Direct Nonoxidative Methane Coupling to Ethylene over Gallium Nitride: A Catalyst Regeneration Study
Publikováno v:
Industrial & Engineering Chemistry Research. 59:4245-4256
The abundance of methane in natural and shale gases creates the need to develop processes for the direct conversion of methane to olefins, aromatics, and hydrogen. In this work, the regeneration ca...

The direct non-oxidative methane aromatization over commercially available gallium nitride powder has been investigated for the first time in a fixed bed reactor under continuous operation. Gallium nitride catalyst is highly active. High reaction tem

TG experiments and DFT calculations were used to investigate the mechanism of gallium oxide nitridation to gallium nitride. The overall conversion of the gas-solid reaction can be best described by a modified integrated model that accounts for diffus

Vast availability of natural and shale gases makes methane a reliable source for synthesizing valuable chemical building blocks such as ethylene. A new stable supported GaN/SBA15 catalyst from an emerging class of nitride catalysts was reported for t

Density functional theory (DFT) was used to study the reaction mechanisms of direct non–oxidative methane (CH4) coupling to ethylene (C2H4) on gallium–based catalysts, GaN ( 1 1 ¯ 00 ) and Ga2O3 (001) surfaces. The adsorption energies of the rea

The dynamics of nanoparticle formation in water-in-oil microemulsions via temporal size evolution has been followed from UV-visible absorption spectra of CdS nanoparticles. Existing Monte Carlo (MC) simulations of nanoparticle formation are primarily

CdS−ZnS core−shell nanoparticles are synthesized in a series of water-in-oil microemulsion solutions with increasing microemulsion drop sizes. Shell formation was confirmed by observation of a red shift in the UV−vis absorption spectra. Nanopar

Modeling the nanoparticle formation mechanism in water-in-oil microemulsion, a self-assembled colloidal template, has been addressed in this paper by two formalisms: the deterministic population balance equation (PBE) model and stochastic Monte Carlo

Rice is one of the most important food crops of India in terms of area, production and consumer preference. India is the second largest producer and consumer of rice in the world. Trends in global rice consumption largely follow those in global produ
