Abstract

The invention discloses a reactor for synthesis of alkylate oil. The reactor comprises a reactor cylinder 1, which consists of a straight tube section 2, a wide diameter section 21 and a transition section 5 between the straight tube section and the wide diameter section. An inner tube lower tube plate 14 and an outer tube lower tube plate 12 are disposed at the lower part of the straight tube section, and an upper tube plate 4 is arranged at the joint of the straight tube section and the transition section. The upper end and lower end of an outer tube 9 are respectively connected to an upper tube plate and the outer tube lower tube plate, the middle-upper part of an inner tube 10 is disposed in the outer tube, the upper end of the inner tube is a blind end, the lower end of the inner tube is connected to the inner tube lower tube plate, and the inner tube is provided with holes. Compared with existing industrial reactors, the reactor provided by the invention has good acid hydrocarbon contact effect, accelerates the reaction rate, reduces the reactor size, at the same time lowers alkyl-olefin ratio, and can strictly control the reaction temperature and reduce reaction by-product, thereby increasing the yield and quality of alkylate synthetic oil, and reducing the energy consumption needed by isobutene circulation.

Description

technical field [0001] The invention relates to a reactor used for synthesis of alkylate oil, which belongs to the field of chemical industry. Background technique [0002] The industrial isooctane produced by the alkylation reaction of C4 olefins and isobutane is a blending component of high-octane gasoline with various trimethylpentane as the main component. Industrial isooctane has a high octane number and combustion The advantages of less harmful products and lower vapor pressure. Alkylation reaction can be divided into sulfuric acid alkylation process and hydrofluoric acid alkylation process according to the catalyst used. Hydrofluoric acid is a volatile and highly toxic chemical. Once leaked, it will cause serious harm to the environment and production. The main disadvantage of the sulfuric acid alkylation process is the large discharge of waste acid. The sulfuric acid alkylation process is mostly used in my country. It is generally believed that the control step tha...
