Dimethyl ether (DME) is of great industrial interest due to its use as clean fuel for diesel engines or in combustion cells, as a precursor to other organic compounds, as well as a green aerosol propellant that can effectively replace chloro-fluoro-carbons. Conventionally, high purity DME is synthesized by dehydration of methanol produced from syngas, in a process involving a catalytic fixed-be...

The performance of the single-step and sequential-steps catalytic CO2-hydrogenation to DiMethyl Ether (DME) was systematically analyzed. CuO–ZnO model-catalysts for methanol were synthesized via different methods namely co-precipitation, sequential precipitation precipitation-impregnation precursors. Moreover, co-precipitation co-impregnation applied establish bifunctional structures composed o...

The CO2 hydrogenation to dimethyl ether (DME) is a potentially promising process for efficiently utilizing as renewable and cheap carbon resource. Currently, the one-step heterogeneous catalytic conversion of value-added chemicals exhibits higher efficiency than photocatalytic or electrocatalytic routes. However, typical catalysts DME still suffer from deficient space–time yield stability in in...

The depletion of fossil energy sources and the legislation regarding emission control demand use alternative fuels rapid progression aftertreatment technologies. study dimethyl ether (DME) catalytic oxidation is important in this respect, as DME a promising clean fuel at same time VOC pollutant present tail gases industrial processes. In work, copper ferrite catalysts synthesized via citrate co...

Zeolite catalysts that could allow the efficient synthesis of n-butene, such as 1-butene, trans-2-butene, and cis-2-butene, in dimethyl ether (DME)-to-olefin (DTO) reaction were investigated using a fixed-bed flow reactor. The zeolites characterized by N2 adsorption desorption, X-ray diffraction (XRD), thermogravimetry (TG), NH3 temperature-programmed desorption (NH3-TPD). A screening ten avail...

Liquid fuels like dimethyl-ether (DME), produced from biomass and electricity are crucial for decarbonizing the shipping industry. In this work, production of DME wheat straw through gasification is presented. It was shown how process can be optimized by using 1) two-stage instead one-stage synthesis, 2) partial oxidation gas 3) a hydrogen quench high-temperature reverse water shift reactions. ...

Converting syngas into ethanol (EtOH) is highly attractive but remains challenge. Dimethyl ether (DME) carbonylation with CO to methyl acetate (MA) on zeolite and its further hydrogenation EtOH Cu-based catalyst open a new synthesis route from syngas. In this work, nano-sized ZSM-35 (NZ35) zeolite, possessing abundant active sites porosity short diffusion path, found realize much better activit...

The transition towards a CO2 neutral industry is currently spurring many new developments regarding processes for the conversion of CO2, or CO2-rich streams, into platform molecules such as methanol and dimethyl ether (DME). New give rise to separation challenges, well novel opportunities joint optimization reaction separation. In this context, DME can be performed very efficiently using newly ...
