Abstract
The paper presents ways to reduce the carbon footprint through the reuse of microalgae biomass as biofuel (related to bio-CCU). Processing of microalgae biomass into biochar is used for carbon sequestration, raw material for the production of thermal energy, as well as activated carbon and adsorption of toxic compounds from polluted air, water and soil. Biofuels are considered carbon neutral because the CO2 released after they are burned is used by plants and algae for photosynthesis, which leads to carbon dioxide fixation. Obtaining energy by burning carbonized biomass of microalgae is based on the effect of carbon dioxide neutralization, which significantly distinguishes this method from known traditional methods, and does not cause environmental pollution with greenhouse gases. The results of complex thermogravimetric and differential thermal analyzes of the calorific value of biochar based on the biomass of chlorophyll-synthesizing microalgae Chlorella vulgaris obtained as a result of the sorption of greenhouse gases formed during the burning of solid, liquid or gaseous fuels.It was established that the biomass of microalgae obtained by absorbing carbon dioxide, a product of fuel combustion with sulfur dioxide impurities, has a greater heat-generating capacity compared to the biomass obtained by absorbing pure carbon dioxide. Combustion of microalgae biomass, which contains sulfur compounds in the internal volume of cells, which are formed as a result of the metabolism of sulfur dioxide, is accompanied by more significant exothermic effects. According to the results of thermal studies, it was established that the heat-generating capacity of such microalgae biomass exceeds the heat-generating capacity of aspen (Populus tremula), which is an alternative source of energy in the territory of Ukraine, and is close to the heat-generating capacity of the selectively bred energetic willow (Salix Viminalis).
