Witryna14 sie 2024 · Low-range hydrocarbons (LRH) – for carbon range ≥C 5 – Petroleum naphtha is an intermediate hydrocarbon liquid stream derived from the refining of crude oil with CAS-no 64742-48-9. It is most usually desulfurized and then catalytically reformed, which rearranges or restructures the hydrocarbon molecules in the naphtha as well as breaking some of the molecules into smaller molecules to produce a high-octane component of gasoline (or petrol). There are hundreds of different petroleum crude oil sources worldwide and each crude oil has it…
