  • Publication number: 20240036025
    Abstract: Processes for quantitating the corrosivity of naphthenic acids in a sample comprising crude oil or a liquid fraction thereof by reacting the sample with a metal comprising iron to produce iron naphthenates that are then stabilized by a ligand. The stabilized iron naphthenates are then analyzed by mass spectrometry to accurately quantitate the percentage of total naphthenic acids in the sample that are iron-reactive naphthenic acids associated with metal corrosion.

  • Publication number: 20230048135
    Abstract: Embodiments of the present disclosure generally relate to methods for preparing carbon materials which can be used in battery electrodes. More specifically, embodiments relate to methods for preparing nano-ordered carbon products used as anode materials in metal-ion batteries, such as a sodium-ion battery. In some embodiments, a method includes fractioning an initial refinery hydrocarbon product during a fractionation process to produce a liquid refinery hydrocarbon product and a heavy refinery hydrocarbon product. The method includes exposing either or both refinery hydrocarbon products to a first functionalization agent to produce a first solid functionalized product during a first functionalization process and purifying the first solid functionalized product during a purification process.

  • Publication number: 20230011703
    Abstract: A process for decreasing contamination of a commercial refining process by vanadyl porphyrins and/or nickel porphyrins by allowing rapid screening of porphyrins directly from asphaltenes isolated from crude oil without enrichment by use of positive-ion electrospray ionization mass spectrometry (ESI MS). Sodium formate is utilized as a ESI spray modifier. The vanadyl porphyrins are detected predominantly as sodiated species, while nickel porphyrins are observed as both sodiated species and molecular ions. Crude oil feedstocks exceeding a defined threshold concentration of vanadyl porphyrins and/or nickel porphyrins are rejected or diluted prior to utilization as refinery feedstock. Certain embodiments additionally quantitate both deoxophylloerythroetioporphyrins and etioporphyrin content (and their ratio) to predict crude oil thermal maturity.

  • Patent number: 10519385
    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.

  • Publication number: 20150219615
    Abstract: The present disclosure relates generally to processes for accurate quantitation of naphthenic acids in liquid samples. The method allows efficient identification as well as quantitation of NA species based on carbon number and ring structure, but requires no chemical modification or extraction of the sample allowing a rapid throughput. Reverse phase liquid chromatographic separation of the sample minimizes (or eliminates) matrix suppression effects to allow detection of all NAs present in various samples by mass spectroscopy with superior detection thresholds that are as much as 350-fold lower than conventional methods.
