Cracking of tetralin and t-decalin has been investigated in the temperature range between 700 and 850 °C and with residence times between 0.08 and 0.4 s. Most of the tetralin is dehydrogenated to yield 1,2-dihydronaphthalene and naphthalene. Other main products are indene and styrene, whereas t-decalin is predominantly cracked into ethylene and BTX aromatics. The kinetics of decalin decomposition can be described by a first-order irreversible reaction, whereas the behaviour of tetralin has to be expressed in terms of a reversible reaction. The overall activation energies are determined. |
