実験手順

The same Ca-P-ZSM-5 catalyst is then treated with a stream of air which is first moistened with water at ambient temperature and is then passed for 14 hours at the rate of 300 cc/minute into the catalyst bed maintained at 90° C. After calcination at 500° C. for 1 hour, disproportionation and ethylation of toluene are again carried out under the same conditions used with the untreated catalyst. Toluene disproportionation gives 12.6% toluene conversion with a para-selectivity of 66.3% p-xylene in xylenes. Toluene ethylation gives 19.1% conversion of toluene with a para-selectivity of 88.7% p-ethyltoluene in ethyltoluenes.
