Hydrogenation general terms

Compounds containing only carbon and hydrogen are termed paraffins or alkanes. The general formula for these compounds is C H2n+2 where n is an integer. When only single bonds are present between carbon atoms they are classified as saturated . Examples include, etliane, propane, and butane the last two are common fuel gases ... 

The essence of the process is the precipitation of ammonium peroxotantalate or peroxoniobate by the addition of solutions of ammonia and hydrogen peroxide, H2O2, to appropriate strip solutions. The process was described in general terms as follows ... 

Naphtha is the general term that is applied to refined, partly refined, or unrefined low-boiling petroleum products. Naphtha is prepared by any one of several methods, including (1) fractionation of distillates or even crude petroleum, (2) solvent extraction, (3) hydrogenation of distillates, (4) polymerization of unsaturated (olefinic) compounds, and (5) alkylation processes. Naphtha may also be a combination of product sfieams from more than one of these processes.

In general terms, it is expected that decarbonizing hydrogen made from natural gas or coal will increase the production cost by between 50 and 75%. Hydrogen gas that is produced conventionally (with CO emitted to atmosphere) costs about twice as much as natural gas or oil and about three times more than coal. 

The general term usually applied to the process of converting liquid or gaseous light hydrocarbon fuels to hydrogen and carbon monoxide is reforming.
