From an experimental equation, IF=Tθa, product yields were estimated, where IF is the intensity function (°C•seca), T is the reaction temperature (°C), θ is the residence time (sec), and a is a constant (-). The effect of the structure of polyolefin on the value of \"a\" was also discussed.The pyrolysts conditions used in this study were as follows: temperature, 500∼800°C; the residence time, 0.6∼7.1sec; and the dilution ratio of steam to polymer by weight, 0.6∼7.5.The operating factors were inferred to be reaction temperature and residence time. For a given product yield, these two factors were interchangeable. Equations for yielding methane were expressed as_follows: (PE): IF=Tθ0.04, (PP); IF=Tθ0.05, (PIB); IF=Tθ0.07.As IF was correlated to the product yield, the product yield could be predicted by some appropriate choice of pyrolysis conditions. The value of \"a\" of a polyolefin was correlated to the activation energy (ΔE) for thermal degradation and to temperature (T1/2) corresponding to 50% weight loss. These two parameters were determined from the TG curve.","PeriodicalId":9596,"journal":{"name":"Bulletin of The Japan Petroleum Institute","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"1977-11-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89822806","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}
