    摘要： Disclosed are methods for producing dimethyl ether (DME) from methanol and for producing DME directly from syngas, such as syngas from biomass. Also disclosed are apparatus for DME production. The disclosed processes generally function at higher temperatures with lower contact times and at lower pressures than conventional processes so as to produce higher DME yields than do conventional processes. Certain embodiments of the processes are carried out in reactors providing greater surface to volume ratios than the presently used DME reactors. Certain embodiments of the processes are carried out in systems comprising multiple microchannel reactors.

    摘要： The invention includes a method of treating a solid acid catalyst. After exposing the catalyst to a mixture containing a sugar alcohol, the catalyst is washed with an organic solvent and is then exposed to a second reaction mixture. The invention includes a process for production of anhydrosugar alcohol. A solid acid catalyst is provided to convert sugar alcohol in a first sample to an anhydrosugar alcohol. The catalyst is then washed with an organic solvent and is subsequently utilized to expose a second sample. The invention includes a method for selective production of an anhydrosugar. A solid acid catalyst is provided within a reactor and anhydrosugar alcohol is formed by flowing a starting sugar alcohol into the reactor. The acid catalyst is then exposed to an organic solvent which allows a greater amount of additional anhydrosugar to be produced than would occur without exposing the acid catalyst to the organic solvent.

    摘要： The invention includes methods of producing dianhydrosugars. A polyol is reacted in the presence of a first catalyst to form a monocyclic sugar. The monocyclic sugar is transferred to a second reactor where it is converted to a dianhydrosugar alcohol in the presence of a second catalyst. The invention includes a process of forming isosorbide. An initial reaction is conducted at a first temperature in the presence of a solid acid catalyst. The initial reaction involves reacting sorbitol to produce 1,4-sorbitan, 3,6-sorbitan, 2,5-mannitan and 2,5-iditan. Utilizing a second temperature, the 1,4-sorbitan and 3,6-sorbitan are converted to isosorbide. The invention includes a method of purifying isosorbide from a mixture containing isosorbide and at least one additional component. A first distillation removes a first portion of the isosorbide from the mixture. A second distillation is then conducted at a higher temperature to remove a second portion of isosorbide from the mixture.
