FCC Catalyst for cleaner gasoline

Daniel McQueen, Paul A Diddams, Grace Davison, Worms, Germany

2003 / Catalysis

Removal of thiophenic and olefinic compounds while maintaining high octanes is an important challenge facing refiners producing clean gasoline.
More

Ultra-deep desulphurisation of gas oils

Lars Skyum, Haldor Topsoe A/S, Copenhagen, Denmark.

2003 / Catalysis

In order to choose the right combination of catalyst and technology for the production of diesel with 10ppm sulphur or less, it is essential to have a thorough understanding of the reaction kinetics in diesel hydrotreating from SOR to EOR.
More

Butane and light naphtha isomerisation

Scott Graeme, Michel van der Laan, Akzo Nobel Catalysts, The Netherlands

2003 / Catalysis

Low-density, platinum-based cylindrically shaped catalysts can overcome maldistribution problems and improve catalyst performance measured by PIN, H2/HC and isobutane ratios, and characterised by higher activity, short loading and lower costs.
More

New catalyst formulations for semi-regenerative reformers

Gary A Marr, UOP, Des Plaines, Illinois, USA

2003 / Catalysis

Two European refineries upgrade reformer technology, resulting in higher reformate and hydrogen yield with improved RONC and longer intervals between regeneration.
More

Grading and topping materials for hydrotreating applications.

David Berman, Tricat Inc, Hunt Valley, Maryland, USA

2003 / Catalysis

Extrudates are being remanufactured into alternative sizes and shapes for reactor activity grading and void-space grading as well as to help prevent pressure drop build-up caused by particulates and polymerisation.
More

New catalysts for reformers.

Pierre-Yves Le Goff, Fabienne Le Peltier, Bruno Domergue, Axens
Jean-Francois Joly, IFP France

2003 / Catalysis

More

Optimised high-quality BTX production

Thi Chang, Technical Editor, Houston, TX, USA

2003 / Catalysis

Transalkylation catalysts are able to convert heavy aromatics into high-quality petrochemicals at lower recycle rates and with increased run lengths without the need for a solvent-extraction unit.
More

Technology for propylene boosting in steamcrackers.

Heinz V Boelt, Stephan Glanz, Linde

2003 / Catalysis

Integration of steamcracker C4/C5 components with a fixed-bed fluid catalytic-cracking reactor employing a shape-selective heterogeneous zeolytic ZSM-5 catalyst.
