This invention describes a novel and efficient processing scheme that can be used to transform a vacuum residue feedstock into 0.5 wt % sulfur bunker fuel that fulfills the specifications required by the International Maritime Organization (IMO).

Disclosed herein are carbon molecular sieves and methods of making the same through the pyrolysis of a polymer precursor in the presence of a reactive gas stream including a hydrogen source.

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.

The present invention relates to a mass for trapping silicon compounds, comprising a porous alumina-based support and at least one metal chosen from the metals from groups VIB and VIIIB, and exhibiting a grain density of at least 1.20 g/ml, a specific surface of at least 300 m.sup.2/g and pores with a mean size of less than 6.5 nm, as determined by mercury porosimetry. The present invention also relates to a process for the preparation of said trapping mass and to a trapping process using said trapping mass.

A process to remove H.sub.2S from a stream comprising the steps of adding a glyoxal, a silica nanoparticle composition, and optionally a triazine to the stream. The stream is selected from the group consisting of Oil streams, Gas streams, CO.sub.2 point source purification streams and Geothermal Energy System streams.
