  • Cellulosic Ethanol VS Corn Ethanol How Each Works and

    Jan 26 2018  When refineries start with cellulosic biomass the production of ethanol can be slower and even more complicated After grinding the plants refineries add acid which helps unweave lignin hemicellulose and cellulose Then the acid breaks down hemicellulose into 4 component sugars Hence this process frees cellulose.
