Kinetic Modeling of a Conceptual Hydrogen Production Plant for Regional Hydrogen Resiliency

Abstract The current article explores a conceptual hydrogen (H2) production plant with an integrated gasification combined cycle (IGCC) designed in a commercially available simulation software to meet the auxiliary power requirements of the plant and a portion of the local electricity demand. A kinetic reactor model was used to carry out the gasification reactions. A major goal was to understand the capability of locally available feedstocks in El Paso, TX, such as pecan shells, cotton gin trash, and MSW, in hydrogen production. Both single feedstock gasification and co-gasification (municipal solid waste and pecan shell blend) methods were investigated to observe feed sensitivity to hydrogen production. A process parametric sensitivity analysis is conducted, primarily focusing on equivalence ratio and temperature. Initial results show that a lower equivalence ratio (ER) provided more H2 and CO yield and then decreased as ER increased from 0.18 to 0.36. However, a slightly different trend is seen when cotton gin trash (CGT) is used as feedstock. The sensitivity study found that the highest H2 yield was from pecan shell gasification at 950°C temperature. Additionally, co-gasification of pecan shells and MSW provided better syngas yield results with approximately 31% H2 and 32% CO, respectively, compared to only MSW gasification.
