This Southern Research Institute project will design, build, and test a novel steam reforming catalyst for converting tars and methane under high temperature and sulfur environments to increase the H2:CO ratio of a surrogate low-rank coal syngas. This will be performed at a lab-scale. This work is intended to demonstrate the potential commercial viability of catalytic steam reforming under severe contaminant environments to produce a cost-effective high H2 syngas from low-rank coals.
Southern Research will design and analyze a modified, advanced gasification platform for the conversion of low-rank coals to syngas for coal-to-liquid and gasification combined cycle applications. Specifically, this will involve development, testing and optimization of steam-reforming catalysts for converting tars, C2+ hydrocarbons, NH3, and CH4 in high-temperature and sulfur environments, typical of syngas from low-rank coal gasification. Improved catalysts would increase the H2:CO ratio of the syngas and reduce down-stream fouling costs and efficiency losses, which would support the commercialization of a high-temperature, sulfur-tolerant steam reforming catalytic process to reduce the cost of coal-based gasification cleanup, reduce carbon emissions and increase the efficiency of low-rank coal gasification for production of electricity and coal-to-liquids.
