Abstract:

The diminution of the deterioration of the road infrastructure and the prevention of the appearance of phages is realized by modifying the road bitumen with polymers of elastomeric type that ensures the elastic return of the asphalt. The aim of the project is to develop an innovative technology on an industrial pilot scale for the manufacture of an elastomer for the modification of road bitumen by devulcanizing the used rubber powder. The innovative character of the project proposal is given by the proposed method for the devulcanization of spent rubber, respectively slow catalytic pyrolysis in the presence of an acid nanostructured catalyst, and the reactive adsorption of the sulfur resulting on nanostructured adsorbents. The improvement of the thermal and mass transfer in the extruder type pyrolysis reactor and implicitly the reduction of the temperature gradient, will be achieved by the use of an aromatic petroleum solvent, with low volatility, solvent that will solubilize the desulfurized elastomer. The metal sulfides resulting from the reactive adsorption will be removed by extraction in a polar solvent. By applying the procedure from this project proposal there is no toxic waste or gas, and the process of modifying the road bitumen will be simplified.

Abstract:

The present research proposal aims to obtain high value products (antioxidants, lipids and carbohydrates) from microalgae biomass using the concept of biorefining. A first stage of this project consists in optimizing the growth conditions of two microalgal strains (Porphyridium purpureum and Dunaliella salina), in order to maximize the content of antioxidants, lipids, carbohydrates, using statistical methods of programming experiments. The second stage refers to comparing the efficiency of conventional and unconventional extraction methods (supercritical carbon dioxide extraction, ultrasound-assisted extraction and classical solvent extraction) in recovering from wet algal biomass antioxidants and lipid fraction with a high content of fatty acids polyunsaturated (compounds for use in the pharmaceutical industry). In a third stage, the fractions of lipids rich in polyunsaturated fatty acids and carbohydrates from algal biomass will be transformed into ethyl esters of unsaturated fatty acids and levulinic acid respectively. In order to achieve this transformation, the development of a heterogeneous ferromagnetic acid catalyst is envisaged to ensure the development of these high efficiency processes. By adopting the concept "zero waste, the project aims to convert the exhausted biomass from active principles into biocarbons with adsorbent properties, which will be tested for the retention of inorganic compounds. The content of the project includes innovative multidisciplinary activities for optimizing the growth conditions of microalgae, respectively for extracting the compounds of interest, and for their efficient transformation into high value added compounds using catalytic systems developed within the project.

Abstract:

The purpose of this project is to develop the post-combustion chemical absorption of carbon dioxide by testing new physico-chemical solvents hybrid amine-deep eutectic solvents (DES). In this project, at least three types of amine eutectic hybrid solvents, (ChCl-MEA), (ChCl-DEA) and (ChCl-MDEA) will be used. Through experimental and modeling-simulation studies, the validation of the CO2 capture post-combustion technology in the case of its integration in the circulating fluidized bed combustion (CFBC) technology using fossil fuels such as lignite will be conducted. At the same time, it is desired to identify CO2 sequestration solutions by developing algae culture that are characterized by an absorption capacity of 15-20 times higher than the usual plants. The overall objective of the project is to develop the technological maturity level (from TRL 3 to TRL 4) up to the laboratory scale of the CFBC plant provided with post-combustion CO2 capture through chemical absorption belonging to the „CO2 Capture Technologies” laboratory from the Power Engineering Faculty from University Polytechnic of Bucharest. Optimization and validation of CO2 chemical absorption technology will focus on: reducing the energy penalty; solvent flow minimization (L/G ratio); increasing the absorption capacity of the hybrid amine-DES solvent; diminish of solvent losses in the absorption-desorption columns; evaluation of economic indicators CAPEX, OPEX, the levelised cost of electricity as well as the cost avoided with CO2 emission. Together with the coordinator of the Polytechnic University of Bucharest, the consortium also includes the partner ICECHIM - the National Research and Development Institute for Chemistry and Petrochemistry recognized for its experience in the development of chemical, physical solvents and respectively the development of algae cultures for CO2 sequestration.

Abstract:

The complex project propose the development and demonstration of innovative technologies to optimize the biogas plants by integrating the open ponds for microalgae cultivation using the digestate resulted from anaerobic digestion as a culture medium. The integral valorization of microalgae biomass consists in: obtaining of algal extracts (for co-digestion), lipid fraction (for biofuels) and spent biomass (co-digestion substrate); advanced separation and valorization of biogas by carbon dioxide conversion to biomethane; biorefining of the solid digestate and lipid fractions obtained from algal biomass into biochar, fuel components, bitumen fluxes, biohydrogen and liquefiable gaseous fractions. As results of this project will be: a demonstrated technology at TRL 6 level within the biogas-microalge integrated and an experimental stand for the evaluation of biomethane and liquefied gaseous hydrocarbons combustion efficiency and emission control.
