Services
CPERI contributes to the increased competitiveness of the Greek and European industry by providing unique and innovative solutions to research problems of technological and/or commercial interest.
CPERI’s R&D results have led to the development of new products and services that have found applications in many international and Greek industries. Some of the successful applications and products include:
Catalyst evaluation for petroleum refining processes
FCC catalysts evaluation
The technology developed in CPERI for the evaluation of FCC catalysts is based on a number of laboratory units (bench and pilot scale) by using proprietary evaluation protocols. The most important units used in this field are:
- FCC pilot plant
The FCC pilot plant is based on our own proprietary design and it uses a continuous circulated fluid bed reactor and consists of a riser, a stripper, a lift line and a fluid bed as the regenerator. The unit simulates a commercial FCCU aiming at catalysts evaluation and to the development of new technologies. - Laboratory unit for testing FCC catalysts (MAT)
The Microactivity Test (MAT) unit used in CPERI has been designed according to the ASTM D-3907. - Cyclic deactivation unit (CDU) for metals tolerance
The unit simulates the deactivation of FCC catalysts by exposing them in cycles: cracking, stripping and regeneration.
Methodology for FCC catalysts evaluation
The FCC catalysts evaluation is implemented by a combination of the above units. The method is based on a protocol applied to each unit. The type of protocol that will be used depends upon the special requirements of the refinery. For each catalyst, LEFH can give the yields and selectivities of all products as a function of conversion. In addition, the evaluation is completed by the physicochemical characterization of the cracking catalysts.
FCC additives evaluation
Apart from the above described technology, the Laboratory has also developed technology for the evaluation of some FCC additives: DeSOx and BCA (Bottom Cracking additives):
- Evaluation of DeSOx additives
A laboratory procedure has been developed in LEFH for testing the relative SOx-removal activity of various DeSOx additives. The procedure involves full cycles between SOx adsorption and regeneration of the materials, carried out usually at the conditions of a typical FCC unit. - Evaluation of BCA additives
BCA are now very important because of the higher amounts of resid added in the FCC feedstock. The technology developed in CPERI for BCA evaluation is based on the units described above for FCC catalysts. The CDU is the key unit for this evaluation (mettalation procedure) while the final evaluation is carried out in MAT or FCC pilot unit according to a specific protocol.
HDS catalysts evaluation
A special pilot plant unit is used for the evaluation of the various hydrotreating catalysts. The unit can operate in a wide range of operating conditions and for all petroleum fractions.
- Pilot plant unit for hydrotreating petroleum fractions (HDS) (click here for more details on this item)
The HDS unit consists of two reactors connected in series and contains three independent feed modules (H2, H2/H2S, N2). The unit is fully automated and can operate up to a maximum temperature of 550°C and up to a maximum pressure of 200 bar. - Methodology for HDS catalysts evaluation
A standard protocol is applied which depends on the type of catalyst, the type of feedstock and the targets of the hydrotreating process. The catalysts comparison is performed under constant operating conditions according to the degree of hydrogenation achieved by each catalyst.
