TL;DR: In this paper, a review discusses current advances in microbial coal conversion, such as the efforts made to comprehend microbial processes, significant outputs of coal conversion and principle components responsible for coal conversion.
Abstract: Coal, the most primitive fossil fuel, has been exploited for ages, and reserves dictate the economies of many countries. Presently, most energy is generated by direct combustion, raising concerns over global warming. Biological pretreatment of fossil resources and generation of alternative green energy can address the environmental issues associated with global coal utilization. Biological coal treatment can produce industrially important chemicals and bio-methane by employing microorganisms able to depolymerize/degrade coal. This review discusses current advances in microbial coal conversion, such as the efforts made to comprehend microbial processes, significant outputs of coal conversion, principle components responsible for coal conversion, and factors affecting the biological processes to convert coal. Development of these biological processes can be a stepping stone for greener coal; however, integration of multidisciplinary technologies is needed to increase the efficiency of economic coal utilization and production of economically and industrially feasible biomethane.

TL;DR: The steady state design and economic evaluation for coal to synthetic natural gas (SNG) process is rigorously studied, and this study could give a baseline for design and analysis for SNG production in Taiwan or other countries relying on importation of an energy source.
Abstract: The steady state design and economic evaluation for coal to synthetic natural gas (SNG) process is rigorously studied, and this study could give a baseline for design and analysis for SNG production in Taiwan or other countries relying on importation of an energy source. SNG is a product that holds very similar composition and heat value to typical natural gas, and can be used as a replacement in industrial and home usages. Natural gas is an important energy source in Taiwan, with increasing demand year by year. Because over 99% of our energy sources is imported in Taiwan, and because of the advantages of coal over natural gas (lower importation price, great abundance, easier transportation and storage, etc.), the process that converts coal into SNG is expected to benefit Taiwan if the related technology is successfully established. The whole process is divided into several parts, including air separation unit (ASU), gasification, the syngas treating section (water gas-shift reaction, syngas cooling, and ...
