Abstract
The deactivation of catalysts by coke-forming structures in the dehydrogenation of higher n-paraffins is discussed. The patterns of coke formation on a catalyst subject to process conditions are presented. A mathematical model of the process is described to show its adequacy. A calculation algorithm for the optimum mode of operation of a dehydrogenation catalyst is constructed, and the calculation results are given. Dehydrogenation catalysts of different brands are compared with respect to several parameters (coke formation on catalysts, the yield of the reaction by-product, and the dynamics of temperature rise in the reactor). The model can be used to estimate the efficiencies of catalysts in a cycle and to compare them.
