The present disclosure related generally to a process for removing chloride-containing organic compounds from renewable and bio-feedstocks. Accordingly, in one aspect, the present disclosure provides for a process for processing a liquid feed, the process comprising: providing a liquid feed that comprises one or more fatty acids and/or fatty acid esters, the liquid feed having a first chloride concentration by weight of chloride-containing organic compounds; and contacting the liquid feed with a solid treatment material to remove at least a fraction of the chloride-containing organic compounds to produce a treated liquid feed having a second chloride concentration that is less than the first chloride concentration, wherein the solid treatment material comprises an alkali metal or an alkaline earth metal in ionic form.

The present invention concerns an adsorbent comprising at least one zeolite selected from a zeolite of the 12 MR, 10 MR and 8 MR type and at least one binder comprising a clay with a Si/Al weight ratio of more than 2. It also concerns its preparation process and its use in a process for purifying a hydrocarbon feed comprising unsaturated molecules and at least one impurity comprising at least one heteroatom of the O, S or N type.

The present disclosure provides a method for removing sulfur compounds from a fuel containing sulfur compounds. The method includes contacting the fuel with an adsorbent that comprises a carbonaceous material doped with nanoparticles of aluminum oxide to reduce the concentrations of the sulfur compounds. The carbonaceous material is at least one selected from the group consisting of activated carbon, carbon nanotubes, and graphene oxide, and the adsorbent has a weight ratio of C to Al in the range from 3:1 to 30:1, and a weight ratio of C to O in the range from 1:1 to 10:1.

The invention relates to a method for cleaning hydrocarbon mixtures, in which a contaminated hydrocarbon mixture comprising hydrocarbons having three to eight carbon atoms is at least partly freed of impurities by contacting with a solid sorbent, wherein the hydrocarbon mixture is exclusively in the liquid state during contact with the sorbent. The object of the invention is to specify a process for cleaning liquid C.sub.3 to C.sub.8 hydrocarbon mixtures, which is based on a readily available but non-carcinogenic sorbent and which achieves better purities compared to traditional molecular sieves. This object is achieved by using, as sorbents, solid materials of the following composition: copper oxide: 10% to 60% by weight (calculated as CuO); zinc oxide: 10% to 60% by weight (calculated as ZnO); aluminum oxide: 10% to 30% by weight (calculated as Al.sub.2O.sub.3); other substances: 0% to 5% by weight. Materials of this kind are otherwise used as catalysts in methanol synthesis.

A process is presented for the removal of contaminants like oxygenates from hydrocarbons. The contaminant oxygenates are removed from hydrocarbons that may be feed to cracking units. A crude feed stream is fed to a water wash column along with water to remove oxygenates and is subsequently treated with an adsorbent to effectively remove all the oxygenates from the crude hydrocarbon. A regenerant medium from a naphtha hydrotreating unit is used to regenerate the adsorbent.

This present disclosure relates to processes and apparatuses for removing contaminants from hydrogen streams. More specifically, the present disclosure relates to processes and apparatuses wherein hydrogen is used in units that utilize catalysts that are sensitive to oxygenates. The contaminants like carbon oxides and water are removed simultaneously from the hydrogen stream to provide a rich hydrogen stream with high purity to units that utilizes catalysts that are sensitive to oxygenates.
