A process and system for separating bio-gasoline, bio-diesel and bio-fuel oil fractions from a bio-oil, and for producing a renewable gasoline including at least in part the bio-gasoline fraction, is provided. The process comprises separating bio-oil into a bio-gasoline fraction and a heavy fraction based on their boiling points. At least a portion of the bio-gasoline fraction is directly blended with a petroleum-derived gasoline, without any prior hydrotreatment, to thereby provide a renewable gasoline composition.

There is provided a method for blending coals for coke production, in which the strength of coke produced from a coal blend serving as a raw material is estimated using a physical property that has not been taken into consideration in the past as an index, so that the method is capable of suppressing an increase in the raw material cost of the coal blend and increasing the strength of coal. Two or more coal brands are blended together to provide a coal blend for coke production. When the two or more coal brands are blended together, the coal brands and the blending ratio of the coal brands are determined using the surface tension of each of the coal brands subjected to heat treatment, the surface tension serving as a control index.

The present disclosure generally relates to systems and methods utilizing regenerative agriculture for the procurement, production, refinement and/or transformation of low carbon intensity transportation fuels, including low carbon intensity biodiesel and/or renewable diesel, low carbon intensity biogasoline, low carbon intensity aviation, marine and kerosene fuels as well as fuel oil blends, low carbon intensity ethanol, and low carbon intensity hydrogen, that may be beneficially commercialized directly to consumers. In further aspects, the systems and methods of the present disclosure advantageously generate low carbon intensity comestibles, including sustainably-sourced meal and/or feed. The disclosed systems and methods may be utilized and optimized such that the resulting fuels and foodstuffs are characterized by a reduction in greenhouse gas production and a diminution in the fertilizer, pesticide and water required for producing the associated crop feedstocks.

The invention concerns a purification method comprising: providing a flow comprising a glycol, monovalent ions and multivalent ions; treating this flow with ion exclusion chromatography comprising: injecting the flow into a chromatographic unit comprising an ion exchange stationary phase; injecting an eluent into the chromatographic unit; collecting a fraction at the outlet of the chromatographic unit; the collected fraction being enriched with glycol and depleted of monovalent ions and multivalent ions relative to the flow.

The invention also concerns an installation adapted to implement this method, and its application to the regeneration of an anti-hydrate agent.

The present invention relates to a method and system for torrefaction of biomass and combustion of generated torrefaction gases. The torrefaction gases released from the biomass during the torrefaction reaction are withdrawn from the reactor and into a first burning zone. A secondary stream of air is introduced to the first burning zone to combust the torrefaction gases whereupon hot flue gases are obtained. Part of the hot flue gases are directed to a mixing unit. The rest of the hot flue gas is directed to a second burning zone for complete combustion of the flue gases. The fully combusted flue gases obtained in the second burning zone are directed to a heat recovery unit where the temperature of the flue gas is decreased. Part of the cold flue gases are directed to the mixing unit where it is mixed with the hot flue gases such that a stream of cooled flue gases is obtained. The stream of the cooled flue gases are diverted into the torrefaction reactor for direct heating of the biomass.

Provided is a technique by which the compatibility between coals for cokemaking can be quantitatively determined to estimate the coke strength taking into account the compatibility and to select and blend coals based on the coke strength estimated taking into account the compatibility, thereby allowing the production of a coke with the desired strength. A method for blending coals for cokemaking includes predicting the strength of a coke to be produced from a blend of a plurality of coals based on a difference between the surface tensions of the plurality of coals after heat treatment and determining the types and proportions of the coals to be blended.

The invention relates to a method for removing absorbable gases from pressurized industrial gases contaminated with absorbable gases, without supplying cooling energy. The method includes an industrial gas that is to be purified is purified by an absorbent solvent, the absorbable gases situated therein being removed by the solvent, and the loaded solvent is passed to a stripping stage in which the absorbed gas is desorbed again, and the desorbed gas is compressed, in such a manner that it is heated by the compression, whereupon it is cooled to standard temperature by means of cooling water or cooling air, then expanded, in such a manner that it cools and this cooled desorption gas is again returned to the industrial gas, in such a manner that said industrial gas is also cooled by the admixture.

A method and an industrial plant for separating a waste material comprises at least one metal and at least one organic material. A separated fraction of the waste material is provisioned which is isolated from the waste material in the course of a mechanical preparation operation. The separated fraction comprises briquettes produced from the waste material, and optionally a coarse fraction of the waste material or of another waste material. A reactor is charged with the separated fraction and gas containing oxygen is introduced into the reactor and the separated fraction is combusted in an incomplete combustion process. The separated fraction is melted into a liquid slag phase and into a liquid metal-containing phase. The slag phase and/or the metal-containing phase are poured off from the reactor.

Traditional residential and industrial furnace systems convert the chemical energy of liquid and gas fuels into thermal energy and, in some earlier applications, also into electric energy. This process is driven by a burner specifically designed and built. Often these systems operate at high temperatures, high pressures and relatively lower efficiency levels. The field of present invention generally relates to furnaces that combine the fuel production to the both thermal either electrical energy production. More particularly, the present invention produces a combustible gas that, within the internal workings of the present invention, and can efficiently be burned without the production of high levels of pollutants, at relatively lower temperatures and pressures. The foregoing characteristics, along with the limited size of the elements needed to practice the present invention, make it conducive for use as and in connection with, among other things, residential furnaces and other heating systems, including, for example, heat exchangers and residential hot water tanks. In short, the present invention involves the production of a combustible fuel gas, thermal and electric energy. This production is accomplished through the interconnected use of water electrolysis, catalysts, storage means, regulation, and mean of reusing materials to increase production efficiencies.
