Investigation of the interaction of reactant molecules with catalyst surfaces is of vital importance in the design and efficiency of any catalyst or catalytic process. One of the most widely used techniques in this respect is the study of surface interactions under programmed temperature conditions. The advantages of this method are:
Areas of application:
Systems:
Industries: chemical industry, energy, environment/pollution, pharmaceutical industry.
The Heterogeneous Catalysis Laboratory is equipped with a TPDRO 1100 Series catalyst characterization apparatus, equipped with a thermoconductivity detector (TCD) (Thermo Scientific, USA), coupled with a quadrupole mass spectrometer (QMS) (PrismaPlus, Pfeiffer Vacuum, Germany). Thus, the experimental system is superior to the usual commercial apparatus because it combines the information obtained from two detectors, TCD and QMS, providing clearer and more comprehensive results.
INCDTIM offers RDI services for characterizing the active surface of catalysts, used alone or in combination with other solid characterization techniques (X-ray diffraction, optical, and electron microscopy), covering almost the full range of structural and functional characterizations.
Before entering into a contract-based relationship, we assist in defining the needs of the customer/partner as accurately as possible and, if required, we carry out preliminary tests free of charge.
Our existing equipment and experience allow us to characterize most materials with catalytic potential.
We have specialized staff in highly prestigious research centers abroad, able to cover at high standards all the stages of a contractual collaboration: defining the problem to be solved, experimental design, data collection, interpretation of the results, and their correlation with other complementary information, if necessary.
The cost of a determination is 300-350 lei/sample (depending on the complexity) and consists of
time spent using the equipment
labor, which includes personnel and indirect costs associated with sample preparation operations, analysis and interpretation of results, and preparation of the analysis/research report.
