| 发明名称 | Method for manufacturing olefins | ||
| 摘要 | The present invention relates to a process for producing an olefin, including the step of subjecting an aliphatic primary alcohol having 12 to 24 carbon atoms to liquid phase dehydration reaction in the presence of a solid acid catalyst, wherein among a total acid content of the solid acid catalyst as measured by an ammonia temperature-programmed desorption (NH3-TPD) method, an acid content of the solid acid catalyst as calculated from an amount of ammonia desorbed at a temperature not higher than 300° C. in the method is 70% or larger of the total acid content. | ||

| 主权项 | 1. A process for producing an olefin, comprising subjecting an aliphatic primary alcohol having 12 to 24 carbon atoms to liquid phase dehydration reaction in the presence of a solid acid catalyst, wherein among a total acid content of the solid acid catalyst as measured by an ammonia temperature-programmed desorption (NH3-TPD) method, an acid content of the solid acid catalyst as calculated from an amount of ammonia desorbed at a temperature not higher than 300° C. in the method is 70% or larger of the total acid content, wherein said liquid phase dehydration reaction is carried out at a temperature of from 160 to 290° C. and wherein the solid acid catalyst is alumina or aluminum phosphate. | ||
