ExxonMobil Research and Engineering Company has announced that its proprietary lube catalyst technology will be used by specialty refiner Calumet Shreveport Lubricants and Waxes at its Shreveport, Louisiana facility.

Calumet is converting and expanding its existing fuels and lubes dewaxing process into a higher capacity operation, enabling it to produce 8,600 barrels per day of high quality base stocks.

ExxonMobil said that the expanded lube train will use its proprietary lube catalyst technology, including MSDW catalytic dewaxing and MAXSAT hydrofinishing catalysts, and the corresponding reactor design.

The expansion is proceeding on an accelerated 18-month schedule with startup expected in the first quarter of 2008.
