Title

MODELING OF CATALYTIC COKE RATE IN THE PRESENCE OF H2S IN THE THERMAL CRACKING OF ETHANE

Pages

  75-84

Abstract

 Generally, during the THERMAL CRACKING of hydrocarbons, carbon (coke) are formed either on the wall of the reactor or in the gas phase. Coke formation is an unwelcome and undesirable product. Hence, the sulfur compounds usually are used as an additive in order to prevent coke formation and CO production. The most important mechanism in the coke formation in the THERMAL CRACKING of hydrocarbons, is the catalytic mechanism. In this work, catalytic coking mechanism in the presence of H2S in the THERMAL CRACKING of ethane has been investigated. The coke rate equations has been proposed by suggested mechanisms. The RATE COEFFICIENTs for these models were determined using non-linear Marquardt-Levenberg optimization. THE SUM OF SQUARES OF THE DEVIATIONS between the calculated and experimental data was used as the objective function and minimized. Finally, the experimental and calculated data were compared and one of the mechanisms agrees with the experimental data in a better accuracy.
