Carbohydrate Polymers, 2013
In this work, we aimed at adsorbing the oligo-sugars of prehydrolysis liquor on precipitated calcium carbonate (PCC) to produce modified PCC. The results showed that the adsorptions of oligo-sugars, lignin and furfural were greater on porous PCC (PCC2) than on nano-sized PCC (PCC1) due to the larger surface area of PCC2.

International Biodeterioration & Biodegradation, 2007
Abstract A pool of hydrolases with 21.4 U g −1 lipase activity was produced through solid-state fermentation of the fungus Penicillium restrictum in waste from the Orbignya oleifera (babassu) oil processing industry. Enzymatic hydrolysis and anaerobic biodegradability tests were conducted on poultry slaughterhouse effluents with varying oil and ...

Nordic Pulp & Paper Research Journal, 2018
Abstract Dissolving pulps could be considered as the future biorefineries, which normally generate liquor during the wood chip pre-hydrolysis (PHL). PHL has high chemical oxygen demand (COD) and biochemical oxygen demand (BOD). Mills do not have efficient means for disposal of PHL, being in general burned in the recovery boiler with a ...

Study on Technology of Pre-Hydrolysis Pretreament in Bagasse Dissolving Pulp Preparation Process
Advanced Materials Research, 2014This research used bagasse as raw material, through xylanase biological treatment process, preparative bagasse dissolving pulp. The optimum process conditions of sulfuric acid pre-hydrolysis were as below: Acid dosage 0.10%, 150°C, 90min. After pre-hydrolysis, cellulose content of the raw materials increased 18.45%, and pentosan decreased 14.49%.

ABE (acetone-butanol-ethanol) was produced through alkaline pre-hydrolysis, enzymatic saccharification, and fermentation using yellow poplar as a raw material. In alkaline pre-hydrolysis, 51.1% of the biomass remained as a residue. In the main woody components, the degrees of lignin and xylan removal were 94.3 and 62.0%, respectively.

Hemicelluloses in industrially produced pre-hydrolysis liquor (PHL) were precipitated with ethanol. These PHL-derived hemicelluloses (PHL-EH) and a commercial, pure birch wood xylan sample (powder form) (BWX) were bleached using chlorine dioxide (D(0) and D(1)) and hydrogen peroxide (Ep) in the D(0)EpD(1) sequence, and the chemical compositions ...

Abstract Development of the lignocellulosic‐biomass‐based biorefinery for making transportation fuels requires the production of valuable byproducts, minimizing the chemical consumables, and efficient water recovery and reuse. Our focus is on a liquid stream containing a variety of soluble lignin species and alkalinity that is produced by a novel ...
