摘要: A newroute towards phenol production by one-step selective hydroxylation of benzenewith hydrogen peroxide over ultrafine titaniumsilicalites-1 (TS-1) in a submerged ceramic membrane reactorwas developed, which can maintain the in situ removal of ultrafine catalyst particles fromthe reaction slurry and keep the process continuous. The effects of key operating parameters on the benzene conversion and phenol selectivity, as well as themembrane filtration resistance were examined by single factor experiments. A continuous reaction process was carried out under the obtained optimumoperation conditions. Results showed that the systemcan be continuously and stably operated over 20 h, and the benzene conversion and phenol selectivity kept at about 4% and 91%, respectively. The ceramic membrane exhibits excellent thermal and chemical stability in the continuous reaction process.
