1. The results of laboratory studies on the catalytic hydrocracking of naphtha distillates were confirmed by tests on a commercial unit. 2. The resulting iso-component consisted mainly of C5 and C6 isoparaffins, and had a motor-method octane number of 84–86. 3. The C7+ cut, used as a feedstock for catalytic reforming, proved to be somewhat better in quality than hydrotreated straight-run naphtha. 4. Feasibility has been confirmed for producing AI-93 gasoline by blending the iso-component with severe-regime reformer naphtha, without the use of ethyl fluid, alkylate, or isomerizate, as well as producing AI-93 gasoline by blending the iso-component with mild-regime reformer naphtha and adding 0.82 g TEL/kg. 5. Stable operation of the catalyst has been demonstrated in an extended commercial run.
