| 20100281759 | MODULAR BIOMASS TREATMENT UNIT - A modular biomass treatment unit includes a first module having a pretreater and a first frame for transportation to and operation at a site adjacent to a solid biomass growth source. The pretreater is operable to process solid biomass to produce a plurality of solid biomass particles for conversion into a fuel or specialty chemical. The first frame supports the pretreater during transportation to and operation at the site adjacent to the solid biomass growth source. The modular biomass treatment unit can also include additional modules each comprising a reactor, a separator, and a frame for transportation to and operation at a site such as the site adjacent to the solid biomass growth source. | 11-11-2010 |
| 20110094147 | Process for the Conversion of Solid Particulated Biomass Materials - A process for producing bio-fuel from biomass is disclosed herein. The process includes processing the mean particle diameter of the biomass by mechanical processing to a size ranging from 1 μm to 1000 μm to form particulated biomass. The particulated biomass is mixed with a liquid hydrocarbon to form a suspension, wherein the suspension includes between 1 weight percent to 40 weight percent particulated biomass. The suspension is heated to a temperature between 50° C. and 550° C. The heated suspension is fed into a unit selected from the group consisting of a pyrolysis reactor, a fluid catalytic cracking unit, a delayed coker, a fluid coker, a hydroprocessing unit, and a hydrocracking unit; and then at least a portion of the particulated biomass of the heated suspension is converted into fuel. | 04-28-2011 |
| 20110099888 | Catalytic Hydropyrolysis of Organophillic Biomass - A process for producing fuel from biomass is disclosed herein. The process includes torrefying biomass material at a temperature between 80° C. and 300° C. to form particulated biomass having a mean average particle size from about 1 μm to about 1000 μm. The particulated biomass is mixed with a liquid to form a suspension, wherein the liquid comprises bio-oil, wherein the suspension includes between 1 weight percent to 40 weight percent particulated biomass. The suspension is fed into a hydropyrolysis reactor; and at least a portion of the particulated biomass of the suspension is converted into fuel. | 05-05-2011 |
| 20110114765 | COMMINUTION AND DENSIFICATION OF BIOMASS PARTICLES - A method is disclosed for reducing the mechanical strength of solid biomass material, in particular ligno-cellulosic biomass. The method comprises heating the solid biomass material to a temperature in the range of 105° C. to 200° C. The heat treatment, which is referred to as “toasting”, significantly reduces the mechanical energy required for reducing the particle size of the solid biomass material. | 05-19-2011 |
| 20110139596 | METHOD AND APPARATUS FOR PYROLYSIS OF A BIOMASS - A method and apparatus for effective pyrolysis of a biomass utilizing rapid heat transfer from a solid heat carrier or catalyst. Particularly, various embodiments of the present invention provide methods and apparatuses which incorporate progressive temperature quenching and rapid disengagement of the heat carrier material and reaction product. | 06-16-2011 |
| 20110139602 | REMOVAL OF BOUND WATER FROM BIO-OIL - A process and system for removing bound water from bio-oil by azeotropic distillation. The process comprises combining a bound-water-containing bio-oil with an azeotrope agent and subjecting the resulting treated bio-oil to azeotropic distillation under reduced pressure. The azeotropic distillation removes a substantial portion of the bound water from the bio-oil, thus producing a water-depleted bio-oil that is less corrosive, more stable, and more readily miscible with hydrocarbons. | 06-16-2011 |
| 20110154720 | Methods for Co-Processing of Biomass and Petroleum Feed - A process for producing fuel from biomass is disclosed herein. The process includes torrefying biomass material at a temperature between 80° C. to 400° C. to form particulated biomass having a mean average particle size between 1 μm and 1000 μm. The particulated biomass is mixed with a liquid hydrocarbon to form a suspension, wherein the suspension includes from 1 weight percent to 40 weight percent particulated biomass. The suspension is fed into a unit selected from the group consisting of a pyrolysis reactor, a fluid catalytic cracking unit, a delayed coker, a fluid coker, a hydroprocessing unit, and a hydrocracking unit, and then at least a portion of the particulated biomass of the suspension is converted into fuel. | 06-30-2011 |
