Platform for H2 production from waste biomass with inherent negative emissions

C3H8O3 is the main byproduct of biodiesel production, accounting for 10wt% of the final products[1]. This work proposes a system for converting this waste C3H8O3 made from biomass into H2 or other syngas-derived chemicals.
This is carried out using a chemical looping reactor which provides the heat required to reform the glycerol while having inherent CO2 capture. This is achieved using dynamically operated packed bed reactors. The heat required
to drive the reforming process is produced from the indirect oxyfuel combustion of biogas or offgas from downstream processes through the use of a chemical intermediate as represented in Figure 1[2]. This produces first N2 and then a mixture of CO2 and H2O which are easily separated for CO2 sequestration. As the C3H8O3 is from a biological source this gives the system the potential for negative emissions.
Then the reforming stage occurs, where the C3H8O3, H2O and CO2 are fed to the reactor producing syngas and cooling the bed to the initial solid temperature.
