Processing of Jakarta's Plastic Waste to Gasoline with Catalytic Fluidized Bed Pyrolysis

Abstract

Around 2400 tons of plastic solid waste (PSW) is accumulated in Jakarta each day which leads to significant environmental problems. PSW recycling is difficult due to its heterogeneity and lower quality of the recycled products. This study shows the optimum route to convert single-use PSW to liquid fuel is via fast pyrolysis process with spent FCC catalyst. Polyethylene, polystyrene, polypropylene, and PVC are converted to lighter hydrocarbon fraction of which consists of C2-C4 gasses, gasoline, and char using circulating fluidized bed pyrolysis at 450oC. Gas and char by-products will be reutilized for heating the reactor. Gasoline range hydrocarbons have moderate octane rating which can be utilized as green fuel blend. This solution reveals one way in realizing responsible production and consumption, sustainable cities and communities, along with affordable and clean energy
