Autohydrolyzed Low-Cost Biomass and Adsorbent Aging

Abstract

Autohydrolysis or self-hydrolysis or hydrothermal treatment of lignocellulosic materials like sawdust and straw is already used in bioethanol industry for water soluble fermentable sugars production. The main idea in this paper is the use of the autohydrolysis and other thermochemical treatments’ solid residue as an adsorbent. In this study continuous fixed-bed-column systems were investigated. Continue-flow experiments were carried out on stainless steel columns with dimensions 15 × 2.5 and 25 × 2.5 cm. In chemical processing, a packed bed is a hollow tube, pipe, or other vessel that is filled with a packing material.
