Abstract: A RESIDUE-CONTAINING PETROLEUM FRACTION, 50 PERCENT BOILING ABOVE 1,000*F., IS HYDROCRACKED AND THEN HYDRODESULFURIZED. DURING THE ONSTREAM PERIOD, THE CONVERSION LEVEL OF MATERIAL BOILING ABOVE 1,000*F. IS MAINTAINED SUBSTANTIALLY CONSTANT WHILE THE SULFUR CONTENT OF THE HYDROCRACKED EFFLUENT INCREASES. THE SULFUR CONTENT OF A PRODUCT FRACTTION IS MAINTAINED SUBSTANTIALLY CONSTANT BY GRADUALLY INCREASING THE HYDROSULFURIZATION TEMPERATURE. THE EFFLUENT FROM THE HYDROCRACKING REACTTION IS COOLED BY ADDING AN AROMATIC-RICH FRACTION AND THE COOLED MIXTURE IS PASSED TO THE DESULFURIZATION REACTION.

Abstract: A residue-containing petroleum fraction, 50 percent boiling above 1,000* F, is hydrocracked and then hydrodesulfurized. During the onstream period, the conversion level of material boiling above 1,000* F is maintained substantially constant while the sulfur content of the hydrocracked effluent increases. The sulphur content of a product fraction is maintained substantially constant by gradually increasing the hydrodesulfurization temperature. The effluent from the hydrocracking reaction is cooled by adding an aromatic-rich fraction and the cooled mixture is passed to the desulfurization reaction.
Abstract translation: 将含有50％沸点高于1000°F的含残渣的石油馏分进行加氢裂化，然后加氢脱硫。 在上游期间，沸点高于1000°F的材料的转化率保持基本恒定，而加氢裂化流出液的硫含量增加。 通过逐渐增加加氢脱硫温度，产物馏分的硫含量保持基本恒定。 通过加入富含芳烃的馏分来冷却来自加氢裂化反应的流出物，将冷却的混合物通入脱硫反应。
