POSSIBILITY OF IN SITU HYDROGEN GENERATION WITHIN GAS RESERVOIRS
Abstract
Recently, hydrogen is often considered as one of the prospective clean energy carriers. However, the traditional hydrogen production methods also produce significant amounts of greenhouse gases or too expensive to be industrial scaled. In situ hydrogen generation in hydrocarbon-containing reservoirs can be one of the promising ways for low-carbon hydrogen production. However, the conversion of hydrocarbons into hydrogen under the hydrocarbon reservoirs conditions has practically not been studied. This work reports experimental results on the catalytic in situ hydrogen generation from methane under gas reservoir conditions. Verification concept experiments were performed in the autoclave setup in static and dynamic modes with various operational parameters. The effects of temperature, pressure, and core model type on the hydrogen generation were investigated. Results show that temperature higher than 550?C should be achieved in the active zone of the target reservoir to convert significant amount of methane to hydrogen. This effect can be explained by the thermodynamic restrictions and negative influence of the original core on catalyst activity. Nevertheless, hydrogen concentrations up to 70.8% mol. and 34.0% mol. were achieved in the experiments at 800 ?C in the presence of the inert (crushed alumina) and the original core models, respectively. At this temperature strong reducing conditions influence the catalyst activity. Conducted experiments proved the main principles of the in situ hydrogen generation technology. Therefore, we conclude that hydrogen generation in gas reservoirs is prospective when realized jointly with the catalyst treatment and in situ combustion method.
