The present subject matter describes a method for preparation of a lubricant dispersed with carbon nanotubes (CNTs) and a lubricant dispersed with the CNTs prepared thereof. The method comprises ball milling the CNTs and purifying the ball milled CNTs to remove impurities in the CNTs. The method also comprises oxidizing surfaces of the purified CNTs by adding the purified CNTs to a solution comprising at least one oxidizing acid and then refluxing the solution. The oxidized surfaces of the CNTs are modified by adding the CNTs to a solution comprising at least one fatty acid to obtain surface modified CNTs. The method also comprises dispersing the surface modified CNTs in a lubricant to obtain the lubricant dispersed with CNTs.

Lubricant dispersed with carbon nanotubes

In accordance with the present subject matter there is provided a process for catalytic decomposition of lower hydrocarbons to produce carbon oxides free hydrogen and bamboo shaped carbon nanotubes over a catalyst composition. The process for catalytic decomposition of lower hydrocarbons comprises contacting lower hydrocarbon over a catalyst composition, where the catalyst composition comprising, a catalyst, at least one modifying agent and a support material.
