Biomass gasification is a revolutionary technology that turns waste into a clean source of energy. It provides a novel means of lowering waste, lowering emissions, and raising sustainability by turning organic resources into syngas.
SIMULATION OF POLYOLEFINS WASTE GASIFICATION FOR CHEMICAL RECYCLING APPLICATIONS IN ASPEN PLUS
INFLUENCE OF INDIRECTLY HEATED STEAM-BLOWN GASIFICATION PROCESS CONDITIONS
ON BIOCHAR PHYSICO-CHEMICAL PROPERTIES
By 2050, the Dutch government wants to recycle all of their plastic waste. Plastic waste can be used as a source for valuable chemicals to be recovered using procedures like gasification. To enhance carbon conversion efficiency, cold gas efficiency, product gas yield, and tar yield, the TU Delft Process and Energy Department is creating a kinetic model of the Indirectly Heated Bubbling Fluidized Bed Steam Reformer. The model determined the best temperature, equivalency ratio, and steam-to-fuel ratio for gasification. The customizable model can be applied to further enhance gasification for recycling plastic waste.
The study examines how temperature and the gasification agent affect the properties of biochar generated using an unique 50 kWth Indirectly Heated Bubbling Fluidized Bed Steam Reformer. According to the findings, indirect gasification creates high-quality biochars with improved porosity, a high heating value, and aromaticity. The highest yield of biochar and the best syngas composition are produced by air/steam gasification under specific conditions. Indirectly heated biochars can increase agricultural production and CO2 adsorption and are in accordance with the European Biochar Certified. The innovative indirect design has the potential to enhance gasification circularity.
