Abstract:
Fuel production and development of new routes to base chemicals from renewable resources are currently drawing much attention worldwide. The production of synthesis gas (CO + H2), e.g., from biomass-derived feedstock and its conversion to methanol, dimethyl ether (DME), or gasoline provides an attractive option. Recently, DME has attracted a lot of interest not only as liquefied petroleum gas for domestic applications and intermediate product for various base chemicals but also as a clean diesel substitute. Traditionally, DME is obtained in a two-step process, where methanol is produced from syngas with a Cu-based catalyst in the first stage, followed by methanol dehydration to DME with an acidic catalyst in the second stage. Alternatively, methanol synthesis is coupled in situ with the condensation to DME and immediately removed from the equilibrium in the single-step, syngas-to-DME (STD) process. The STD process has several advantages, e.g. the reduction of investment costs and a lower optimum CO/H 2 ratio, which favors the use of biomass-derived syngas. The design of STD catalysts remains a crucial issue for enhancing the catalyt ... mehr
