Abstract
A treatment method for biomass, which is a pretreatment method including continuously performing hydrothermal treatment using a screw extruder to produce a biomass composition for saccharification from cellulose-containing biomass and containing only a small quantity of furfural, the treatment method sequentially including: pulverizing the cellulose-containing biomass so as to have a maximum grain size of 1,000 μm or less and adjusting a water content ratio thereof to from 30% to 80%; performing hydrothermal treatment in which an element including a seal ring and at least one set of a kneading disc and/or a left-hand screw is arranged immediately upstream of the seal ring, at a temperature of (1) from 150° C. to 200° C. or (2) from 200° C. to 215° C. for 0.1 minute to 15 minutes while performing kneading pulverization having a grinding effect; and cooling a treated product to 100° C. or less to recover the treated product.
