particle size of the range of 0.1 to 15 mm. The biomass mixture prepared in this way is homogeneous and contains from 5 to 50%, preferably from 20 to 35 wt %. cellulose, hemicellulose and lignin, and a particle size of up to 10 mm, preferably 5 to 10 mm. The biomass composition is suitable for use as raw material for pyrolysis.
