| Catalyst bed protection |
Wouter Bos, Dahlman Filter Technology
|
2006 / Catalysis |
Feedstock filtration upstream of the hydrotreating and hydrocracking processes can effectively protect the catalyst beds from fouling, and consequently increase cycle length and prevent premature shutdowns.

| Catalyst performance monitoring. |
Steve Philoon, UOP LLC
|
2006 / Catalysis |
A web-based catalyst performance-monitoring tool can improve profitability. The CPM system enables the process engineer to spend his time optimising the catalyst performance in the unit rather than manipulating data.

| Precious metals recovery |
Horst Meyer, Uli Blankenstein and J P Rosso, W C Hereaus GmbH
|
2006 / Catalysis |
The recovery of platinum and other precious metals from spent reforming
catalysts is essential. Of special significance are fast cycle times
and high return rates from precious metals refiners.

| Investigating hydrotreater performance |
Dave Ferguson and Mike Flenniken, Quest TruTec LP
|
2006 / Catalysis |
A discussion of the techniques for on-line investigations of feed/effluent exchangers and operating reactors. On-line investigation of diesel hydrotreating units can identify the causes of poor performance in catalyst beds.

| Avoiding FCC regenerator upsets |
David A Hunt and Adam Kasle, Grace Davison |
2006 / Catalysis |
A step-wise investigation into the causes of regenerator catalyst losses. Examination of all unit operating conditions indicates that lowering the regenerator bed level will eliminate catalyst upsets and increase unit charge rates.

| Troubleshooting ZSM-5 in the FCC |
Solly Ismail, Engelhard Corporation
|
2006 / Catalysis |
While using a ZSM-5 additive to increase propylene, one refiner experienced increases in FCC dry gas, coke and slurry oil, even at a reduced reactor temperature. Operational problems were identified and process strategies adjusted to increase LPG yields.

| Improving FCC catalyst performance |
Michael K Maholland, Intercat Inc
|
2006 / Catalysis |
Higher volumes of heavier feeds can be processed with additives designed to enhance base catalyst effectiveness. Deactivation and dehydrogenation problems are avoided, while catalyst selectivity and stability are preserved.

| Improvement in FCC pretreatment catalysts |
Vito F Bavaro, Fernando Maldonado, David McNamara and Kevin Carlson, Criterion Catalysts & Technologies
|
2006 / Catalysis |
A new NiMo catalyst designed for processing severe FCC feeds can surpass the performance achieved with previous-generation NiMo catalysts, increasing FCC unit conversion and improving the catalyst's lifecycle value.

| Maximising octane |
Lars K Skyum, Haldor Topsoe A/S |
2006 / Catalysis |
A large number of existing diesel hydrotreaters are operated at pressures below 30 bar. The catalyst used for production of ULSD in these hydrotreaters differs from catalyst formulations that perform well at higher pressures.

| Profitable resid processing |
Larry Hunt, Grace Davison
|
2006 / Catalysis |
As more refiners process a higher percentage of residual feedstock, FCC catalyst technology can help refiners processing resids overcome any negative effects on unit operation and operate more profitably and efficiently.

| Optimising multi-tubular reactors |
Cliff Johns, TubeMaster Inc
|
2006 / Catalysis |
Performance of multi-tubular catalyst reactors in the petrochemical industry can be improved with a combination of strategies. Among the strategies to be discussed is catalyst-loading technology.

| Fischer-Tropsch and GTL update |
Rene G Gonzalez
|
2006 / Catalysis |
Slurry phase Fischer-Tropsch reactor configurations appear to be generally favoured by most technology developers. Recent cobalt-based catalyst developments are accelerating gas-to-liquids commercialisation.

| Producing lubes and fuels |
Charlie Wills and Art Dahlberg, Chevron Lummus Global
|
2006 / Catalysis |
Hydrocracking is beneficial when producing both feed for lube base stocks and fuels. The integration of Isocracking/Isodewaxing catalysts with process for the production of premium lubricant base oils by hydroprocessing is discussed.
