DESULPHURISATION OF A GASOLINE FRACTION FROM PARTIALLY CRACKED NAPHTHA

A substantial desulphurisation of an 80-180°C gasoline fraction obtained from a partially, thermally cracked naphtha was possible by the use of a high iron clay. The operation was carried out by the contact of the gasoline vapours with a fixed-bed of the clay in a laboratory assembled quartz tube reactor. It was possible to reduce the sulphur content of the gasoline fraction from 0.3 wt% to 0.03 wt% at a temperature of 600% and a space velocity of 1.0 h−1. Analysis of the clay samples are given and the results on its role in desulphurisation may point to some important practical potentials.
