Catalytic Reforming - an overview ScienceDirect Topics

WebThe primary reformer is a typical steam methane reformer, and the secondary reformer is an autothermal reformer. Both reforming routes are governed by the steam reforming and water-gas shift reactions shown in Eqs. (1) and (2). The primary reformer operates at 40 bar and three discrete temperatures (800 °C, 850 °C, and 900 °C). WebChemical looping reforming (CLR) utilizes the same basic principles as CLC. CLR could be described as a process for the partial oxidation of hydrocarbon fuels (rather than complete oxidation as in CLC), where a solid oxygen carrier is used as a source of undiluted oxygen. A methane reformer is a device based on steam reforming, autothermal reforming or partial oxidation and is a type of chemical synthesis which can produce pure hydrogen gas from methane using a catalyst. There are multiple types of reformers in development but the most common in industry are autothermal reforming (ATR) and steam methane reforming (SMR). Most methods work by exposing methane to a catalyst (usually nickel) at high temperature and pressure. flying friends flyers choice birdseed
