| Assessing catalyst quality |
Pierre Dufresne Fréderic Jardin François Locatelli, Eurecat SA
|
2004 / Catalysis |
Increases
in ultra-low sulphur fuel production will require new catalytic tests
to assess the reusability of regenerated HDS catalysts. New surface
area and activity correlations needed for these tests are discussed

| Recycling of GTL catalysts |
Andreas H Brumby and Michel P Verhelst, Umicore Precious Metals Refining
|
2005 / Catalysis |
Recovery
and refining of cobalt and precious metals used in Fischer Tropsch
catalysts should be considered due to their value. The impact of
certain precious metals on the metals markets also justifies their
recovery

| Reformer catalyst Regeneration |
Dick Llorens, Gemini Industries Inc
|
2005 / Catalysis |
To
make a proper evaluation of the economics of spent catalyst
regeneration, one must consider the direct and indirect costs, risks
and long-term liabilities that occur when the catalytic reforming
unit’s catalyst regeneration process is abbreviated

Peter J H Carnell and Steve Willis, Johnson Matthey Catalysts
|
2005 / Catalysis |
Various
methodologies for the measurement of mercury levels in gaseous and
liquid hydrocarbons are available, while inorganic routes for mercury
removal have a number of advantages over the organic approach

| Styrene catalyst performance monitoring |
Dennis Yieh, Sterling Chemicals Holding Inc
R Newman, CRI Catalyst Co
|
2003 / Catalysis |
Real-time
performance-monitoring software is readily adaptable to a variety of
catalysts due to the speed at which the system permits plant operators
to respond to changes in the process of market, allowing more
profitable production decisions.

| Recovering and refining precious metals from spent catalysts |
Kevin M Beirne, Sabin Metal Corp, East Hampton, NY, USA
|
2003 / Catalysis |
In
addition to obtaining the most effective expertise in precious metal
recovery, serious consideration must be given to financial and legal
issues that could arise when partnering with a precious metal refiner.
