Ze-gen, Inc. is a renewable energy company developing advanced gasification technology to convert waste into synthesis gas. Founded in 2004, Ze-gen is a venture-backed company based in Boston, Massachusetts. The company aims to develop innovative technological solutions to reduce landfills and find beneficial use for waste material by converting waste-to-energy and nutrients, using advanced gasification in a way that reduces environmental degradation. ==Technology== The ''liquid metal gasification'' process begins with feed material entering the gasifier through a gas-tight airlock into a refractory-lined vessel containing liquid copper, which is held at about 2200 °F. Material entering into the liquid metal gasifier undergoes a series of thermo-chemical reactions, which are auto-thermal under stable operating conditions. Initially, pyrolysis occurs and volatiles are driven into the headspace of the gasifier. In the subsequent gasification reaction, hydrogen () and carbon monoxide (CO) are favored as final products, along with carbon dioxide () and a small amount of methane (). This product gas is called synthesis gas, also known as syngas. The inorganic constituents, which are generally lighter than liquid metal, form a slag layer on top of the liquid metal bath and are removed as a vitrified non-leachable slag byproduct. The slag is either recycled or disposed of as an industrial by-product. While some metals and oxides present in the feedstock accumulate in the liquid metal bath, others will exit as vapor and are captured in the gas cleanup process. The syngas produced can be used for several different end-use applications including: steam generation, electricity production, making industrial hydrogen gas, as chemical building blocks for synthetic diesel or ethanol, synthetic natural gas, methanol, or as a chemical feedstock into a variety of industrial processes. 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「Ze-gen」の詳細全文を読む スポンサード リンク
