Red Leaf Resources, Inc, is an oil-shale company based in Salt Lake City, Utah, United States. It is a developer of the shale oil extraction technology EcoShale In-Capsule Process. The company is affiliated with Questerre Energy.〔 〕 ==Technology== In the Red Leaf Resources EcoShale In-Capsule Process a hot gas is generated by burning natural gas or pyrolysis gas. Generated hot gas is then circulated through oil shale rubble using sets of parallel pipes. The heat is transferred to the shale through the pipe walls rather than being injected directly into the rubble, thereby avoiding dilution of the product hydrocarbons with the heating gas. The oil shale rubble is enclosed by a low-cost earthen impoundment structure to prevent environmental contamination and to provide easier and more rapid reclamation after the extraction process is finished. Heat from the spent shale is recovered for enhancing the process's energy efficiency by passing cool gas through pipes and then using it for preheating adjacent capsules.〔 〕〔 〕 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「Red Leaf Resources」の詳細全文を読む スポンサード リンク
