Abstract

The invention discloses a method for determining octane number in gasoline. The method comprises the following steps: S1, sampling a gasoline sample; S2, testing a maximum detonation value of the gasoline sample; S3, inputting the data into a data memory; S4, obtaining the octane number of the gasoline sample through comparison and calculation of the data processor; S5, distilling the gasoline sample; S6, cutting the gasoline taken out from the tower top of the distillation tower into two parts at 95 DEG C, namely, a gasoline light component before 95 DEG C and a gasoline heavy component after95 DEG C; S7, respectively testing the octane numbers of the gasoline light component and the gasoline heavy component, and determining whether the octane number distribution of the gasoline is uniform or not according to the octane number difference of the two components; and S8, obtaining the octane number and the quality of the gasoline sample according to the results of the step S4 and the step S7. According to the method for determining the octane number in the gasoline, the operation method is simple, the octane number of the gasoline is simply, conveniently, efficiently, accurately andfully automatically determined, and the quality of the gasoline is rapidly judged.

Description

Technical field [0001] The invention belongs to the field of gasoline assessment, and in particular, the method of determining the octane values ​​in gasoline. Background technique [0002] Gasoline production is an important part of the petroleum refining industry. The state has strict index requirements for the quality of gasoline, of which octane is the first quality indicator of gasoline specifications. The determination of gasoline octane is determined by gasoline octane measuring machine, and then calculates the maximum knock index of two standard oil samples, and obtains the maximum knock index. It is produced in a state in which a suitable air is mixed with the oil and gas ratio of the oil, and therefore, it is determined that the maximum knock intensity mixed oil and gas ratio is the key to gasoline octane measurement. [0003] In fact, gasoline is a mixture of C4 to C12. The octane values ​​specified in the national standard are the average octane values ​​of the mixtur...
