People are looking for more efficient use of the source in recent years due to the rapid depletion in the fossil fuel resources. Gasification of coal is a useful method for produce clean and efficient energy. This study was carried out to find out the various trends in scientific studies that provide literature for the field of coal gasification on world. All data used in this study have been reached from Web of Science database. In this study, the coal gasification related to both bibliometric and historical analyses were investigated. The Web of Science database was scanned for the articles about coal gasification between the years of 1989 and 2020. The considered parameters in the bibliometric analysis are the number of citations and documents, authorships and ownerships, patterns of international collaborations and addresses.
