Development of Thermal Cracking Liquefaction Process for Plastic Waste

摘要

To liquefy municipal plastic waste inexpensively, we developed thermal cracking process using hot sand. The features of this process are an availability for foreign materials with plastic waste and a stable operability. We constructed a demonstration plant with a capacity of 5 ton per day. The test results attained a liquefaction yield of 0.58 l-oil/kg-feed and we confirmed the principle of this new process. To design commercial plant, it is necessary to study scale up methodology of reactor and improve operability of recovered oil handling system. We will study to expand an application of the recovered oil in order to enhance a feasibility of this process.
