PROCESS FOR PREPARING A SEMI-SOLID FUEL COMPOSITION FROM NORMALLY-LIQUID HYDROCARBONS WHICH COMPRISES: (1) ADMIXING FROM ABOUT 1 TO ABOUT 20 PARTS BY WEIGHT OF A LIQUID HYDROCARBON BOILING WITHIN THE RANGE OF FRO, ABOUT 80*F. TO ABOUT 950*F. AT ATMOSPHERIC PRESSURE WITH 1 PART BY WEIGHT OF PROPYLENE POLYMERS ESSENTIALLY COMPRISING CRYSTALLINE POLYMERS HAVING MOLECULR WEIGHTS IN THE RANGE OF FROM ABOUT 30,000 TO ABOUT 1,000,000 AND WHICH ARE SUBSTANTIALLY INSOLUBLE IN THE LOWER NORMALLY-LIQUID ALKANES; (2) HEATING THE MIXTURE OF HYDROCARBON AND POLYPROPYLENE TO A TEMPERATURE ABOVE ABOUT 180*F. BUT BELOW ABOUT 270*F.; (3) VIGOROUSLY AGITATING SAID MIXTURE FOR A SHORT PERIOD OF TIME; (4) COOLING SAID MIXTURE WITH AGITATION TO A TEMPERATURE BETWEEN ABOUT 180*F. AND ABOUT 210*F.; (5) FURTHER COOLING SUCH MIXTURE, WITHOUT AGITATION, TO AMBIENT TEMPERATURE; AND (6) RECOVERING A SEMI-SOLID GEL COMPOSED OF LIQUID HYDROCARBON AND POLYPROPYLENE.
