Translated from Nensho no Kagaku to Gijutsu, 3, 255-264 (1996) - Basic studies on gasification characteristics of organic model wastes
Plastic waste is increasing every year. Gasification is one of many chemical recycling technologies. The authors carried out basic gasification tests on polyethylene. To produce a tar and soot free synthetic gas composed mainly of hydrogen and carbon monoxide which is a feed source for methanol fuel production, polyethylene pellets are gasified in the presence of oxygen and steam. The first step of the gasification process produces a soot-free gas with "tar", the second step of the gasification process decomposes the "tar" produced in the first step. As a result, this closed, coupled two step gasification process has proven to be a tar and soot free gasification technology for plastic wastes.
