CATALYTIC ROUTES TO LOW-AROMATICS DIESEL LOOK PROMISING

Arthur J. Suchanek Criterion Catalyst Co. L.P. Houston Producing low-aromatics diesel fuel may be accomplished catalytically rather than through large capital investment. Pilot-plant test results show that some catalyst types and catalyst systems such as various combinations of nickel-molybdenum (NiMo) and nickel-tungsten (NiW) on alumina in the presence of sulfur; noble metal on alumina for low-sulfur feeds; and noble metal on zeolite for moderate sulfur feeds can achieve the proposed tougher
