The oil refining and petrochemical industries use a large variety of catalysts to produce valuable products. Due to some reasons catalysts deactivate over time. In many cases the major reason of deactivation is the accumulation of a coke layer on the catalyst surface, thus covering the active sites or strong adsorption of certain fines on active sites.

Such type of deactivation is reversible and thus regeneration of the catalyst is possible. Removal of coke layer or decomposition of the adsorbed fines can recover the activity. This removal of the coke layer can be accomplished via controlled ex-situ regeneration, thus providing benefits such as reduced processing time, safer handling and increased recovered catalyst activity and its operating life. All catalyst regeneration plants are also capable to remove volatile hydrocarbons or water from inert gas for better temperature control during regeneration in oxygen. This eliminates unwanted side effects on catalyst layers and metals due to use of high temperatures or water.

Our company offers the services of ex-situ regeneration. At each stage of work we take the catalyst samples. The samples are taken prior to the regeneration – to determine optimum regeneration conditions; during the ·· regeneration – to ensure the quality control; after the plant regeneration – to provide a certificate of analysis for the final product.

After receipt of a pre-job report the Customer will be asked to give the “GO” / “NO GO” – whether to start the plant regeneration of catalyst batches which are suitable for regeneration or not. If necessary, lab regenerated catalyst samples can be made available for additional testing by the Customer or the original catalyst manufacturer prior to the industrial regeneration. The plant regeneration will only be performed after completion of a pre-job report and receipt of regeneration approval from the Customer.

The regenerated catalyst will meet the catalyst regeneration guarantees. Additional guarantees for the Customer may be agreed in writing prior to the start of plant regeneration.

The waste products (spent dust and fines, oversized support materials) remain the property of the Customer and will either be returned to the Customer together with regenerated catalyst or they will be forwarded to a reclaim company on behalf of the Customer. Waste products will be packed in clearly identified drums.

All the formalities related to packaging, transportation and customs clearance of the catalyst the company OptimLine Technologies shall settle on its own.

The significance of the quality of catalysts for oil refinery can’t be emphasized too strongly. Having a price incomparably smaller than total cost of final refinery product, low quality catalyst may lead to long term production shutdown and consequently to multimillion losses.
