Process for producing biogas from beet slices, especially from beet sugar production

摘要

Method for producing a biogas from sugar beet cuts, especially as the remains from beet sugar production, is based in that the sugar beet remains are mixed with water forming a substrate with true dry matter 1 to 10 % by volume with postponing period from 1 to 6 days, which is hydrolyzed at the temperature 15 to 50 °C with simultaneous acidification at pH 4.0 to 6.0 with subsequent effect of methanizing bacteria releasing biogas in continuous or discontinuous multistage process.
