Based on their experiments, the authors suggest a flowsheet for the chlorination of spent catalysts.

The company smelts and refines the spent catalysts by the same process as the mined production is purified.

Aldwich Malaysia operates a spent catalyst recycling plant and a refinery converting waste oil into diesel.

Fresh catalyst can be added, and spent catalyst withdrawn, to control the level of catalyst activity within the reactor.

"The primary source of domestic vanadium is through the recovery of spent catalysts from oil refinery operations.

Therefore, the facility would need to report the amount of the NPRI substance in the spent catalyst as a transfer off site for recovery.

The company recycles spent catalyst material to recover PGMs at the smelter and refinery.

The amount reported would be calculated by adding the amount of the NPRI substance in the spent catalyst for both transfers.

Specifically, the D-F releases would arise from the regeneration of spent catalyst from the reforming process at petroleum refineries.

The flow of spent catalyst to the regenerator is regulated by a slide valve in the spent catalyst line.

Demetallization: The commercial proprietary Demet Process removes nickel and vanadium from the withdrawn spent catalyst.

Platinum can be recovered from spent catalyst by conversion to ammonium chloroplatinate using aqua regia followed by ammonia.

The selective chlorination is based on difference in physicochemical properties of the chlorinated compounds of refractory metals, transition metals, and spent catalyst support.

A number of postgraduate students are being supervised on various projects ranging from bioleaching of metals to gas phase extraction of vanadium from spent catalysts.

The company has a longterm catalyst sourcing agreement and spot contracts with other suppliers who ship spent catalysts to the company for processing to recover PGMs.

What is the intent to list the "regeneration of spent catalyst at petroleum refineries" as a source activity of D-F reporting for NPRI?

Pyrometallurgy Spent catalysts and other residues are clearly identified They are thoroughly sampled and analysed, an out-turn is produced and the analysis reported before recycling commences.

DuraTherm addresses a variety of waste streams, including oil-contaminated drill cuttings, refinery wastes, petrochemical wastes, hydrocarbon- contaminated soils, spent catalysts, and other petroleum-compatible residuals.
