    Abstract

    The effect of jet fuel manufacture processes on thermal stability quality is discussed in general terms. Processing sequences used to prepare jet fuel blend stocks vary widely depending on factors such as overall refinery design and crude type, and can have a significant effect on thermal stability quality. Processes which remove compounds which have a deleterious effect on thermal stability such as reactive olefins and heteroatom compounds have the greatest potential for thermal stability quality enhancement. Thus, hydrocracking and hydrotreating processes, in general, have greater potential for producing blend stocks with higher thermal stability quality than sweetening processes which convert mercaptans to disulfides which are left in the jet fuel. Treating with adsorbates such as Attapulgus clay also has the potential to remove deleterious compounds.
