摘要： An aromatic oil say from catalytic cracking of hydrocarbon oil and/or a paraffinic oil as from solvent deasphalting of topped crude is air blown at elevated temperature and then further treated at elevated temperature in the presence of a catalyst, e.g., zinc chloride, to produce a hydrocarbon resin. The oil in which the resin has been produced is combined with a topped crude from which asphalt is to be produced or with an asphalt following which the admixture thus obtained is subjected to vacuum distillation or to a solvent deasphalting to remove unreacted or non-resinous, petroleum-derived fractions. An asphalt suitable for paving, having improved ductility and other properties, is obtained.

摘要： STRACTED FROM THE FIRST PORTION OF THE HYDROCARBON CRACKED IN THE FIRST PORTION OF THE ZONE.
THE TENDENCY OF HYDROCARBONS TO FORM HIGHER MOLECULAR WEIGHT DERIVATIVES THEREOF DURING CRACKING IS DIMINISHED BY CRACKING A HYDROCARBON LESS SUSCEPTIBLE TO THE FORMATION OF HIGHER MOLECULAR WEIGHT DERIVATIVES THEREOF IN A FIRST PORTION OF A CRACKING ZONE AND INTRODUCING TO THE CRACKING ZONE DOWNSTREAM OF THE FIRST PORTION THEREOF AN ADDITIONAL HYDROCARBON FRACTION MORE SUSCEPTIBLE TO THE FORMATION OF HIGHER MOLECULAR WEIGHT DERIVATIVES AND CRACKING THE LATTER IN THE PRESENCE OF HYDROGEN AB--

摘要： A method of making either a softener for rubber mixtures or a furnace fuel oil comprises the steps of heating a hydrocarbonaceous solvent and introducing thereinto waste from vulcanized or nonvulcanized rubbers under intensive stirring. Then the waste is thermally decomposed at a pressure of 5.multidot.10.sup.2 to 25.10.sup.5 n/m.sup.2, the hydrocarbonaceous solvent continuously circulating through the reaction mixture. The end product is separated from the formed suspension by distillation at a temperature of 200.degree. to 560.degree. C. and at a pressure of 10 to 2.multidot.10.sup.5 n/m.sup.2 in the presence of an inert gaseous agent.
