실험 절차
The doped copper aluminum borate catalyst prepared in the preceding paragraph was ground to 18 to 40 mesh and used in the dehydrogenation of ethylbenzene and p-ethyltoluene in the manner described in Example I. The ethylbenzene runs were carried out at a 0.9 liquid hour space velocity, 620° C. temperature, steam:ethylbenzene molar ratio of 20:1, yielding 42% conversion and 72% selectivity to styrene. The p-ethyltoluene conversion to p-methylstyrene was carried out using a 0.2 liquid hour space velocity, 620° C. temperature, 15:1 molar ratio of steam to p-ethyltoluene, a 5:1 toluene to p-ethyltoluene dilution, yielding 68% conversion and 93% selectivity to p-methylstyrene.
