Co-gasification of coal and plastic-waste simulated sample (PP) by 3 TPD gasifier

Abstract

CRIEPI is developing a poly-generation system using various fuels with CO₂ capture. The system is composed of a gasifier, a gas clean-up, a power generation, and a chemical synthesis process. The gasifier is based on an O₂/CO₂/H₂O blown gasifier developed in a previous project for developing an Oxy-fuel IGCC system, and it will be upgraded in the present project to treat various carbonaceous feedstock, such as plastic wastes as well as coal. This presentation shows the current progress of the research project, especially about 3 TPD gasifier test results. Coal and polypropylene (PP) as a plastic-waste simulated sample were co-gasified by the 3 TPD gasifier. In the case of polypropylene injection into the combustor, organic gas concentration in syngas was suppressed compared with the case of its injection into the reductor.
