Abstract

The invention relates to the technical field of processing fuel oil, in particular to 98# vehicular gasoline and a preparation method thereof. The invention discloses the high-grade 98# vehicular gasoline prepared by adopting catalytic gasoline and additives such as ethyl tert-butyl ether (ETBE), dimethylbenzene, aromatic hydrocarbon, an octane number improver and the like, and the preparation method thereof. The octane number of the clear gasoline prepared by the method reaches the standard requirement of the 98# vehicular unleaded gasoline, and part of indexes is superior to the national standard requirement; and the product is safe and environmental-friendly, fully utilizes the catalytic gasoline, improves the industrial added value of the catalytic gasoline product, and has simple process and convenient and feasible operation.

Description

technical field [0001] The invention relates to the technical field of fuel oil processing, in particular to No. 98 motor gasoline and a preparation method thereof. Background technique [0002] The quality of fuel oil products is closely related to automobile emission regulations. The reason why the United States, Europe and Japan have invested a lot of manpower and material resources in the correlation between oil product quality and emissions is to proceed from the actual situation of the country and fully consider the country's crude oil resources, road conditions, and oil refining. Factors such as plant structure and vehicle engine condition, these inputs have played a protective role in the country's petrochemical enterprises and automobile industry. However, my country's oil refining process is formed according to historical factors such as the demand for oil products in the Chinese market and the characteristics of crude oil, and there are certain differences with fo...
