A process for producing ethanol from lignocellulosic biomass includes adding at least one of sulfur dioxide and sulfurous acid to the lignocellulosic biomass to provide an equivalent sulfur dioxide loading of at least 10 wt % sulfur dioxide to dry lignocellulosic biomass. The acidified lignocellulosic biomass is pretreated at a temperature above about 185&#xb0; C. and for a pretreatment time less than about 10 minutes, to provide a pretreated biomass composition wherein the biomass is readily hydrolyzed by enzymes. Advantageously, sulfur dioxide from at least one of the flash stream and a stream derived from the flash is recovered and recycled back into the process.

Sulfur dioxide and/or sulfurous acid pretreatment with sulfur dioxide recovery

A lateral marine thruster is disclosed for mounting to an outboard motor. The lateral marine thruster has a bi-directional thruster with a central body portion and at least one propeller, the central body portion housing at least one high torque electric motor, which is rotatably coupled to at least one propeller, the rotational axis of the high torque electric motor and the propeller being oriented perpendicular to the centerline of the outboard motor. The bi-directional thruster is secured to the anti-cavitation plate or a similar mounting location of the outboard motor to provide lateral thrust for ease of docking or mooring a vessel.

Provided herein is a process for producing an alcohol from a sugar cane derived cellulosic feedstock comprising: subjecting the sugar cane derived cellulosic feedstock comprising bagasse, leaves, tops, or any combination thereof, to silica removal selected from processes comprising sieving, screening, washing, cyclone separation or any combination thereof. The bagasse, leaves or tops, or any combination thereof, from which at least a portion of the silica has been removed is treated in one or more processing stages to produce sugar, wherein the undissolved solids content of a slurry during said processing stages reaches a weight percent of at least 15%. Thereafter the sugar is fermented with yeast or bacteria to produce the alcohol and the alcohol is concentrated and recovered.

The present invention relates to a process for generating steam and recovering salts during a lignocellulosic conversion process. The process comprises de-salting a still bottoms stream; incinerating a stream comprising lignin and the de-salted still bottoms stream in an incinerator; and utilizing the heat generated from said incinerating to produce steam. Further provided is a process that comprises feeding a concentrated still bottoms stream to a crystallizer and forming insoluble solids therein comprising salts. Furthermore, the invention relates to a process for recovering salts from a lignocellulosic conversion process, which process comprises the addition of solvent to a still bottoms stream to precipitate salts therefrom. Also provided is a still bottoms composition, a fertilizer product and a composition for incineration.

A method for processing of a lignocellulosic feedstock is provided comprising exposing lignocellulosic feedstock to acid in a reactor to hydrolyze at least hemicellulose present in said lignocellulosic feedstock, wherein during said exposing, a scale deposit comprising lignin forms on the inner surface of said reactor; and treating the scale deposit with an alkali solution at a temperature between about 140&#xb0; C. and about 250&#xb0; C. so as to remove scale. Also provided is a method for reducing scale deposit that forms on process equipment during a stage of reacting a lignocellulosic feedstock with acid.

The present invention provides a method of producing xylose from lignocellulosic feedstock. The method comprises disrupting lignocellulosic feedstock; leaching the lignocellulosic feedstock by contacting the feedstock with at least one aqueous solution for a period greater than about 2 minutes to produce a leached feedstock and a leachate; removing the leachate from the leached feedstock; acidifying the leached feedstock to a pH between about 0.5 and about 3 to produce an acidified feedstock, and; reacting the acidified feedstock under conditions which disrupt fiber structure and hydrolyze a portion of hemicellulose and cellulose of the acidified feedstock, to produce a composition comprising xylose and a pretreated feedstock. The xylose may be purified from the pretreated feedstock or it may be converted to ethanol with the pretreated feedstock.
