This disclosure describes processes for using a single cellulosic feedstock or a combination of two or more different cellulosic feedstocks with a starch component to produce a fermented product. The process includes separating the components of the cellulosic feedstocks with fractionation, pretreating a component with wet fractionation with chemicals, hydrolysis and fermentation of the pretreated feedstock(s) to produce cellulosic biofuel. The process may include combining the cellulosic feedstock(s) with other components to a cook and/or a fermentation process, distilling and dehydrating the combined components to produce the bio fuel. The process may also include producing a whole stillage stream from the feedstock(s) and mechanically processing the whole stillage stream to produce a high-value protein animal feed.

A process for catalytic cracking of waste originating from pine processing industry for producing a mixture of chemical compounds, e.g., components for formulation of adhesives, foams, antioxidants, sugars, among others. Optionally, additional steps can be added to the process for processing the obtained mixtures in order to obtain purer fractions with greater commercial interest and value.

Disclosed herein are processes for ethanol production from a lignocellulosic feedstock. These processes provide DMR of lignocellulosic biomass comprising two-stage deacetylation followed by mechanical refining so as to increase fermentable sugar yield while reducing hydrolytic enzyme loading requirements.

It is an object of the present invention to provide a thickener capable of exhibiting excellent light resistance. The present invention relates to a thickener comprising cellulose fibers having a fiber width of 8 nm or less and water, wherein the thickener is a slurry or a gel, and when the thickener is filled in a colorless and transparent glass cell having an inside dimension of 1 cm in depth×4 cm in width×4.5 cm in height and the thickener is then irradiated with ultraviolet rays with a wavelength of 300 nm or more and 400 nm or less, using a xenon lamp, from the side of the maximum area surface of the glass cell, so as to be an irradiance of 180 W/m.sup.2 and an integrated light amount of 500 mJ/m.sup.2, the amount of a change in the yellowness before and after ultraviolet irradiation measured in accordance with JIS K 7373 is 10 or less.

A modified lignin reinforced rubber is obtained by subjecting a lignin to composite modification by a compound containing a carbon-carbon double bond, a compound containing a sulfur element and a compound capable of blocking a hydroxyl; the lignin is modified with the compound containing the carbon-carbon double bond, and the contained double bond and an olefin in the rubber generate a bonding effect, which improves a binding force between the lignin and the rubber; furthermore, by modifying the lignin with the compound containing the sulfur element, the lignin contains a certain amount of the element sulfur, which improves an interaction between the lignin and the rubber, improves properties of the rubber, and reduces the use of a vulcanizing agent, and further increases a replacement amount of the lignin to carbon black.

A method of manufacturing a mineral fibre thermal insulation product comprises the sequential steps of: Forming mineral fibres from a molten mineral mixture; Spraying a substantially formaldehyde free binder solution on to the mineral fibres, the binder solution comprising: a reducing sugar, an acid precursor derivable from an inorganic salt and a source of nitrogen; Collecting the mineral fibres to which the binder solution has been applied to form a batt of mineral fibres; and Curing the batt comprising the mineral fibres and the binder which is in contact with the mineral fibres by passing the batt through a curing oven so as to provide a batt of mineral fibres held together by a substantially water insoluble cured binder.
