PETROCAT Private Company (P.C.) is a spinoff of the Center of Research and Technology - Hellas and it is set up to promote technology developed by the Chemical Process and Energy Resources Institute (CPERI) and more specifically by the Laboratory of Environmental Fuels and Hydrocarbons (LEFH) and the Laboratory of Process Systems Design and Implementation (PSDI).

The Laboratory of Environmental Fuels and Hydrocarbons undertakes applied research in the area of hydrocarbons and it is in a position to provide technical services to the petroleum industry. LEFH focuses on developing petroleum refinery technology applications for various refinery and bio-refinery processes. Moreover, it deals with environmental processes which are related with the fuels (DeSOx, DeNox). The Laboratory of Process Systems Design and Implementation (PSDI) carries out research among others in the design, construction of complex process systems.

PETROCAT aims at providing services mainly to petroleum refineries, with the objective of offering practical solutions to existing refinery problems. By combining catalyst evaluation data with the current operation of commercial FCC units, and drawing on decades of experience in constructing and operating pilot units in CPERI's high-bay area, PETROCAT supports refineries, bio-refineries, catalyst suppliers and licensors, from catalyst and feedstock selection to process optimization, scale-up studies and the design and start-up of pilot plants for new fuel and energy technologies.
