Application number: 20120096762
Abstract: Biomass based feeds are processed under hydrothermal treatment conditions to produce a hydrocarbon liquid product and a solids portion. The solids portion can contain a portion of the phosphorus from the biomass feed. The amount of phosphorus in the solids portion can be increased for some biomass feeds by adding a multivalent metal to the feed. The phosphorus from the solids portion can be recycled for further use, such as for growth of additional biomass.

Application number: 20120090221
Abstract: Methods, process, apparatus, equipment, and systems are disclosed for converting biomass into bio-oil fractions for chemicals, materials, feedstocks and fuels using a low-cost, integrated fast pyrolysis system. The system improves upon prior art by creating stable, bio-oil fractions which have unique properties that make them individually superior to conventional bio-oil. The invention enables water and low-molecular weight compounds to be separated into a final value-added fraction suitable for upgrading or extracting into value-added chemicals, fuels and water. Initial bio-oil fractions from the process are chemically distinct, have low-water content and acidity which reduces processing costs normally associated with conventional bio-oil post-production upgrading since fewer separation steps, milder processing conditions and lower auxiliary inputs are required. Biochar is stabilized so that it can be handled safely.

Abstract: A process is disclosed for preparing fluidizable particles of a biomass/catalyst composite material. The process comprises the steps of (i) providing a particulate, solid biomass material; (ii) forming a composite of the biomass material and a catalytic material; (iii) subjecting the biomass material to a thermal treatment at a torrefaction temperature at or above 200° C., and low enough to avoid significant conversion of the biomass material to liquid conversion products; and (iv) forming fluidizable particles from the biomass material. Step (ii) may be carried out before or after step (iii).
