Methods are disclosed for the continuous treatment of biomass comprising a pretreatment step, wherein said biomass is contacted with a first supercritical, near-critical, or sub-critical fluid to form a solid matrix and a first liquid fraction; and a hydrolysis step, wherein said solid matrix formed in said pretreatment step is contacted with a second supercritical or near-supercritical fluid to produce a second liquid fraction and an insoluble lignin-containing fraction. Also disclosed are apparatuses for the continuous conversion of biomass comprising a pretreatment reactor and a hydrolysis reactor associated with said pretreatment reactor.

Methods are disclosed for increasing the yields of fermentable Csugars from lignocellulosic biomass by using a multistage cellulose hydrolysis and quench, with or without acid.

Multistage cellulose hydrolysis and quench with or without acid

Methods of making glucose and/or furfural from biomass require one or more supercritical fluids that may be used to process biomass, cellulose from the biomass, and/or xylose from the biomass. Examples of supercritical fluids for use in processing biomass include ethanol, water, and carbon dioxide at a temperature and pressure above the critical points for ethanol and carbon dioxide but at a temperature and/or pressure below that of the critical point for water. A supercritical fluid containing carbon dioxide and water may be used to convert cellulose to glucose or convert xylose to furfural. The fluid has a temperature and pressure above the critical point of carbon dioxide, but at least one of the temperature and pressure is below the critical point for water.

Nano-catalytic-solvo-thermal technology platform bio-refineries

The invention relates to a process for hydrolyzing cellulose, comprising: (a) contacting cellulose with a fluid mixture comprising supercritical COand sub-critical or near-critical water to form a reactant mixture at a first temperature and first pressure for a first time period, wherein a reaction occurs and forms one or more hydrolysis products; (b) quenching the reaction; and (c) recovering at least one hydrolysis product.

Solvo-thermal hydrolysis of cellulose

A method of making cementitious particles using combustion synthesis is described. The method uses less energy and produces lower COemissions than conventional processes. By controlling the process conditions, the morphology and the properties of the particles can be easily tuned for a variety of applications. A batch reactor and a continuous conveyor type reactor that can be used for the combustion synthesis with high viscosity raw materials are also described.
