HDS and HDN of a heavy FCC gasoline (HCN) and a mixture of pyrolysis gasoline/HCN were studied over a modified bimetallic alumina catalyst in a pilot scale reactor. The tests were aimed to determine favorable process conditions resulting in high octane number and low (< 10 mg/kg) sulfur content of the product. The process conditions were 230-280°C; 0.5 MPa; H2/hydrocarbon: 150 cu m/cu m; and liquid hourly space velocity 2.0-5.0/hr. Under preferred operating conditions, sulfur content of the feed was reduced to 5-10 mg/kg, olefin saturation was 20-55%, loss of RON was 1-2 units, but nitrogen content was not significantly reduced. This is an abstract of a paper presented at the 230th ACS National Meeting (Washington, DC 8/28/2005-9/1/2005).
