High‐temperature hydrocarbons (HTHs) are also known as high molecular weight hydrocarbons (HMWH). HTHs are derived naturally as well as through synthesis. The former are paraffinic base hydrocarbons that are obtained from petroleum crude similar to mineral oils, except fractioned from higher levels of distillation. The latter are developed through polymerization of olefins and hence are called as polyalpha olefins (PAO) [27]. These liquids are also known as high fire point liquids.
