Abstract: Spent zeolite equilibrium catalyst from the fluidized catalytic cracker has a useful function as an adsorbent for jet fuel. Redirecting such spent catalyst saves costs for refinery operations in two ways. The first is by avoiding the costs for disposing of such catalyst as hazardous waste. The second is to reduce the cost of procuring sorbent for the jet fuel decontamination process. Since zeolite is primarily silica and conventional sorbents are also silica, zeolite catalysts are chemically similar. And the equilibrium catalyst may be regenerated in the FCC after its becomes saturated with jet fuel contaminants and re-used.

Abstract: The present disclosure relates to a novel GC/MS/MS method for quantifying levels of elemental sulfur in hydrocarbons, including crude petroleum, petroleum products, and liquefied hydrocarbon gases.
