naphthenes meaning in Hindi

Examples

1. However, both the dehydrogenation of naphthenes and the dehydrocyclization of paraffins produce hydrogen.
2. It can be seen that they differ significantly in their content of paraffins, naphthenes and aromatics:
3. The product stream is high in naphthenes and aromatics, low in paraffins and very low in olefins.
4. The products of this process are hydrocarbon chains as well as adding hydrogen to aromatics and olefins to produce naphthenes and alkanes.
5. Paraffin waxes are mixtures of saturated n-and iso-alkanes, naphthenes, and alkyl-and naphthene-substituted aromatic compounds.
6. The different fractions can be passed to further processing ( Platforming, most of the naphthenes are converted to aromatics and the recovered hydrogen recycled to the process.
7. JP-5 is a complex mixture of hydrocarbons, containing alkanes, naphthenes, and aromatic hydrocarbons that weighs and has a high flash point ( min . ).
8. More advanced processes, such as cyclicization of paraffins and dehydrogenation of naphthenes forming aromatic hydrocarbons in a catalytic reformer, have also been developed to increase the octane rating of gasoline.
9. :1 : The dehydrogenation of naphthenes to convert them into aromatics as exemplified in the conversion methylcyclohexane ( a naphthene ) to toluene ( an aromatic ), as shown below:
10. If the raw material stream contains much non-aromatic components ( paraffins or naphthenes ), those are likely decomposed to lower hydrocarbons such as methane, which increases the consumption of hydrogen.
