| Abstract [eng] |
Anaerobic digestion of seaweed biomass produces energy products (biogas), which can be used for electricity generation, heat and biofuels. However, after anaerobic treatment in the bioreactor, a high–calorie biomass (digestate) remains. It can ideally be used as a fertilizer for the fields. However, the remaining biomass can be reprocessed to obtain the maximum amount of energy products. Also, seaweed absorbs not only minerals and beneficial substances during its life cycle, but also pollutants. As a result, biomass can be contaminated with heavy metals and its use for field fertilization is not possible. One of the most popular and promising ways to extract energy products is pyrolysis. Resins, gases and carbon are formed as products after this process. The aim of the presented master's project is to perform anaerobic treatment research to obtain a digestate and to investigate the thermal decomposition properties of a digestate. The obtained energy products (resins and gases) were investigated after the pyrolysis process. The resulting resins were found to contain compounds that could be used as fuel for recycling. After analyzing the composition of pyrolysis gas, it was determined that the main components of gas are CO2, CH4, H2 and CO. |
