Abstract: To provide a hydrocarbon reforming/trapping material which is capable of adsorbing and reforming a hydrocarbon. A hydrocarbon reforming/trapping material of the present invention has an SiO2/Al2O3 ratio of from 7 to 12, and contains an Fe(II)-substituted beta zeolite which is ion-exchanged by Fe(II) ions. The amount of supported Fe(II) is preferably 0.001-0.5 mmol/g with respect to the Fe(II)-substituted beta zeolite. This Fe(II)-substituted beta zeolite is suitably produced by dispersing and mixing a beta zeolite having an SiO2/Al2O3 ratio of from 7 to 12 in an aqueous solution of a water-soluble compound of divalent iron, and mixing and stirring the solution, so that Fe(II) ions are supported on the beta zeolite.

Abstract: A self-assembling structure using non-equilibrium driving forces leading to “living crystals” and other maniputable particles with a complex dynamics. The dynamic self-assembly assembly results from a competition between self-propulsion of particles and an attractive interaction between the particles. As a result of non-equilibrium driving forces, the crystals form, grow, collide, anneal, repair themselves and spontaneously self-destruct, thereby enabling reconfiguration and assembly to achieve a desired property.

Abstract: It is disclosed a continuous process for soaking a ligno-cellulosic biomass stream in an extraction solution comprising water and dissolved water soluble species derived from a previously treated ligno-cellulosic biomass, wherein the soaked ligno-cellulosic biomass stream is optionally rinsed with a rinse solution stream to produce a soaking liquid. The electrical conductivity of the extraction solution and/or the soaking liquid are controlled to a value in a suitable target range by regulating one or more dilution streams. The disclosed process is useful to remove non-ligno-cellulosic water soluble compounds from the ligno-cellulosic biomass with a low consumption of water.

Abstract: Methods and compositions for processing biomass using [Co(CN)5]3? are disclosed. The resulting products include monomeric carbohydrate units that can also be converted to basic alcohols, including ethanol, for a variety of uses including transportation fuels and the generation of electricity.
Abstract: Provided are methods and compositions using activated carbon for optimizing purification and clarification of sugar streams produced from cellulosic or lignocellulosic biomass. Also provided are methods and compositions for decreasing one or more undesirable products during pretreatment.
Abstract: This specification describes a process of producing a monomeric sugar stream ligno-cellulosic biomass without enzymes or acid catalysts. This is accomplished by removing the water soluble C5 sugars from the ligno-cellulosic biomass feedstream, lowering the pH of the C5 solution with little or no addition of an acid, thermally treating the remaining ligno-cellulosic biomass, combining the thermally treated ligno-cellulosic biomass with the low pH C5 solution and then exposing the mixture to an elevated temperature greater than 80° C. for a time sufficient to hydrolyze at least some of the components of the ligno-cellulosic biomass. Preferably, the thermally treated ligno-cellulosic biomass is subjected to a fiber shives reduction step to reduce the amount of long fiber shives.

Abstract: The present invention is directed to a process for producing spinnable cellulose at least in part from citrus fruits, such as oranges and lemons. In a preferred embodiment, cellulose is extracted from citrus fruits, discarded by the citrus fruits plantations and/or from parts of citrus fruits, waste of the industrial processing of citrus fruits derivatives. Cellulose is extracted from the entire peel of citrus fruits, which includes both albedo and flavedo, or only from albedo. Preferably, cellulose is obtained by chemical extraction, preferably in the absence of chlorine, comprising the treatment of raw materials derived from citrus fruits with hydrogen peroxide under basic conditions. Cellulose obtained by the process of the present invention is optionally mixed with cellulose obtained by different processes, for example with cellulose extracted from wood.
