Gasoline with reduced content of benzene - Technological changes.

Benzene content in gasoline can be reduced by splitting the reformate into light and heavy reformate and than blending the low-boiling fraction with t he high aromatic reformer which is produced to obtain aromatic hydrocarbons in industrial scale. On the basis of the study it was find out that 30% vo l. of low boiling fraction (T less than or equal to 100 degrees C) does not affect the aromatic extraction process. The extraction process was run by a single-stage method at temp. 60 degrees C, feed: solvent ratio 1:4; the s olvent bring NMP and MEG at a weight ratio of 60 to 40. Parameters are simi lar to those of the Aromatic Extraction Process in Polish Petrol Concern S. A. Plock. For comparison the experiments with the high aromatic reformer we re carried out.
