Research Interests
Chemical Looping Systems
One of the new applications of fluidized bed reactors is Chemical-Looping Combustion, CLC, which produces power by connecting two fluidized beds: a fuel reactor and an air reactor. In this configuration, air is never mixed with fuel. Instead, a metal oxide supplies the oxygen required for fuel combustion. It circulates in a loop, connecting the air reactor and fuel reactor. This novel configuration prevents NOx formation, and produces pure stream of steam and CO2, from which CO2 is separated without energy or economic penalty.
In another system, sorbent moves around the two interconnected fluidized fuel and reactor beds capturing CO2 in a gasification/carbonation cycle. Biomass gasifier with Calcium looping cycle can increase gas efficiencies and lead to negative carbon emissions.
Biomass Utilization
The thermochemical process of biomass can lead to generation of heat, electricity and/or biofuels. Biomass has the potential of to generate carbon-neutral energy. Current projects include biomass gasification with catalytic tar reduction; biomass pyrolysis; and utilization of pyrolysis products (bio-oil and biochar).
