Kinetics of the primary cracking reactions occurring in the high pressure thermal hydrogenolysis of 1, 2, 3, 4-tetrahydronaphthalene (tetralin) and hydrindene (indan) were studied in a flow reactor at temperatures from 460° to 540°C, total pressures from 10 to 160 atm. and molar ratios of hydrogen-to-hydrocarbon from 2 to 100. As primary cracking products from tetralin were identified n-butylbenzene, styrene, ethylene, 1-methylindan and o-propyltoluene. From indan were obtained n-propylbenzene, toluene, ethylene, o-ethyl-toluene, o-xylene and methane. Chain mechanisms are proposed for the reactions leading to these primary products. The theoretical rate equations derived from these are in good agreement with experimental results. |
