A new preparation scheme for a difficult-to-float coking coal by column flotation following grinding
Abstract In this study, the composition of tars collected during a six-day underground coal gasification (UCG) test at experimental mine ‘Barbara’ in Poland 2013 was examined. During test, tar samples were taken every day from liquid product separator and analysed by methods used for testing properties typical coke oven (coal) tar. The obtained results compared with each other data As progresse...
A Mo-modified H-MFI zeolite (Mo/H-MFI) catalyst is one of a typical catalyst for direct GTL (Gas to liquid), because it shows high activity for dehydroaromatization of methane in absence of oxygen. In this reaction, reduction of Mo species is brought about in contact with methane in initial step, and reduced Mo ions react methane to form carbide and/or oxycarbide species in next step. It has be...
Ordered, extra-large mesopores with highly loaded gold nanoparticles (AuNPs) exhibits unique sintering- and coking-resistant properties in gas-phase, cyclohexanol selective aerobic oxidation.
Phenol and phenolic compounds are environmental pollutants present in industrial wastewaters such as coal tar, oil refineries and petrochemical plants. Phenol removal from industrial effluents is extremely important for the protection of environment. Usually, phenol degradation is carried out by physicochemical methods that are costly and produce hazardous metabolites. Recently, phenol biodegra...
Xishan mining area in Taiyuan is a typical coal industry cluster with variety of coal-related industrial sites such as mines, power plants and coking plants, which seriously pollute the native ecological environment. Study hydrochemical characteristics pollution sources groundwater can contribute to protection remediation regional resources. In this study, we collected surface water samples fro...
