The present study dealt with the problem of waste formation which is a mixture of liquid, solid and gas materials in the liquefied gas containers through their maintenance process at the gas-fuel station. The waste from the cooking gas containers was analyzed using a Gas-Mass Chromatography (GC-MS) and an Infrared Spectrophotometer-Fourier Transform (FT-IR) to find out their components and then treat them using solid catalyst of calcined nano bentonite clay over reaction time (24 and 48 hours) with convenient stirring. The calcined nano bentonite clay has a high oxidative-catalytic ability to break down hydrocarbons into shorter chains due to the possession interchangeable protons distributed through clay surface and that led to new production of dominant hydrocarbon with longer chains such as (2-Furanol, tetrahydro-2,3-dimethyl-, trans) that amounted to (74.09⁒) of the total summit area, due to its high surface area, high dispersion, and converting all produced hexane (49.35%) over reaction time (24 hours). The results showed that the use of solid catalysts had a clear role in treating these wastes cleanly and converting them into other chemical forms that could be used if they were exploited industrially.
