Cu/SiO2 catalysts for methanol to methyl formate dehydrogenation

Catalytic oxidation of methanol to methyl formate over silver ? a new purpose of a traditional catalysis system

“…It has been introduced that the short lifetime is the usually shortcoming for the copper-based catalysts [8], so the lifetime test was also performed over the silver catalyst. The fresh silver catalyst was pretreated in air flow (10 mL min )1 ) at 573 K for 180 min.…”

“…The catalytic activity and selectivity to methyl formate of these catalysts are strongly affected by the preparation and activation methods, as the formation of methyl formate is sensitive to the structure of active sites [8]. Hence, most copper-based catalysts are not stable enough because of the congregation of copper atoms, the polymerization of formaldehyde on active sites, and the coking on active sites.…”

Catalytic Oxidation of Liquid Methanol as a Heat Source for an Automotive Reformer

“…The catalysts were prepared using wet impregnation [10]. The metallic precursors were all in the form of nitrates, with the exception of the platinum precursor where platinum (II) 2,4-pentanedionate was used.…”

Methanol to Long-chain Oxygenates Over Mg/Al Mixed Oxides Supported Cu Catalysts

“…It can be used as a direct fuel for fuel cells, i.e., DMFCs (direct methanol fuel cells), as an additive to current fuels, or as a feedstock to produce hydrogen, biodiesels, chemicals such as acetic acid [1], or other fuel additives or substitutes such as methyl tertiary butyl ether (MTBE) [2,3], methyl formate (MF) [4,5], dimethyl ether (DME) [6,7], etc. Furthermore, existing processes can produce long-chain chemicals from methanol, e.g., the methanol-to-gasoline (MTG) [8][9][10], the methanol-to-olefins (MTO) [11][12][13], or the methanol-to-hydrocarbons (MTH) processes [14][15][16][17][18][19].…”
