Adsorption of lignocelluloses of model pre-hydrolysis liquor on activated carbon
Bioresource Technology, 2013The main objective of this work was to study the adsorption behavior of various components dissolved in the pre-hydrolysis of kraft process on activated carbon. In this work, model prehydrolysis liquor (PHL) solutions (MPHL)s were prepared via mixing various commercially available monosugars, xylan, lignin and furfural; and their adsorption performance

Study on Pre-Hydrolysis Technology of Reed Artificial Fiber Pulp
Advanced Materials Research, 2013The main materials of artificial fiber pulp are natural fiber from wood and linters etc. However, it will be more and more difficult to make this pulp in China because of the scarcity of forest resource and cotton field. Reed is widely distributed with high yield in china. Therefore, exploitation and utilization of reed in artificial fiber pulping have

Pre-hydrolysis with carbohydrases facilitates the release of protein from brewer’s spent grain
Bioresource Technology, 2013Brewer's spent grain (BSG) is the most abundant side-stream from brewing. It is food-grade being rich in dietary fibre and protein and thus having potential as their source for both food and non-food applications. Initial treatment of milled BSG with a carbohydrase cocktail from Humicola insolens significantly enhanced the subsequent solubilisation of ...

Gel formation in mullite precursors obtained via tetraethylorthosilicate (TEOS) pre-hydrolysis
Journal of Materials Science, 1997Tetraethylorthosilicate (TEOS) and aluminium chloride were taken as sources of SiO2 and Al2O3 to prepare precursors of mullite by pre-hydrolysis of TEOS under refluxing conditions. Gelation was carried out at different pH values and the effect of the pH of gelation on the subsequent temperature-induced phase transformations was characterized by ...

Simulation analysis of producing xylitol from hemicelluloses of pre-hydrolysis liquor
Chemical Engineering Research and Design, 2014Abstract The pre-hydrolysis liquor (PHL) of the kraft-based dissolving pulp production process is currently sent to the recovery boiler and incinerated. However, PHL contains about 5–8% lignocelluloses that can be utilized in the production of value-added chemicals.

Pre-hydrolysis liquor (PHL) from the kraft-based dissolving pulp process contains large amounts of hemicelluloses, which is usually treated as an effluent and further efforts have to be involved to eliminate the pollution disposal. However, the hemicelluloses-rich PHL is a promising candidate for the production of carbon microspheres via hydrothermal ...

In this paper, we proposed a new modification for an ethanol-based pulping process, which would consist of the pre-hydrolysis (pre-extraction) of wood chips for removing hemicelluloses; the ethanol extraction of pre-hydrolyzed wood chips for removing lignin; and the post purification of cellulose, leading to the production of pure cellulose.

Enzymatic pre-hydrolysis and anaerobic degradation of wastewaters with high fat contents
Biotechnology Letters, 2001Dairy wastewaters containing elevated fat and grease levels (868 mg l−1) were treated in an upflow anaerobic sludge blanket reactor (UASB) and resulted in effluents of high turbidity (757 nephelometric turbidity units), volatile suspended solids up to 944 mg l−1 and COD removal below 50%.

Abstract The removal of the lignin from the pre-hydrolysis liquor (PHL) of kraft-based dissolved pulp production is essential for the utilization of the saccharides in PHL. Horseradish peroxidase (HRP) was used to treat the PHL, and the treatment conditions for lignin removal were optimized, and the novel combined processes of HRP treatment and ...
