    摘要： Processes for converting ethanol and syngas (CO and H2) to isobutanol are disclosed. Syngas and ethanol are reacted in the first reaction zone in the presence of a first heterogeneous catalyst to produce a first reactor effluent comprising a first mixture of alcohols. The first reactor effluent is reacted a second reaction zone in the presence of a second heterogeneous catalyst to produce a second reactor effluent comprising a second mixture of alcohols. The second reactor effluent is separated into an overhead gas stream and a liquid bottom stream. The liquid bottom stream is separated into at least a C1-2 stream, a C3 stream, and a C4+ stream. The isobutanol is recovered from the C4+ stream.

    摘要： The invention provides a process for the separation of a diol from a product stream. The process includes the steps of: i) separating the product stream comprising three or more C2 to C6 diols, C3 to C6 sugar alcohols, and C4 to C6 polyhydric alcohols with at least 3 hydroxyl groups in the molecule, and a catalyst, to produce a first stream comprising the three or more C2 to C6 diols; ii) separating the first stream comprising the three or more C2 to C6 diols into a) a second stream comprising a first diol and unsaturated hydrocarbons and/or one or more compounds with a carbonyl group and b) a third stream comprising two or more diols; iii) hydrogenating the second stream comprising a first diol and unsaturated hydrocarbons and/or one or more compounds with a carbonyl group to provide a purified diol stream.

    摘要： A process for preparing 1,2-propanediol involves dehydrogenating propane to provide a product stream containing propane, propene, and hydrogen; and separating the product stream into a stream containing essentially hydrogen, a stream enriched in propane, and a stream enriched in propene. The process then involves reacting the stream containing essentially hydrogen with oxygen to provide a stream containing hydrogen peroxide; and reacting the stream enriched in propene with the stream containing hydrogen peroxide in the presence of a catalyst mixture, containing a phase transfer catalyst and a heteropolytungstate, in a reaction mixture with two liquid phases. The process further involves separating the reaction mixture of the propene oxidation into an aqueous phase and an organic phase, recycling the organic phase to the propene oxidation, and separating 1,2-propanediol from the aqueous phase.
