摘要： A process and/or system for processing a pressurized gas mixture comprising methane and at least one non-methane component by selective membrane separation. Portions of the pressurized gas mixture are withdrawn and provided as a plurality of pressurized gas streams at successively lower pressures. Each portion, provided as a respective pressurized gas stream, is provided for processing in a respective membrane system, each of which is at a different pressure level. Partially purified streams produced by one or more membrane systems are provided for processing at lower pressure levels (e.g., where they are combined with one of the pressurized gas streams). Accordingly, costs associated with recycle compression are reduced and/or eliminated.

摘要： A process for converting lignocellulosic biomass to fuel, wherein lignocellulosic feedstock is soaked in a sulfuric acid solution to demineralize the feedstock, the demineralized feedstock is pretreated at a temperature between 150ºC and 230ºC and a pH between 1 and 2.5, at least part of the pretreated material is converted to a fermentation production such as ethanol, and at least a portion of a secondary stream, such as still bottoms from the distillation of ethanol, is converted to biogas by anaerobic digestion. Soaking the lignocellulosic feedstock in sulfuric acid solution reduces the amount of sulfuric acid required for the pretreatment, and thus the amount of sulfate carried downstream to the anaerobic digestion. This increases the biogas yield and/or xylose yield. A recycling process, wherein mineralized soaking liquid produced in the soaking process is fed to cation exchange to remove minerals, reduces excess waste of the sulfuric acid and water usage.

摘要： Provided herein is a process for producing one or more products from a lignocellulosic feedstock. The process comprises treating the lignocellulosic feedstock by contacting the feedstock at least sulfur dioxide, sulfurous acid, or a combination thereof to produce a pretreated feedstock comprising one or more sulfonic acids. A process stream comprising one or more sulfonic acids is subsequently treated in a wet oxidation step to produce a stream comprising at least soluble oxidized phenolic compounds. The soluble oxidized phenolic compounds are then fed to an anaerobic digestion to produce methane. Optionally, hydrogen sulfide is produced during the anaerobic digestion. The hydrogen sulfide may then be converted to an acid selected from sulfur dioxide, sulfurous acid or a combination thereof in one or more steps. The acid may then be re-used in treatment as desired.

摘要： The present invention provides a process for producing a fermentation product from a lignocellulosic feedstock. The process comprises soaking a lignocellulosic feedstock in an aqueous solution to produce a soaked feedstock. The soaked feedstock is at least partially dewatered and the at least partially dewatered feedstock is subjected to pretreating in the presence of sulfur dioxide, sulfurous acid or a combination thereof to produce a pretreated feedstock composition. The pretreated feedstock composition is fed to an enzymatic hydrolysis in which the concentration of dissolved solids fed to the enzymatic hydrolysis is at least 50% (w/w) of the concentration of dissolved solids in the pretreated feedstock composition. The cellulose in the pretreated feedstock composition is hydrolyzed with cellulase enzymes in the presence of the dissolved solids to produce glucose. The glucose is fermented to produce the fermentation product.

The process comprises hydrolyzing the pretreated lignocellulosic feedstock with an enzyme mixture comprising at least cellulase enzymes to produce a hydrolyzed slurry comprising glucose and lignin solids. The hydrolyzing is conducted in the presence of a polymer, such as for example an aliphatic polyether. A solids-liquid separation is conducted to recover lignin solids from a process stream comprising the lignin solids and the polymer. A process stream is then obtained comprising recovered lignin solids resulting from the solids-liquid separation. Also provided are processes for recovering the polymer from the lignin solids and/or from solution.
