He received his MSc from Volgograd State Technology University in Russia in 1997, and then worked for a number of years before joining the team of researchers and engineers working on a project involving the design, construction and optimization of a Fluid Catalytic Cracking (FCC) pilot plant for joint polymer-Vacuum Gasoil (VGO) procesing in Alicante, Spain. He specializes in mathematical programming methods for the modelling, design and optimization of chemical processes and the study of polymer recycling as an alternative fuel source.

2. Abstract In this work, we investigated the joint processing of blends of Vacuum Gasoil and polymer (polyolefin) wastes in conventional industrial Fluid Catalytic Cracking (FCC) Units as an alternative route to the energy and chemical revalorisation of these wastes. Termogravimetric (TG), Differential Scanning Calorimetry (DSC) and rheological analysis as well as physico- chemical characterization (density, surface tension, melting and boiling peak temperatures, chemical composition) of the VGO-Polymer wastes feedstock were performed at laboratory scale. The results of these analysis has been used at the design stage and scale-up to determine the operating conditions of a built FCC pilot plant at the University of Alicante, Spain. Overall test runs performed showed the viability of the process and the ability of this pilot plant to successfully convert VGO-polymer feedstocks to gasoline, light hydrocarbon gases and other petrochemical feedstock in a conventional FCC unit. The influence of the operating parameters and polymer concentrations of up to 10% wt. in the feed on the different compositions of the catalytic cracking products, specifically gasoline and the C2-C4 gas fraction, has also been investigated. It was found that an increase in the polymer fraction in the feed leads to an increase in the liquid and a decrease in the gas fraction of the obtained product. The optimal feed/catalyst ratio was 1/7 using an equilibrium FCC catalyst.
