| Role of advances in FCC catalyst technology. |
J B McLean, D M Stockwell, W A Weber, W S Sinkler, M R Greczek, T E Masak, Engelhard Corporation |
2003 / Q1 |
Sulphur-reducing chemistry that preserves gasoline yield and
minimises octane loss while avoiding cut point penalties can help meet
clean fuel specifications where post treatment and additive systems may
not be adequate.

| The oxidative route to ULS production |
Robert E Levy, UniPure Corporation |
2003 / Q1 |
Refinery and terminal applications using modular designs where
extraction of oxidised sulphur and nitrogen species is carried out
without the processing severity and level of investment required with
conventional hydrotreating.

| Oxygen contamination of hydrocarbon feedstocks |
M Vadekar, Chem Tech Consulting |
2003 / Q1 |
An examination of the detrimental effects caused by dissolved O2 and
practical solutions to control fouling, corrosion and expensive
unplanned shutdowns when processing feedstocks vulnerable to air or
oxygen ingress.

| Catalyst formulations and FCC unit performance |
Ganesh Gandham and Alok Srivastava, Hindustan Petroleum Corporation Ltd |
2003 / Q1 |
The authors describe how careful selection of catalyst and additives
holds the key to achieving the objectives for improving naphtha RON and
throughput. Each refiner has to develop his own system for
choosing the appropriate catalyst.

| Crude Valuation for crude selection |
J C M Hartmann, Hartmann Refinery Consultancy |
2003 / Q1 |
A simulation model can give product yields/properties on separate crudes while an LP run indicates the cost of using limited facilities and markets. Together they show the relative values of crudes for a specific refinery in a specific market.
