Abstract
Official abstract text for this publication.
Provided is a process for producing biomass-based product from straw hemicellulose and utilizing the components thereof thoroughly. Steam-explosion and acid-hydrolysis are combined in the pre-treatment of straw in the process, thus a higher concentration of a sugar liquid can be obtained, and furfural and acetic acid can be recovered. The hemicellulose obtained by the pre-treatment can be used directly as ferment materials for producing butanol, succinic acid, butylene glycol, lactic acid, hydrogen and firedamp, which reduces the cost of these biomass-based products. The cellulose and lignin obtained by extracting the straw with an alkaline solution can produce products, such as sodium hydroxymethyl cellulose etc. In the process, all components in the straw can be utilized thoroughly and waste and pollutant will not be produced.
First claim
Opening claim text (preview).
The invention claimed is: 1. A process for producing a bio-based product from straw hemicellulose, comprising the steps of: 1) pretreating straw, wherein the straw is soaked in water, wherein a mass ratio of straw to water is from 1:1 to 1:3, a soaking temperature is from 15° C. to 90° C., and a soaking period is from 10 mins to 60 mins; 2) conducting steam explosion, wherein the straw soaked in step 1) is fed into a steam-explosion tank, and maintained under a steam-explosion p…
