A Preliminary Study of Biorefinery Concept to Obtain Furfural and Binder-Less Panels from Hemp (Cannabis Sativa L.) Shives

Abstract

The study is related to the development of a biorefinery concept to obtain furfural from hemp shives with Al2(SO4)3 as catalyst in the pretreatment process and binder-less panels from leftover without additional adhesives. Pretreatment temperatures were 160-180°C and time 90 min. The results show that it is possible obtain furfural 64.8-67.2%, calculated from the theoretically possible, and to obtain binder-less panels from pretreated hemp shives, but it is necessary to diminish the moisture content and severity factor of lignocellulose before the pressing stage
