The TOSCO II process is an above ground retorting technology for shale oil extraction, which uses fine particles of oil shale that are heated in a rotating kiln. The particularity of this process is that it use hot ceramic balls for the heat transfer between the retort and a heater. The process was tested in a 40 tonnes per hour test facility near Parachute, Colorado. ==History== TOSCO II process is a refinement of the Swedish Aspeco process.〔 〕 The Tosco Corporation purchased its patent rights in 1952.〔 In 1956, the Denver Research Institute performed research and development of this technology, including testing of a 24 ton per day pilot plant, which operated until 1966. Later the technology development was continued under Tosco's own directions.〔 〕 In 1964 Tosco, Standard Oil of Ohio, and Cleveland Cliffs Iron Company formed Colony Development, a joint venture company to develop the Colony Shale Oil Project and to commercialize the TOSCO II technology. The project was ended in April 1972.〔 〕 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「TOSCO II process」の詳細全文を読む スポンサード リンク
