| description | Catalytic reforming is the most used method for upgrading straight-run gasolines. The trends to modernize catalytic systems so that the reforming process can be used in the industrial setting are focused on the production of catalysts with a specifi c set of characteristics allowing to obtain a liquid commercial product with the required operational and ecological features, in addition to increase its yield at lower temperatures. This article investigates the effi ciency of the catalytic systems Pt/CVM, Pr/CVM as transformation processes of raw hydrocarbons. A high molecular weight ZSM zeolite (ZSM-5) has been used as a carrier. The raw material that has been used is a stable hydrogenate obtained through hydrotreatment, which is the main raw material of the reforming process. The octane number of the hydrogenate is 63, which is not acceptable for automobile gasolines. The transformation of the crude material results in the production of liquid fuel made up of multiple components and carbon atoms in a chain ranging from 3 to 14 atoms, as well as gases containing hydrocarbons С1 – С5 . In this work, the transformation of a stable hydrogenate on the catalysts under investigation has showed that temperature increase results in a higher octane number and aromatic content. It has been determined that temperature increase results in the reduction of the eff ects of the isomerization reaction, with a subsequent decrease in isoparaffi nic content. With a transformation of a stable hydrogenate on the catalyst Pt/СVM at temperature of 400°С, the benzene content amounts to 0,8 wt. %, which corresponds to the EURO-5 automobile gasoline standard. |
