C1 Coupling via bromine activation and tandem catalytic condensation and neutralization over CaO/zeolite composites.
نویسندگان
چکیده
We demonstrate here an alternative scheme for C(1) coupling by way of methane bromination, followed by concurrent bromomethane condensation and quantitative HBr neutralization; regeneration of the metal oxide with O(2) with recovery of Br(2) completes the cycle.

C1 oxidative coupling via bromine activation and tandem catalytic condensation and neutralization over CaO/zeolite composites II. Product distribution variation and full bromine confinement
We describe a three-step bromine-mediated process for oxidative coupling of methane using O2 as oxidant. In the first step, a supported metal bromide solid is treated with O2 to generate Br2 and supported metal oxide. The Br2 thus formed reacts with excess CH4, giving a mixture of CH4, bromomethanes, and HBr. This mixture is passed over a CaO/zeolite composite which condenses bromocarbons with ...
متن کاملThermal and catalytic degradation study of polyethylene and investigation the catalytic effect of X-Zeolite and Silica-Alumina on degradation kinetic
The thermal degradation of polyethylene (PE) was carried out in the absence and presence ofcatalystes X-Zeolite and Silica-Alumina at different temperatures. The optimum PE/Catalysisratio was 0.25:0.05 g/g, which produced highest degradation value. PE and PE/Catalysis werecharacterized by thermogravimetric analysis. The thermal degradation properties of polymerhave been studied by Infrared spec...
متن کاملSelective Catalytic Reduction of CuO/SiO2 Nano-composites towards NO Reduction in Gas-phase
The xerogel samples were prepared by hydrolysis and condensation of tetraethyl orthosilicate (TEOS) by the sol-gel method. In this investigation, a new molar ratio of H2O/TEOS was determined to be 11.7. Also, the necessary amounts of tri-hydrated copper nitrate and penta-hydrated copper sulfate were added to the solution in such a manner that the concentration of the copper oxide in final solut...

Ni/Al-HMS/HZSM-5 catalysts with varying amounts of Si/Al ratios were prepared via the impregnation method and evaluated for the hydrogenation of benzene at 130−190 °C. To study the catalyst characterization, various methods were used as X-ray diffraction, X-ray fluorescence, Fourier transform infrared spectroscopy, ultraviolet-visible diffuse reflectance spectroscopy, temperature-programmed des...
