The yield of 2, 5-NBD was enhanced with rise in the reaction temperature and showed a maximum yield at 420°C. On the other hand, the formation of toluene initiating at 400°C increased with increasing temperature and with a simultaneous decrease in the yield of (2, 5-NBD). At 550°C, the yield of toluene was 30% and the selectivity was 75%. The formation of toluene was also observed in the reaction of 2, 5-NBD. Therefore, it was concluded that 2, 5-NBD was an intermediate of toluene. This was consistent with the kinetic studies on the formation of toluene. The menchanism of the addition of acetylene to CPD was also discussed and as a result, the role of a radical mechanism, in addition to that of a concerted one, was also assumed.","PeriodicalId":9596,"journal":{"name":"Bulletin of The Japan Petroleum Institute","volume":"62 2","pages":"153-157"},"PeriodicalIF":0.0,"publicationDate":"1976-11-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"72613552","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The flow rate of the emulsion was varied from 100 to 600ml/min. The effects of the amount of ferrofluid added, the magnetic field and the flow rate of emulsion on the oil removal efficiency were studied. As a result, the oil removal efficiency increased as the amount of ferrofluid added and the strength of magnetic field increased, but it decreased as the flow rate of emulsion increased. Ferrofluid is a stable colloidal dispersion of magnetic particles (D<150A) whose carrier liquid is kerosene.An equation for oil removal efficiency was theoretically derived. The calculated and measured values of oil removal efficiency are shown.","PeriodicalId":9596,"journal":{"name":"Bulletin of The Japan Petroleum Institute","volume":"37 1","pages":"183-189"},"PeriodicalIF":0.0,"publicationDate":"1976-11-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86901877","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Among the catalysts tested, the graphite-supported Rh catalyst showed the highest rate of production of C2 hydrocarbons. In the whole range of conversions, the graphite-supported Rh catalyst produced C2 hydrocarbons more selectively than the alumina-supported or charcoal-supported catalysts. This difference was considered due to the strong metal-support interaction in the graphite-supported catalyst that involved electron transfer between rhodium and graphite.
