Sažetak
Influence of mass transfer resistance on the rate of Ni/Al2O3 deactivation by thiophene in the reaction of benzene hydrogenation was investigated. The process was studied using the gas-flow differential fixed bed reactor at atmospheric total pressure on catalyst pellet 5*5 mm in the temperature range from 373 to 473 K. Excellent agreement was found with a power law equation da/dt=kd * ad. The results indicate that the deactivation rate constant decreases with increasing temperature with simultaneous increase in deactivation order.
