Noble Metal Catalysts. Rh-based catalysts have been investigated on different supports, resulting in different H2 and CO yields. Gasoline and naphtha POX over a supported Rh catalyst were reported by Fujitani et al. For y-alumina supported Rh catalyst, maximum yields of 96% of both H2 and CO were reported with 0.2 wt% Rh loading at 700°C, an air equivalence ratio of 0.41, and a liquid hourly space velocity (LHSV) of 2 h A 0.05 wt% Rh supported on zirconia yielded 98% H2 and 85% CO at 725°C, an...

Incorporation of these heterocycles into poly(dienes) has pronounced effects on polymer solubility. Solubility in oxygenated solvents, especially ketonic solvents, increases whereas solubility in hydrocarbon solvents decreases dramatically. This has led to applications requiring resistance to swelling in oil, gasoline and naphtha. 

Benzine an obsolete term for light petroleum distillates covering the gasoline and naphtha range see Ligroine.

The Kuwait crude-petroleum sample, obtained from Dr. D.F. Duckworth (B.P. Ltd.), was distilled up to 192° under ordinary pressure to separate off straight-run gasoline and naphtha (b.p. 32-190°C). The naphtha-free degassed oil distillate was then vacuum-distilled on a molecular still, successively at 90° and 1.8 Torr, 130° and 0.9 Torr, and 130° and...

Catalytic reforming processes gasolines and naphthas from the distillation unit into aromatics. Four major reactions occur dehydrogenation of naphthenes to aromatics, dehydrocyclization of paraffins to aromatics, isomerization, and hydrocracking. 

Gasoline and naphtha ASTs the shell plates and floating roofs suffer from severe electrochemical corrosion in the presence of dissolved water and oxygen.
