    Abstract: A CONTINUOUS PROCESS FOR SULFURIZING POLYBUTENES FOR USE IN METAL WORKING LUBRICANTS, AND A REACTOR FOR USE IN CARRYING OUT THE CONTINUOUS PROCESS, INCLUDING INTRODUCING MOLTEN SULFUR AND POLYBUTENES INTO AND ENCLOSED CHAMBER WHERE FLOW THERETHROUGH IS INTERCEPTED TO PROVIDE A SERIES OF REACTION ZONES, MIXING TO PROVIDE INTIMATE CONTACT IN AT LEAST EACH ZONE SITUATED IN THE INITIAL ONE THIRD OF THE CHAMBER VOLUME, RECYCLING SULFUR COLLECTING ON THE BOTTOM OF AT LEAST THE ZONES IN THE INITIAL ONE THIRD OF THE VOLUME, ALLOWING FLOW FROM ONE ZONE TO ANOTHER, MAINTAINING THE CHAMBER AT FROM 300*F. TO 400*F. AND COORDINATING THE VARIOUS FLOW RATES AND THE CHAMBER VOLUME WITH THE REACTION TEMPERATURE TO PROVIDE A PREDETERMINED CHAMBER RESIDENCE TIME.

    Abstract: A catalytic composition consisting essentially of an amorphous silica-alumina support having dispersed therein ultrastable, large-pore, substantially metal cation free, crystalline aluminosilicate material, a metal of Group VIA, and at least one metal of Group VIII of the Periodic Table of elements. A method of preparing this catalytic composition which comprises adding ions of the metals to a silica-alumina sol, adjusting the pH of the composition, precipitating the sulfides of the metals, adding finely divided aluminosilicate material, drying, and calcining the resultant mixture. A hydrocarbon-conversion process employing this catalytic composition, particularly a process for hydrocracking nitrogen-contaminated hydrocarbon fluids.
