Abstract
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.
