| 发明名称 | 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. | ||

| 主权项 | 1. A method for processing of a lignocellulosic feedstock comprising the steps of: a. pretreating said lignocellulosic feedstock with acid in a pretreatment reactor to make said feedstock more amenable to hydrolysis with cellulase enzymes, wherein during said pretreating, a lignin scale deposit forms on the inner surface of said pretreatment reactor; and b. treating said lignin scale deposit with an alkali solution at a temperature between about 140° C. and about 250° C. | ||
