摘要:
Convert a methylamine (e.g. monomethylamine, dimethylamine and trimethylamine) to a mixture of olefins (e.g. ethylene, propylene and butylene) by placing the methylamine, optionally in a mixture with at least one of ammonia and an inert diluent, in contact with a microporous acidic silicoaluminophosphate catalyst or a microporous aluminosilicate catalyst.

A method is used to separate fractions from a seed. This can be done by: a) Physically breaking down the Chia seed into smaller particles; b) Adding a liquid carrier to the broken Chia seed to form a Chia liquid carrier blend; c) Optionally providing further processing of the Chia liquid carrier blend to further reduce the particle size of the Chia particles d) Optionally centrifuging the Chia liquid carrier blend; e) Optionally forming at least three discernible layers of materials within the centrifuged Chia liquid carrier blend; f) Optionally separating the composition of at least one layer from remaining layers; and g) Optionally combining the separated layers together into a desired combination/ratios h) Drying the separated layers or combined layers into a flowable powder.
摘要:
A process and catalyst for the hydro-oxidation of an olefin having three or more carbon atoms, such as propylene, to form an olefin oxide, such as propylene oxide. The process involves contacting the olefin with oxygen in the presence of hydrogen and a hydro-oxidation catalyst under reaction conditions; the catalyst comprising gold nanoparticles deposited on a nanoporous titanium-containing support, prepared by depositing a gold-ligand cluster complex onto the support to form a catalyst precursor, and then heating and/or chemically treating the catalyst precursor to form the hydro-oxidation catalyst composition. The hydro-oxidation catalyst exhibits stabilized catalyst activity, enhanced lifetime, and improved hydrogen efficiency.

Oxidatively halogenate methane by placing a feedstream that comprises methane, a source of halogen, a source of oxygen and, optionally, a source of diluent gas in contact with a first catalyst (e.g. a solid super acid or a solid super base) that has greater selectivity to methyl halide and carbon monoxide than to methylene halide, trihalomethane or carbon tetrahalide. Improve overall selectivity to methyl halide by using a second catalyst that converts at least part of the feedstream to a mixture of methyl halide, methylene halide, trihalomethane, carbon tetrahalide and unreacted oxygen, and placing that mixture in contact with the first catalyst which converts at least a portion of the methylene halide, trihalomethane and carbon tetrahalide to carbon monoxide, hydrogen halide and water.
摘要:
An encapsulated material containing an oxidation-sensitive core is covered by at least a dried synthetic organelle layer and optional additional ingredients in the organelle layer or additional layers. By using microencapsulation to mimic or otherwise adapt the storage concepts used by seeds to protect triacylglycerol cores, oxidatively unstable materials may be provided with a synthetic, seed-like oxygen-resistant protective barrier and rendered less susceptible to oxidative degradation.

摘要:
A method provides a milled whole seed product from a whole seed having at least 0.01% by total weight of oil therein. The whole seed is added to an aqueous carrier which is physically milled at a shear rate of at least 3,000 r.p.m. The shearing is continued until at least 50% by weight of seed solids will pass through a square mesh screen having 1.2 mm screen hole dimensions. The solids in aqueous carrier is collected as a suspension or dispersion in the aqueous carrier. The collected seed solids in aqueous carrier are dried to form a free-flowing powder. The free-flowing powder is rehydrated with a second aqueous medium to form a non-mucilaginous suspension or dispersion.
摘要:
A process of oxidizing an olefin having at least three carbon atoms directly to the corresponding epoxide comprising contacting the olefin with oxygen in the presence of a catalyst comprising a mixed silver-promoter metal (+2 or +3) silicate. In the direct oxidation of propylene the process yields a high selectivity to propylene oxide.
摘要:
A semi-transparent, tray-like container having a flat bottom and substantially vertical side and end walls defining a storage space has flange-like projections on each side wall inner surface in proximity to but spaced from the bottom to define, with the bottom, a retaining channel which slidably receives a removable panel assembly containing a plurality of hinged overlapping transparent envelopes which can be flipped like pages to display flat objects such as photography, stamps, recipes and the like contained therein. The retaining channel holds the panel assembly securely in place with little or no movement even when the envelope pages are turned with the result that the flat objects remain organized and in place in the container for safe storage and convenient display. The container bottom is constructed with supporting legs which may project into the opening of a like container for stacked alignment therewith to provide a system of a plurality of stacked tray-like containers. Downwardly projecting bosses on the container bottom contact the top edge of the walls of an adjacent container of the stack to provide spacing between containers. A semi-transparent lid having edges which overhang the sides of the container and a depending lip which fits inside the container opening may be placed on the container.
