This means that 1 gm of water requires 4.2 joules of energy to raise 1 degree Celsius. A 1.678 g sample of a component of the light petroleum distillate called naphtha is found to yield 5.143 g CO2 (g) and 2.456 g H2O (l) on complete combustion. Naphtha is a mixture of liquid hydrocarbons ranging from octane 814 to tetradecane 1430. But he has derived a new measure called "specific heat.

Cracked Naphtha (from a Coker or FCC) will generally have a much greater fouling factor than say virgin naphtha. It also contains in its composition naphthenic (cycloalkane) and aromatic (arena) hydrocarbons and impurities, including sulfur. Definition The specific gravity of naphtha is the ratio of the density of naphtha to that of a reference substance (Usually water). Naphtha is a liquid hydrocarbon mixture which is said to be highly flammable. All sampling instructions above are recommended guidelines for OSHA Compliance Safety and Health Officers (CSHOs), please see the corresponding OSHA method reference for complete details. The typical reforming catalyst is Pt supported on alumina [ 5 ]. Specific Gravity (60F): 0.73-0.76. Naptha (also called naphtha, heavy gasoline or fraction benzidamina) flammable liquid mixture of hydrocarbonsheavier than gasoline obtained by direct distillation of crude oil and gas condensates or cracking of petroleum products.
