Microbial degradation of organic pollutants in groundwater related to underground coal gasification
Energy Science &Engineering, Volume 7, Issue 5, Page 2098-2111, October 2019., 2019 The relationship between TOC in gas washing water with time degraded by WX and JC at pH = 7, 40°C, and 120 rpm. Two kinds of bacteria with high phenol degradation efficiency, named JC and WX, were isolated and screened from two types of activated sludges, and correspondingly identified as pseudomonas aeruginosa (NCBI number: Z76651) and achromobacter ...

Influence of coal properties on the CO2 adsorption capacity of coal gasification residues
Energy Science &Engineering, Volume 6, Issue 4, Page 321-335, August 2018., 2018 Influence of coal properties and gasification conditions on the adsorption capacities of CO2 on gasified coal chars is investigated. Four coals of diverse rank varying from lignite to bituminous were selected and subjected to CO2 gasification at atmospheric pressure for 10 min at 800, 900, and 1000°C under a low heating rate of 5°C/min. The CO2 storage

Ecotoxicology and Environmental Safety, 2015 The effect of coal rank on the composition and toxicity of water effluents resulting from two underground coal gasification experiments with distinct coal samples (lignite and hard coal) was investigated. A broad range of organic and inorganic parameters was determined in the sampled condensates.
