A holistic hydrocarbon reforming analysis is performed using equilibrium calculations based on Gibbs energy minimization. The feed composition defined the oxygen to carbon atom ratio and hydrogen ratio. coke formation, dioxide yield, synthesis gas mole fraction were investigated determine an operating region for while monoxide ratio, stoichiometric produce optimal compositions downstream proces...
Alcohol oxidase (AO) is the key enzyme of methanol metabolism in methylotrophic yeast species. It catalyses the first step of methanol catabolism, namely its oxidation to formaldehyde with concomitant production of hydrogen peroxide. In its mature active form, AO is a molecule of high molecular mass (600 kDa) that consists of eight identical subunits, each of which carry one non-covalently boun...
The use of zeolite catalysts for the refining of products from methanol synthesis and Fisher-Tropsch synthesis was reviewed. The focus was on fuels refining processes and differences in the application to indirect liquefaction products was compared to petroleum, which is often a case of managing different molecules. Processes covered were skeletal isomerisation of n-butenes, hydroisomerisation ...
Methanol synthesis via catalytic CO2 hydrogenation is an important reaction where a valuable fuel and chemical produced from greenhouse gas. In2O3- Pd-promoted In2O3 have experimentally shown promising activity selectivity, although the nature of active sites remains under debate. In this study, kinetic behavior potential in toward methanol competing reverse water–gas shift assessed by explorin...
In the investigation, modeling of facility for methanol synthesis was carried out under conditions replacement catalyst. The process model compiled using DWSim software package. Based on calculations, possibility working high-pressure plant with a low-temperature catalyst evaluated
The article presents a plasma chemical technology for processing solid fuels, using examples of bituminous and brown coals. Thermodynamic and experimental investigation of the technology was made. The technology allows producing synthesis gas from the coal organic mass and valuable components (technical silicon, ferrosilicon, aluminum, and carbon silicon, as well as microelements of rare metals...
