Comparative assessment of various gasification fuels with waste tires for hydrogen production

In this paper, waste tires are comparatively studied and assessed as a feedstock relative to coal and coconut char. An Integrated Gasification Combined Cycle (IGCC) is developed by using the Aspen Plus to assess the suggested gasification feedstocks based on their carbon dioxide emissions and hydrogen production to feed rate ratios. Note that many tires are disposed of every year in North America and are stockpiled in the masses in landfills, which cause various environmental implications. In the present study, it is found that waste tires as a feedstock for gasification are a viable solution to this ever-rising problem. The hydrogen production to feed rate ratio is found to be 0.158 which is very competitive with high-quality coals and coconut char. The net power production from the combined cycle when tires are used as the feedstock for the gasifier is found to be 11.1kW. The optimal hydrogen production to feed rate ratio is also achieved at the maximum net power production rate. The energy and exergy efficiencies of the overall system are found to be 55.01% and 52.31% when the waste tires are used as a feedstock.     

Zn,S, N self-doped carbon material derived from waste tires for electrocatalytic hydrogen evolution

Developing multielement doped carbon material (CM) is extremely meaningful due to the synergistic regulation on electronic and molecular structure, which can endow catalysts with high electrochemical properties. However, it is a challenging issue owing to the complex and difficult preparation process. Herein, a novel waste tires-derived Zn, S, N self-doped CM is prepared and used for efficiently electrocatalytic hydrogen evolution reaction (HER). The electronic state and molecular structure are effectively adjusted by forming C–N and C–S bonds in CM, and the Zn 3d configuration could participate in molecular orbital hybridization to produce the synergistic effect with regulation of N and S, thus improving the electrocatalytic HER activity. The obtained Zn, S, N self-doped CM requires only an overpotential of 50 mV at 10 mA cm^?2, which is close to that of Pt/C (42 mV). The cell voltage of Zn, S, N self-doped CM || RuO₂ electrolyze (1.31 V) at 10 mA cm^?2 is much smaller than that of Pt/C || RuO₂ (1.46 V). This work points out a promising strategy for the development of multielement doped CM applied in electrocatalytic HER and the efficiently resourceful utilization of waste tires.
