THE STRUCTURAL DETERMINATION OF FLOWS IN THE SINGLESTAGE REACTOR FOR THE SULPHURIC ACID ALKYLATION
Аннотация и ключевые слова
Аннотация (русский):
The article considers the flow sulphuric acid alkylation reactor designed to produce the high-octane component of petrol fractions and aviation fuel. The industrial application uses the narrow fractions containing the necessary hydrocarbons as raw materials. Isobutane has the greatest practical importance for alkylation but it is used as a raw material in relatively small quantities. The quality of the resulting alkylate decreases depending on the olefin used. The industrial plants implement new engineering measures to improve the technical and economic efficiency of the operations. Consequently, the main trends in the modern sulphuric acid alkylation process are: the construction of new high-capacity units based on advanced technologies; increase of raw material resources for alkylbenzene production; search for thecatalysts and new methods for alkylation of isobutane with olefins; development of highly efficient technologies.
