Removal of carbon disulfide via coupled reactions on a bi-functional catalyst: experimental and modeling results.
A mathematical model describing the rate of carbon disulfide (CS(2)) removal due to coupled reactions has been developed. Kinetic studies were carried out in a fixed bed reactor under atmospheric pressure and a range of temperatures (85-125 degrees C). The effects of flow rate, CS(2) inlet concentration, temperature and relative humidity were analyzed. A kinetic model based on axial dispersion, external and internal mass-transfer resistances, as well as effects of S deposition on the inner-face of the catalyst was in agreement with the CS(2) experimental breakthrough curves. The mathematical model can be used for process design and scale up of similar systems.
