Underground coal gasification (UCG) is a conversion method that permits resources to be exploited in situ using high-temperature reactions. An understanding of the chemical, mineralogical, and petrographic properties coal, resultant unburned carbon, degasified ash (minerals) UCG zone, fundamental determining rates, gas composition, environmental groundwater risk assessments. This study aims pro...

The study of tar behaviors in underground coal gasification (UCG) is essential for pollution control, system safety and conversion efficiency; however, existing studies have only focused on products without revealing evolution the reaction zone, experimental conditions reported work are far from those real situation. In this work, were studied with a self-developed apparatus to simulate UCG pro...

In recent decades, many countries have shown a growing interest in Underground Coal Gasification (UCG) as potential clean and environmental-friendly means of harnessing coal energy for power generation, production hydrogen, diesel fuel, etc. While Bangladesh may good UCG that can be utilized to alleviate the country's current scarcity, this avenue has remained completely untapped up now. work, ...

This paper presents the possibilities of adapting active mines to generate green energy after their closure using resources and/or infrastructure. For this purpose, firstly, temporal horizon selected in Poland was determined, its basic assumption being analysis current state. In research, 18 mining plants operating within 12 Upper Silesian Coal Basin (USCB) were analyzed. The analyzed belong th...

The Escherichia coli relBE operon encodes a toxin-antitoxin pair, RelE-RelB. RelB can reverse inhibition of protein synthesis by RelE in vivo. We have found that although RelE does not degrade free RNA, it cleaves mRNA in the ribosomal A site with high codon specificity. Among stop codons UAG is cleaved with fast, UAA intermediate and UGA slow rate, while UCG and CAG are cleaved most rapidly am...
