METHOD FOR SCALE REMOVAL DURING A LIGNOCELLULOSIC CONVERSION PROCESS |
摘要 |
A method for processing of a lignocellulosic feedstock is provided comprising exposing lignocellulosic feedstock to acid in a reactor to hydrolyze at least hemicellulose present in said lignocellulosic feedstock, wherein during said exposing, a scale deposit comprising lignin forms on the inner surface of said reactor; and treating the scale deposit with an alkali solution at a temperature between about 140° C. and about 250° C. so as to remove scale. Also provided is a method for reducing scale deposit that forms on process equipment during a stage of reacting a lignocellulosic feedstock with acid. |
