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 preparing lignin from lignocellulosic biomass using rapid full or partial pressure reduction to separate and pulverize the lignin without fouling the equipment and with improved energy recovery.

Lignin production from lignocellulosic biomass

A method of extracting oil from algae by drying algae paste to a predetermined moisture content, contacting the algae paste with a polar solvent to make an algae-solvent solution and extracting oils from the algae paste into a solvent-oil solution, and separating extracted algae from the solvent-oil solution. An oil of whole and unhydrolyzed phospholipids, whole and unhydrolyzed glycolipids, lysolipids, and carotenoids extracted by the above method. An omega-3 fatty acid of docosahexanoic acids (DHAs) and eicosapentaenoic acids (EPAs) extracted from the above method. Isolated nutraceutical grade and pharmaceutical grade oil derived from algae and being free of toxins extracted by the above method. Isolated oil derived from algae including at least one omega-3 fatty acid of DHA and EPA at least partially in the form of whole and unhydrolyzed phospholipids and whole and unhydrolyzed glycolipids extracted by the above method.

Algae extraction process

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.
