What is Production of an iron-loaded carbonaceous material through pyrolyzing biomass impregnated with FeCl2 about?

We propose a novel method for preparing iron-dispersed carbonaceous materials by utilizing low-grade materials and waste heat. Iron is loaded into the biomass through stirring it in a solution of FeCl 2 for 2 h and then pyrolyzed at 600-900 °C to prepare materials composed of iron and carbon. Further in order to investigate the reactivity of the sample, steam and CO 2 gasifications of the material was performed at 800-900 °C. Approximately 80% of the carbon in the biomass remained in the solid state during pyrolysis at 600 °C because of the effect of FeCl 2 in promoting the carbonization of the biomass. The prepared material displayed high reactivity during gasification due to the catalytic effect of loaded iron. This result indicated the possibility that the composite may be used as an iron and heat source for a steel converter. Furthermore, the high reactivity of the composite during steam gasification suggests its usefulness as a medium for hydrogen or carbon monoxide production.
