The present disclosure relates to a method that includes converting a gas stream that contains hydrogen (H) and carbon monoxide (CO) to a second mixture that contains a hydrocarbon, for example, a hydrocarbon having between 3 and 15 carbon atoms, where the converting is performed using a first catalyst configured to convert Hand CO to methanol, a second catalyst configured to convert methanol to dimethyl ether (DME), and a third catalyst configured to convert DME to the hydrocarbon.

Methods, systems, and catalysts for the direct conversion of syngas to high-octane hydrocarbons

The present disclosure relates to a mixture that includes a first portion that includes at least one of a paraffin and/or a naphthene having between 5 carbons and 13 carbons, inclusively, at a first concentration between about 75 wt % and about 99 wt %, and a second portion that includes hydrocarbons having greater than 13 carbons at a second concentration of less than 0.05 wt %.

High octane synthetic fuels

Catalysts and processes designed to convert DME and/or methanol and hydrogen (H) to desirable liquid fuels are described. These catalysts produce the fuels efficiently and with a high selectivity and yield, and reduce the formation of aromatic hydrocarbons by incorporating Hinto the products. Also described are process methods to further upgrade these fuels to higher molecular weight liquid fuel mixtures, which have physical properties comparable with current commercially used liquid fuels.

Catalysts and methods for converting carbonaceous materials to fuels

This disclosure relates to catalysts and processes designed to convert DME and/or methanol and hydrogen (H) to desirable liquid fuels. These catalysts produce the fuels efficiently and with a high selectivity and yield, and reduce the formation of aromatic hydrocarbons by incorporating Hinto the products. This disclosure also describes process methods to further upgrade these fuels to higher molecular weight liquid fuel mixtures, which have physical properties comparable with current commercially used liquid fuels.

The invention herein provides methods of activating a catalyst composition. These methods include annealing a catalyst with an inert gas, under effective conditions, and then contacting the annealed catalyst with syngas to produce an activated catalyst. These steps can also be reversed. The activated catalysts can be employed to convert syngas into products, such as alcohols, with improved selectivities and yields.

Methods for improving syngas-to-alcohol catalyst activity and selectivity

The disclosed invention provides methods and apparatus for producing one or more C-Calcohols (such as ethanol) from syngas, while simultaneously removing CO, thereby providing low COyields. The present invention provides reactors for producing one or more C-Calcohols from syngas, the reactors containing a first composition capable of catalyzing the conversion of syngas to C-Calcohols under reaction conditions and a second composition capable of (a) adsorbing COunder the reaction conditions and then (b) releasing at least some of the COunder different regeneration conditions.
