Description

General description

Propane is an aliphatic hydrocarbon obtained during the oil and natural gas processing. It is generally used as a fuel in automobiles and LPG. It serves as a raw material for the modern chemical industry.

Application

Propane can be used as:

• A substrate in the study of oxidative dehydrogenation using carbon nanofiber-based catalysts and zeolite catalysts.
• A component of a binary system along with CO₂ to study the solubility of some fat-soluble vitamins.

Packaging
