Modeling of Catalytic Fixed

A comprehensive review of the various studies reported in the literature to date on the mathematical modeling of fixed-bed reactors for the production of fuels by the Fischer–Tropsch synthesis (FTS) was carried out It is quite clear that most of the proposed models are based on a set of assumptions that allow their wide simplification by reducing the models into forms of low complexity due Get price

Fischer–Tropsch process

A fixed-bed reactor is suitable for operation at low temperatures and has an upper temperature limit of 257 C (530 K) Excess temperature leads to carbon deposition and hence blockage of the reactor Since large amounts of the products formed are in liquid state this type of reactor can also be referred to as a trickle flow reactor system Get price
