Fast-tracking catalyst development

 Derek Atkinson, Oxford Catalysts

2008 / Catalysis

High throughput experimentation is helping to reduce the time required to commercialise new catalysts.  The need to test the impact of a range of variables on catalyst performance makes it vital to consider all pathways that can minimise development time.

Increasing catalytic reforming yields

Mark P Lapinski, Joe Zmich and Steve Metro, UOP Nungruetai Chaiyasit and Kosol Worasinsiri, PPTAR

2008 / Catalysis

Case study where a CCR Platforming process unit increased profitability by changing to a high-density catalyst.  Higher aromatic yields and the ability to load new catalyst without a unit shutdown helped to justify the costs.

Increasing refinery biofuels production

Kerry L Rock and Maurice Korpelshoek, CDTech

2008 / Catalysis

The benefits of producing bio-ethers with catalytic distillation compared to blending bio-ethanol are addressed.  Options such as the conversion of MTBE units to ETBE production, combined with skeletal isomerisation, can provide higher volumes of high-octane gasoline.

Combining ULSD objectives with FCC pretreatment

Lars Skyum, Haldor Topsoe A/S

2008 / Catalysis

Catalysts for ULSD and FCC pretreatment combine higher activity, better stability and lower hydrogenation consumption.  This combination of catalyst functionalities becomes important when considering either direct desulphurisation or hydrogenation.

Cracked feed protection for HDS catalysts

Randy Alexander and Nilanjan Brahma, Eurecat US

Pierre Dufresne, Eurecat SA

2008 / Catalysis

It is now possible to process cracked feeds through a hydrotreater immediately after start-up without the risk of premature coke and gum formation, and excess temperature limits and hydrogen consumption.

Maximising ULSD with cracked feedstocks

Charles Olsen and Brian Watkins, Grace Davison

Woodrow K Shiflett, Advanced Refining Technologies

2008 / Catalysis

Balancing hydrogen consumption can give flexibility when processing cracked feedstocks.  Case studies show the performance of a catalyst system combining CoMo- and NiMo-based formulations based on available hydrogen pressures and amount of LCO/LCGO feedstocks.

Tar sands oil upgrading technology

 Donald B Ackelson, UOP LLC

2008 / Catalysis

Technology for processing heavy crudes and bitumen-derived materials such as synthetic crude oil are examined, along with the challenges they present to primary and secondary refinery conversion units.

More

Reducing FCC unit NOx emissions

Charles Radcliffe, Intercat Inc

2008 / Catalysis

Mechanisms of FCC unit Nox formation and logical steps to minimise these emissions are discussed.  Performance examples at each state of operation using additives are provided.

More steam cracker integration options

Vasant Bhirud, Ethylene Consultants

2008 / Catalysis

Recently developed catalytic-based technologies can improve steam cracker operations and economics.  The integration of steam cracker operations with refinery and propane dehydrogenation operations is considered.
