The invention discloses a dual-functional catalyst composition and an integrated process for production of olefin epoxides including propylene oxide by catalytic reaction of hydrogen peroxide from hydrogen and oxygen with olefin feeds such as propylene. The epoxides and hydrogen peroxide are preferably produced simultaneously in situ. The dual-functional catalyst comprises noble metal crystallites with dimensions on the nanometer scale (on the order of <1 nm to 10 nm), specially dispersed on titanium silicalite substrate particles. The dual functional catalyst catalyzes both the direct reaction of hydrogen and oxygen to generate hydrogen peroxide intermediate on the noble metal catalyst surface and the reaction of the hydrogen peroxide intermediate with the propylene feed to generate propylene oxide product. Combining both these functions in a single catalyst provides a very efficient integrated process operable below the flammability limits of hydrogen and highly selective for the production of hydrogen peroxide to produce olefin oxides such as propylene oxide without formation of undesired co-products.

In another embodiment, the invention relates to a conical auger fractionation column. The fractionation column includes a column body having an input and an output. A conical filter is positioned inside the column body, the filter having a larger diameter end directed toward the input and a smaller diameter end directed toward the output. A conical auger is positioned inside the conical filter, the conical auger having an outer diameter which is approximately the same as an inner diameter of the conical filter. The auger and filter are adapted to cooperate to separate cellulosic solids from a liquid stream in a process of producing bio-ethanol from a lignocellulosic material.

A method in which a parent hydrocarbon-rich material is processed so as to produce both a carbon-rich solid material that has a higher carbon to hydrogen ratio than that of the parent material and a carbon-deficient combustible gas that has a lower carbon to hydrogen ratio than the parent material. In the process, the material is activated by exposing it to a hot gas stream having elevated levels of one or both of carbon dioxide and water vapor. The combustible gas is combusted to produce heat. At least about 80% of the heat is used in one or more endothermic steps that include drying coal or biomass.

An improved method for processing corn into ethanol and other valuable co-products. The invention generally involves a multi-step process which produces germ (or oil), protein, and feed yeast as its co-products while maintaining or enhancing the provision of fermentable sugar to ethanol fermentation. This is accomplished by fundamentally altering the way the corn is fractionated, disrupting the cell walls rather than the protein matrix as is done in conventional wet milling.

This invention relates a series of steps to provide an economical production of a carbon based fertilizer and soil amendment made during the capture of greenhouse gases from the combustion of fossil and non fossil fuels. The invention uses biomass and other carbonaceous sources through pyrolytic conversion to gases and charcoal, to allow for the further production of co-products, such as hydrogen and ammonia. The invention also relates to the combination of hydrated ammonia, combustion flue gas exhaust, and charcoal, provide for the conversion of the charcoal into a valued added soil amendment to return essential trace minerals and plant nutrients to the soil. The ability to produce a large volume carbon co-product while removing mandated emissions and producing renewable based hydrogen provides an economic gain to a large number small and large businesses and increase the chance of achieving significant reductions in greenhouse gas emissions.

A method for the gasification of a hydrocarbon-bearing feedstock to produce useful co-products such as high-value hydrocarbon fuels, pure H₂, electricity, and/or ammonia. The method advantageously gasifies the carbon in the feedstock to carbon monoxide (CO) without producing large quantities of carbon dioxide (CO₂). Supplemental hydrogen (H₂) is also produced by reacting steam (H₂O) with a metal. The method can advantageously produce two separate syngas streams, one that is CO-rich and one that is H₂-rich.

The invention provides a method and apparatus for reducing the energy needed to process stillage in an ethanol refining operation. The method involves adding to stillage an effective amount of at least one processing aid. The flocculant induces the separation of insoluble material that would otherwise remain suspended in water but which impose a high shear energy cost on the refining processes. This allows for the removal of insoluble material that would otherwise be overlooked but which increase energy costs. This allows for more efficient and effective separation and recovery of insoluble fractions of the concentrated thin stillage that would otherwise be overlooked and lost in the process. Loss of these valued fractions as a result of traditional processing techniques and those requiring extensive additional energy input results in the loss of high value co-products to low revenue process streams. This allows stillage to be processed more rapidly with a lower energy cost and improved co-product recovery economics.

In this joint product, the nugget area in the joint part is from 20×t₂^0.5 to 100×t₂^0.5 mm², the area of a portion where the thickness of the interface reaction layer is from 0.5 to 3 μm is 10×t₂^0.5 mm² or more, and the difference between the interface reaction layer thickness at the joint part center and the interface reaction layer thickness at a point distant from the joint part center by a distance of one-fourth of the joint diameter D_c is 5 μm or less. According to this construction, there can be provided a dissimilar material joint product with excellent bonding strength, which can be formed by an existing spot welding apparatus at a low cost without newly using other materials such as clad material or without newly adding a separate step, and a spot welding method for the dissimilar material joint product.

The disclosed integrated manufacturing process includes a combined liquid phase reaction and purification operation which directly produces trans-1-chloro-3,3,3-trifluoropropene and 3-chloro-1,1,1,3-tetrafluoropropane which is a precursor to the manufacture of trans-1,3,3,3-tetrafluoropropene. The mixture of co-products is easily separated by conventional distillation and 3-chloro-1,1,1,3-tetrafluoropropane is then dehydrochlorinated to produce trans-1,3,3,3-tetrafluoropropene by contacting in the liquid phase with a caustic solution or in the vapor phase using a dehydrochlorination catalyst.

A gasifier combines two reactors using externally generated preheated high temperature steam injection into the first reactor, where the heating demand for gasification is supplied by the sensible energy from the steam. The gasifier can produce a medium and higher LCV syngas. The first reactor is a fixed bed gasification section where the coarse feedstock is gasified, and the second reactor is an entrained-bed gasification section where the liquid and fine feedstock is gasified. Solid coarse feedstock is devolatilized in the first fixed bed reactor of the gasifier with high-temperature steam, and subsequently, in the second reactor subjected to a higher temperature sufficient to crack and destroy tars and oils. Activated carbon may be formed as co-product. The gasifier may be used with various solid and liquid feedstocks. The gasifier is capable of gasifying such different feedstocks simultaneously.
