In homogeneous catalysis, the catalyst is in the same phase as the reactant. The number of collisions between reactants and catalyst is at a maximum.In a patent, 1941-30-6, name is Tetrapropylammonium bromide, introducing its new discovery. Quality Control of: Tetrapropylammonium bromide
Methanol to clean gasoline over nanostructured CuO-ZnO/HZSM-5 catalyst: Influence of conventional and ultrasound assisted co-impregnation synthesis on catalytic properties and performance
In current paper, the catalytic conversion of methanol to gasoline range hydrocarbons has been studied over CuO(7%)-ZnO(5%)/HZSM-5(Si/Al = 65) catalysts prepared via conventional co-impregnation and ultrasonic methods. The samples were characterized by XRD, FESEM, BET, EDX, TEM and FTIR techniques. Characterizations proved smaller crystal size, more specific surface area and more uniform dispersion for the ultrasonic-assisted synthesized sample. Also, the performance test was done and ultrasonic-assisted synthesized catalyst showed 25% more selectivity to aromatics and 14% more selectivity to octanes and it has more potential to produce desirable products for gasoline cut.
The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 1941-30-6 is helpful to your research. Quality Control of: Tetrapropylammonium bromide
