This invention relates to a process for transforming methanol to aromatic hydrocarbons, comprising: use methanol as raw material, with modified ZSM-5 molecular sieve as catalyst, under conditions of operation pressure 0.1-5.0Mpa, operation temperature 300-460Deg C, raw material liquid air speed 0.1-6.0h-1, transformed to products with aromatic hydrocarbons as main components; separate the gas-phase products lower carbon hydrocarbons from the liquid-phase C5+ hydrocarbons by cooling separation; the liquid-phase C5+ hydrocarbons then can be separated to be aromatic hydrocarbons and non-aromatic hydrocarbons by extracting separation. This invention is characterized of high total selectivity of aromatic hydrocarbons and flexible process operation.

A process for preparing dimethylbenzene by aromatization of methanol relates to a process for preparing dimethylbenzene by conducting aromatization reaction in a methanol aromatization reactor with methanol and hydrocarbon as raw materials. The process uses a metal-modified molecular sieve composite material as catalyst and causes the mixture of methanol and one or a plurality of C1-C12 hydrocarbons to conduct aromatization reaction in the methanol aromatization reactor. By adjusting the ratio between methanol and hydrocarbons in the raw material, the process regulates and controls the coordination between aromatization and alkylation reaction and realizes the purposes of effectively improving the yield of the target product dimethylbenzene and prolonging the service cycle of catalyst.

A method was developed to prepare silk fibroin microspheres using lipid vesicles as templates to efficiently load therapeutic agents in active form for controlled release. The lipids are subsequently removed through the use of a dehydration agent, such as methanol or sodium chloride, resulting in β-sheet structure dominant silk microsphere structures having about 2 μm in diameter. The therapeutic agent can be entrapped in the silk microspheres and used in pharmaceutical formulations for controlled-release treatments.

A system involving a two-step gasification of a carbonaceous source to produce bulk hydrogen that avoids the early formation of CO₂ and obviates the traditional water gas shift (WGSR) step, carbochlorination of a metallic ore the production of metals found in the ore that utilizes carbon monoxide as an oxygen sink, rather than the traditional coke, and carbon oxides management that eliminates major impediments to emission-neutral power generation and the reduction of major metals. The gasification uses a rotary kiln reactor and gas-gas cyclonic separation process to separate synthesis gas into purified hydrogen and purified carbon monoxide. Purified bulk carbon monoxide issued in metallurgical reduction, and purified bulk hydrogen as fuel for an emission-neutral hydrogen combined cycle (HCC) turbine power generation station. The carbochlorination is integrated with: a) the concurrent separation and purification of all metal-chlorides (metchlors) and capture of CO₂ for passage to the carbon oxides management system; b) the direct reduction of metchlors to nanoscale metallurgical powders and/or to dendritically-shaped particles, including metchlor reduction for the ultrahigh-performance semiconductor metals of the III-V group; and, c) the reforming of metal-oxides with improved crystalline structure from metchlors. The carbon oxides management collects, stores and directs to points of usage, carbon oxides that arise in various processes of the integrated system, and captures carbon monoxide for process enhancement and economic uses and captures carbon dioxide as a process intermediate and for economic uses.

A methanol carbonylation system 10 includes an absorber tower 75 adapted for receiving a vent gas stream and removing methyl iodide therefrom with a scrubber solvent, the absorber tower being coupled to first and second scrubber solvent sources 16, 56 which are capable of supplying different first and second scrubber solvents. A switching system including valves 90, 92, 94, 96, 98 alternatively provides first or second scrubber solvents to the absorber tower and returns the used solvent and sorbed material to the carbonylation system to accommodate different operating modes.

An environmentally beneficial method of producing methanol from varied sources of carbon dioxide including flue gases of fossil fuel burning power plants, industrial exhaust gases or the atmosphere itself. Converting carbon dioxide by an electrochemical reduction of carbon dioxide in a divided electrochemical cell that includes an anode in one cell compartment and a metal cathode electrode in another cell compartment that also contains an aqueous solution comprising methanol and an electrolyte of one or more alkyl ammonium halides, alkali carbonates or combinations thereof to produce therein a reaction mixture containing carbon monoxide and hydrogen which can be subsequently used to produce methanol while also producing oxygen in the cell at the anode.

The invention relates to a manufacturing mode of environment-friendly and energy-saving M15_M85 methanol diesel oil. The methanol diesel oil is composed of diesel oil, methanol, and additives. The methanol diesel oil is prepared with operations under normal temperatures and normal pressures. The invention discloses a plurality of common additives used for preparing methanol diesel oil in modern times. If explosives and aviation fuels are appropriately utilized, methanol defalcated heat value can be well compensated. The theory is tentatively considered as a gaseous detonation theory. The additives can be selected from nitric acid esters, nitrates, nitro compounds, non-aromatic compounds, peroxides, and the like.
