The hypothetical polyethylene melt at room temperature is of interest for the purposes of developing the atomic level modeling of gas solubilities in rubbery polymers. In the present study, the gas solubilities in completely amorphous polyethylene are predicted by extrapolating alkane behavior to the long chain limit in a Flory−Huggins context. The results are seen to agree well with a recent simulation study.

Platinum-loaded NaY zeolite (Pt/NaY) catalysts were synthesized and tested for the aqueous-phase reforming (APR) of methanol and ethanol solutions to produce hydrogen. The APR performance of the Pt/NaY catalysts was compared to the conventional γ-alumina-supported platinum (Pt/γ-Al 2 O 3 ) catalysts. The results have shown that the Pt/NaY catalysts have higher catalytic performance for the APR of methanol and ethanol than the Pt/γ-Al 2 O 3 catalysts.
