China, which is the highest coal consumption nation, has promoted large coal gasification projects to obtain the highly efficient clean energy. Many coal gasification plants have been constructed in China by using foreign gasification technologies since 1980 whereas China attempted to develop its own gasification technology due to problems in operation through their applications. The representative among China"s coal gasification technologies is OMB (Opposed Multi Burner) CWS and SE (Sinopec+ECUST) entrained-flow gasification technology of ECUST-ICCT. Pilot scale gasifier has been studied from 1995 and then 3000 ton/day commercial gasifier was developed in 2015. 44 gasification projects using ECUST technology are conducted. 121 gasifiers are operated or under construction and development in those projects. In particular, OMB CWS gasifiers of 2500 ton/day (×5) have been planned for construction in Valero Energy in Texas, USA in order to produce H2. In this paper, we would like to introduce status of China ECUST-ICCT gasification technology and find current issues in developing Korean gasification technology.
