Methane Autothermal Reforming Reactor.
Methane autothermal reforming (ATR) is a process for converting methane into synthesis gas, a mixture of hydrogen and carbon monoxide. The process is typically carried out in a reactor that consists of a packed bed of catalyst particles. The catalyst is typically a nickel-based catalyst supported on a ceramic material. The methane feedstock is mixed with air or oxygen and preheated before entering the reactor. The reaction is exothermic, so the heat generated by the reaction is used to preheat the feedstock. The products of the reaction are synthesis gas, water, and carbon dioxide.
The design of the ATR reactor is critical to the efficiency of the process. The reactor must be able to provide a uniform distribution of the reactants over the
catalyst surface, and it must be able to remove the heat generated by the reaction. The reactor must also be able to withstand the high temperatures and pressures that are required for the reaction to occur.
There are a number of different reactor designs that can be used for ATR. The most common type of reactor is the shell-and-tube reactor. In this type of reactor, the catalyst particles are packed into a tube, and the reactants are passed through the tube. The heat generated by the reaction is removed by cooling water that flows through the shell of the reactor.
Another type of reactor that is used for ATR is the fluidized bed reactor. In this type of reactor, the
catalyst particles are fluidized by a stream of gas. The reactants are passed through the fluidized bed of catalyst particles, and the heat generated by the reaction is removed by the gas stream.
The design of the ATR reactor is a critical factor in the efficiency of the process. The reactor must be able to
provide a uniform distribution of the reactants over the catalyst surface, and it must be able to remove the heat generated by the reaction. The reactor must also be able to withstand the high temperatures and pressures that are required for the reaction to occur.
