| Description |
Residue up-gradation is at the zenith of value addition. Among the various processes used, delayed coking
provides the complete conversion of the feedstock to gas, distillates, and coke. In the present work, the
kinetics of coking of Arab mix short residue (AMSR) was investigated in the temperature range of 430-475 °C
and the reaction times and total pressure upto 90 min and 0.2 MPa, respectively. The reaction mixture was
analyzed for gas, distillates, coke and unconverted VR. While the distillate and gas yields showed linear rise at
low severity, the coke formation takes place only after certain induction period. A five lump kinetic model
comprising of vacuum residue (VR), gas (G), distillates (D), Intermediate (I) and the coke (C) has been
developed. All the steps in thermal cracking were found to follow first order kinetics. The activation energy for
cracking of VR and formation of I were found to be 55 and 66 kcal/mol, respectively, while for
polycondensation reactio~ of I to C, the activation energy was found to be 65 kcal/mol.
