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 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.
