Future Research

The focus of current and future research will be based on our most recent results obtained under ongoing NSF grants. Those results include data from the all-vapor gas-hydrate instant- formation method which we have extended in three particular directions:

1. Extensive but incomplete data are now available in the 200 K to 220 K temperature range; a result of an effort to move this potentially powerful method towards temperatures and pressures more appropriate for practical applications.

2. The identification of new catalysts to aid in the search for sampling conditions that allow minimization of the amount of catalyst required in the all-vapor mixtures of the instant-formation. Small ether molecules continue to be the best catalysts tested but methanol, Cl2, SO2, H2S and methyl chloride, when used alone or mixed with other guest molecules, have been found to have profound effects that will guide new research.

3. Guidance will also come for future research from extensive new data that indicate the impressive level to which important gas molecules, in particular CO2, CH4 and acetylene, are trapped at modest pressures in solvent droplets formed rapidly from homogeneous nucleation near 220 K.
