An advantageous process for pre-treating lignocellulosic biomass to hydrolysable polysaccharide enriched biomass with reduced amount of inhibitors of catalysis comprising steps of: providing a feedstock comprising cellulosic biomass; chopping of cellulosic biomass to have a cellulosic biomass feed material of uniform size; feeding of uniform sized feed material to a horizontal counter current extraction unit; removing excess of water from the feed material obtained from the extraction unit; soaking the extruded feed material obtained from the extraction unit; optionally removing excess of water from the feed material obtained after acid soaking; steam pre-treating the feed material obtained after removing excess of water from the acid soaked feed material; neutralizing the slurry obtained from the steam pre-treating; and optionally saccharifying the neutralized slurry.

Process for recovering higher sugar from biomass

The invention describes process for demetallation of vegetable oils and animal fats to reduce metal content below 1 ppm to make them suitable for hydroprocessing feedstocks. The process comprises acid treatment with very low concentration of acids, utilizing synergistic effect of phosphoric acid and citric acid, followed by counter-current treatment with clay without intermediate step of water washing and treatment with ion exchange resin.
