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.

Achieving clean fuels objectives

Jeffrey Sexton, Kenneth M Barnes and Ron L Cordle, Marathon Petroleum Company LLC

Joe B McLean, C J Farley and James C Fu, Engelhard Corporation

2006 / Catalysis

Use of gasoline sulphur reduction catalyst technology in refinery applications is discussed.  One refinery shows how high bottoms conversion, gasoline and light olefin yield objectives can be achieved while maintaining a profitability focus.

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.

More

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.

More

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.

More

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.

More

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.

More

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.

More

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.
