Title: Dimethyl ether production from methanol and/or syngas

Abstract

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.

Development of alternative fuels from coal derived syngas. Topical report: Task 2.2, Demonstration of a one-step slurry-phase process for the production of dimethyl ether/methanol mixtures at the LaPorte Alternative Fuels Development Unit

Technical Report

This report documents engineering, modification, and operations efforts of demonstration of dimethyl-ether/methanol coproduction in a slurry-phase reactor, carried out in a 2-ft diameter bubble column reactor. Equipment modifications made it possible to remove the product DME and by-product CO{sub 2} from the reactor effluent. Coproduction of dimethyl-ether (DME) and methanol (MeOH) was accomplished in the slurry reactor by physically mixing two different catalysts. The catalyst used to produce MeOH from syngas was manufactured by BASF (type S3-86); the catalyst used to convert MeOH to DME was Catapal {gamma}-alumina. Ratio of MeOH to DME catalysts determined the selectivity towards DME. Themore »« less

High-Octane Gasoline from Lignocellulosic Biomass via Syngas and Methanol/Dimethyl Ether Intermediates: 2020 State of Technology

Technical Report Harris, Kylee; Ruddy, Daniel; Nash, Connor; ...

The 2020 state of technology (SOT) serves as an update to the 2019 SOT report and details the techno-economic analysis (TEA) results for producing high-octane gasoline (HOG) via indirect liquefaction (IDL). This report only describes changes to the experimental and analysis results from previous SOTs; more details regarding the full process design can be found in the 2015 design report. The conversion pathway presented in this report includes the gasification of biomass, steam reforming and cleanup of the syngas, followed by the conversion of the syngas to HOG via methanol and dimethyl-ether (DME) intermediates. Research efforts in 2020 included themore »« less

Synthesis of dimethyl ether and alternative fuels in the liquid phase from coal-derived syngas; Quarterly technical progress report No. 2, 1 April--30 June 1990

Technical Report

Contract objectives are: development of a one-step liquid phase dimethyl ether/methanol process; and investigation of the potential of liquid phase synthesis of alternative fuels from coal-derived synthesis gas. In the one-step liquid phase Dimethyl Ether (DME) program, the optimum ratio of methanol synthesis catalyst to DME forming catalyst is forming 4.3 to 1 under reaction conditions of 250{degrees}C and 750 psig. At a commercially significant space velocity of 6000 sl/kg-hr, the methanol equivalent productivity is 50% higher than that for methanol synthesis alone. Using Shell gas instead of ``CO-rich`` (Texaco) gas leads to lower DME productivity due to the lowermore »« less
Synthesis of methanol and dimethyl ether from syngas over Pd/ZnO/Al2O3 catalysts

Journal Article Lebarbier, Vanessa; Dagle, Robert; Kovarik, Libor; ... - Catalysis Science and Technology

A Pd/ZnO/Al2O3 catalyst was developed for the synthesis of methanol and dimethyl ether (DME) from syngas. Studied were temperatures of operation ranging from 250°C to 380°C. High temperatures (e.g. 380°C) are necessary when combining methanol and DME synthesis with a methanol to gasoline (MTG) process in a single reactor bed. A commercial Cu/ZnO/Al2O3 catalyst, utilized industrially for the synthesis of methanol at 220-280°C, suffers from a rapid deactivation when the reaction is conducted at high temperature (>320°C). On the contrary, a Pd/ZnO/Al2O3 catalyst was found to be highly stable for methanol and DME synthesis at 380°C. The Pd/ZnO/Al2O3 catalyst wasmore »« less

Single-Step Syngas-to-Distillates (S2D) Synthesis via Methanol and Dimethyl Ether Intermediates: Final Report

Technical Report Dagle, Robert; Lebarbier, Vanessa; Lizarazo Adarme, Jair; ...

The objective of the work was to enhance price-competitive, synthesis gas (syngas)-based production of transportation fuels that are directly compatible with the existing vehicle fleet (i.e., vehicles fueled by gasoline, diesel, jet fuel, etc.). To accomplish this, modifications to the traditional methanol-to-gasoline (MTG) process were investigated. In this study, we investigated direct conversion of syngas to distillates using methanol and dimethyl ether intermediates. For this application, a Pd/ZnO/Al2O3 (PdZnAl) catalyst previously developed for methanol steam reforming was evaluated. The PdZnAl catalyst was shown to be far superior to a conventional copper-based methanol catalyst when operated at relatively high temperatures (i.e.,more »« less
