Abstract

The invention provides a method for predicting the octane number of gasoline. The method comprises the following steps of firstly, collecting the sample data in a catalytic cracking gasoline refining desulfurization device, including the raw material octane number RON, the saturated hydrocarbon (alkane+cycloalkane) content, the aromatic hydrocarbon content, a bromine value, the coke content (the spent adsorption property), the coke content (the regeneration adsorption property), a hydrogen-oil ratio and the like, and then bringing the sample data to an octane number prediction model for calculation, so that the octane number prediction value can be obtained. The method for predicting the octane number of gasoline provided by the invention is simple to operate and is high in accuracy, and can replace a traditional experimental determination method to a certain extent.

Description

technical field [0001] The invention belongs to the field of petrochemical industry and relates to a method for predicting the octane number of gasoline. Background technique [0002] Most of my country's imported crude oil is sulfur-containing and high-sulfur crude oil from the Middle East. Heavy oil in crude oil usually accounts for a large proportion, and this part of heavy oil (which also contains high impurities represented by sulfur) is difficult to be directly utilized. In order to effectively utilize heavy oil resources, my country has vigorously developed heavy oil lightening technology with catalytic cracking as the core. More than 70% of gasoline is produced by catalytic cracking, so more than 95% of sulfur and olefins in finished gasoline come from catalytic cracking gasoline. Therefore, the catalytic cracking gasoline must be refined to meet the gasoline quality requirements. [0003] The octane number (expressed in RON) is the most important indicator reflect...
