Ethanol conversion over cesium-doped mono- and bi-cationic aluminum and gallium H3PW12O40 salts

Development of Ga Salt of Molybdophosphoric Acid for Biomass Conversion to Levulinic Acid

“…A correlation between Brønsted acidity and catalytic activity were observed . Recently, Filek et al reported the synthesis of monocationic (GaPW 12 O 40 and AlPW 12 O 40 ) and bicationic (CsGa 0.5 H 0.5 PW 12 O 40 and CsAl 0.5 H 0.5 PW 12 O 40 ) salts of HPW for ethylene and diethyl ether production from ethanol . Kimura et al have reported the inorganic solid acids of Cs salt of 12-tungstophosphoric acid Cs 2.5 H 0.5 PW 12 O 40 as being a better catalyst than H 2 SO 4 , H 3 PW 12 O 40 and p -toluenesulfonic acid .…”

“…Glucose is a monomeric sugar that could be obtained by the hydrolysis of starch/cellulose of plant materials . A wide range of chemicals is produced from glucose. , LA, γ-valerolactone, , and hydroxymethylfurfural (HMF) are examples of such chemicals. LA is prepared by treating cellulosic biomass with acid and could be obtained from a wide range of cellulosic feedstock, such as Cicer arietinum, cotton, Pinus radiata, and sugar cane bagasse .…”

Phosphotungstic acid catalysed bioethylene synthesis under industrially relevant conditions

“…For instance, silica-supported HPW provided ethanol conversion and ethylene selectivity above 90 % at 160 °C, while silica-supported Cs salt of HPW needed higher temperature, i. e., 190 °C, to reach similar values of conversion and selectivity 32 . Several works have reported the good activity of HPW-based catalysts, with a very high selectivity towards ethylene [33][34][35][36] , some of them at temperatures as low as 200 °C 37 . Nonetheless, few data regarding the demonstration of their applicability under relevant industrial conditions can be found in the literature, although they are known to be used in Technip Energies' Hummingbird production technology 38 .…”

Graphitic Carbon Nitride as a Sustainable Catalyst for Selective Ethanol Oxidation

“…Ethanol being a basis for production of value-added chemical compounds allows obtaining a lot of various substances related to large-scale final products and intermediates such as commodity chemicals (hydrogen, ethylene, acetaldehyde (Ac), ethyl acetate, aromatic hydrocarbons, etc. ). − Selective oxidation of bioethanol to produce various products, namely, corresponding aldehyde and acid, ethyl acetate, etc., makes an important contribution to the chemical industry and has recently received considerable attention. , …”
