Selection of methaneation reactors for coal-to-natural gas production
Thread Content
Coal-to-natural gas is a current focus in coal chemical industry; there are no technical issues with it. However, when it comes to the choice of methanation reactor, there are adiabatic reactors and isothermal reactors. I would like everyone to discuss the advantages and disadvantages of these two types of reactors, and which type is generally used in China? In my opinion, adiabatic beds can be used in systems with high gas flow rates, but they require a high temperature for the methanation catalyst. The catalyst has a short lifespan and high operating costs. Isothermal reactors are generally suitable for small and medium-sized installations; there is no need to use high-temperature resistant methanation catalysts. The construction of such reactors requires high standards, resulting in high initial investment costs, but the operating costs are low. Please feel free to speak up~
That makes sense. 1# *ongxwy
The Great Plains in the United States use adiabatic reactors
What catalyst? Can a fluidized bed be used?
This is a profound question; I have the same doubt, as I am not familiar with methanation either.
The shape of the catalyst is generally a Raschig ring
The three major players in methanation generally use adiabatic reactors; given the large scale of coal-to-natural gas production and the substantial volume of raw materials required for methanation, only large-scale operations can be economically viable
