The results indicated that the greenhouse gas emission, especially for the CO 2 and CH 4 , showed a distinctly spatial variation.
While this is a significant component, the CH4 associated with imported embodied energy should also be included in national greenhouse gas (GHG) inventories.
The experimental results indicated that isobutane was formed by a propane intermediate and isobutyraldehyde was formed by a propionaldehyde intermediate in the reaction.
The greenhouse with CO2 supplied from bottles turns out to be superior to tthe greenhouse with CO2 supplied by burning gas.
Furthermore, in a range of temperatures and pressures, the affinity of Cu-BTC for isobutane was observed to be intermediate to that of propane and propylene which suggest that isobutane is a promising desorbent in SMB processes for propane/propylene separations.
Evidently hydrogen transfer is more important in the conversion of isobutane than of neopentane.
Isobutane presents a smaller sensitivity to residence time than other investigated hydrocarbon systems.
Dehydrogenation of saturated isobutane provides an alternative process to produce isobutene from nonpetroleum resources.
