The image forming apparatus comprises: an ejection head which ejects droplets of a radiation curing liquid; an intermediate transfer medium on which an image is formed by the droplets ejected from the ejection head; an evaporation device which evaporates the droplets deposited on the intermediate transfer medium; a preliminary curing device which emits radiation onto the droplets deposited on the intermediate transfer medium in order to semi-cure the droplets so that the droplets do not blend with each other; and a transfer device which presses a recording medium against the intermediate transfer medium so that the image formed on the intermediate transfer medium is transferred onto the recording medium, wherein: the droplets deposited on the intermediate transfer medium are evaporated by the evaporation device; and the evaporated droplets are semi-cured by the radiation emitted from the preliminary curing device, and then the image formed on the intermediate transfer medium is transferred onto the recording medium by the transfer device.

A process and method for producing liquid fuel product from hydrogen and carbon monoxide containing streams produced by gasifying solid carbonaceous feedstock and steam reforming of light fossil fuels. The gasifier syngas is treated to preferentially remove at least 99% of sulfur containing impurities and less than 50% of the CO₂ to produce a treated gasifier syngas and a CO₂ enriched gas. The treated gasifier syngas and the light fossil fuel conversion unit product gas are combined to form a mixed syngas that is converted into a liquid fuel product. The CO₂ enriched gas is used in the gasification unit.

A modified water-immiscible solvent useful in the extraction of acetic acid from aqueous streams is a substantially pure mixture of isomers of highly branched di-alkyl amines. This solvent is substantially devoid of mono-alkyl amines and alcohols. Solvent mixtures formed of such a modified solvent with a desired cosolvent, preferably a low boiling hydrocarbon which forms an azeotrope with water are useful in the extraction of acetic acid from aqueous gaseous streams. An anaerobic microbial fermentation process for the production of acetic acid employs such solvents, under conditions which limit amide formation by the solvent and thus increase the efficiency of acetic acid recovery. Methods for the direct extraction of acetic acid and the extractive fermentation of acetic acid also employ the modified solvents and increase efficiency of acetic acid production. Such increases in efficiency are also obtained where the energy source for the microbial fermentation contains carbon dioxide and the method includes a carbon dioxide stripping step prior to extraction of acetic acid in solvent.

The present invention further relates to improved processes for preparing lenalidomide crystalline form A, use of said crystalline form A as an active pharmaceutical ingredient or as an intermediate in the preparation of further crystalline or amorphous forms of lenalidomide, compositions comprising lenalidomide crystalline form A and their use in the treatment of disease.

A steam-assisted gravity drainage method includes a two stage solvent injection scheme, wherein steam plus solvent injection is followed by steam plus heavier-solvent injection. The two solvent injections improve recoveries of both the heavy oil and the injected solvent while limiting steam requirements, thus improving the economics of the method.

A method of forming carbon nanotube-polymer composites includes the steps of forming a mixture solution including a plurality of carbon nanotubes dispersed in a co-solvent. The co-solvent includes an organic solvent and a second solvent being a short chain fluorinated carboxylic acid having a boiling point below 150° C. which is less oxidizing than nitric acid, and is soluble in both the organic solvent and water. The first polymer is mixed with the mixture solution to form a polymer including mixture. The co-solvent is removed from the polymer mixture to form a dispersed nanotube-polymer composite. The second solvent can be trifluoroacetic acid.

An apparatus and process is provided for improved asphaltene separation from heavy hydrocarbon or bitumen with low process complexity through mass transfer using solvent and counter-current flows, with three sections: an upper DAO/solid-asphaltene separation zone, a middle solvent mixing and segregation zone, and a bottom clarification zone. Solvent mixed with heavy hydrocarbon forms a process feed introduced to the process vessel's upper zone and exposed to counter-current solvent removing DAO from solid asphaltene particles in the feed, the particles fall through the middle zone and are mixed with introduced solvent, which introduced solvent segregates DAO-rich solution in the upper zone (for extraction from that zone) from solvent-rich mixtures in the middle mixing and lower clarification zones. Solvent flows and precipitate movement are controlled to optimize mass transfer in process, resulting in high DAO recovery and dry, solid asphaltene product.

The present invention relates to the use of a branched addition copolymer in combination with a polymer in a solution or melt formulation to reduce the viscosity of the solution formulation and/or melt formulation compared to the viscosity of a solution and/or melt comprising the polymer alone wherein the branched addition copolymer is obtainable by an addition polymerisation process, methods for the preparation of the formulations, and novel branched addition copolymers for use as same.

A photoresist coating system and method solving an edge bead problem that occurs in photoresist coating by adding at least one of high boiling point solvent, which may generate a film on the surface of a solvent having a higher boiling point than a solvent contained in a liquid photoresist or the surface of the liquid photoresist, or by supplying a surfactant to an edge of the wafer, with the surfactant being combinable with the solvent or capable of forming a film on the solvent.

Δ9 THC is obtained by extracting Δ9 THC and Δ9 THC carboxylic acid from plant material using a non-polar solvent and decarboxylating the Δ9 THC acid into Δ9 THC in the same solvent, without a solvent swap, in the presence of aqueous base. The Δ9 THC is then washed to remove inorganic impurities, still in the same original solvent.

Accelerated dechlorination of soil and water contaminated with chlorinated solvents in situ is achieved by delivering ferric ammonium citrate into the soils and/or water. The induction of ferric ammonium citrate into sulfate-rich reducing conditions initiates a combined abiotic and biotic mechanism for the dechlorination of subsurface contaminants. Initial and rapid removal of chlorinated solvents is achieved by way of reductive transformation, a mechanism utilizing the creation of an iron-bound soil mineral (pyrite) followed by stimulating conditions for enhanced biological natural attenuation.
