  • Patent number: 9012712
    Abstract: An adsorption process is disclosed for removal of acid gas contaminants from a liquid or gas which comprises providing an activated alumina adsorbent which is impregnated with a compound selected from the group consisting of one or more alkali metal compounds, one or more alkaline earth metal compounds, or a mixture of such compounds; contacting the liquid or gas containing acid gas contaminants with the activated alumina adsorbent to adsorb enough acid gas contaminant in the liquid or gas to lower the contaminant content of the liquid or gas, the alumina adsorbent being formed from agglomerated calcined alumina powder and provided with a mercury pore volume of pores greater than 500 angstroms at least 0.10 cc/g.

  • Patent number: 7857965
    Abstract: A process for upgrading hydrocarbonaceous oil containing heteroatom-containing compounds where the hydrocarbonaceous oil is contacted with a solvent system that is a mixture of a major portion of a polar solvent having a dipole moment greater than about 1 debye and a minor portion of water to selectively separate the constituents of the carbonaceous oil into a heteroatom-depleted raffinate fraction and heteroatom-enriched extract fraction. The polar solvent and the water-in-solvent system are formulated at a ratio where the water is an antisolvent in an amount to inhibit solubility of heteroatom-containing compounds and the polar solvent in the raffinate, and to inhibit solubility of non-heteroatom-containing compounds in the extract. The ratio of the hydrocarbonaceous oil to the solvent system is such that a coefficient of separation is at least 50%.

  • Patent number: 5650063
    Abstract: Acidic halides, especially chlorides, are removed from a dry fluid stream by contact with dry particles of solid caustic. The solid caustic particles are preferably non-porous, and disposed as a fluidized bed. Salts deposit on the surface of the caustic and are physically removed, preferably by attrition, to regenerate the surface of the solid caustic. An dry, slightly alkaline salt can be the only product of neutralization. Salt coated beds of solid caustic can also be regenerated for reuse by attrition removal of salt deposits.

  • Patent number: 5595648
    Abstract: Acidic halides, especially chlorides, are removed from dry liquid hydrocarbon streams such as catalytic reformate by contact with large particles of low surface area solid caustic such as a bed of NaOH pellets. Effective neutralization is achieved in a bed which is essentially free of any aqueous phase. Salt formed by the neutralization reaction deposit as solids on the surface of the solid caustic. A process for producing a low chloride, dry reformate product is also disclosed.

  • Patent number: 4877515
    Abstract: Disclosed herein is a process for removing contaminating mercury from hydrocarbon streams, gas or liquid, wherein the stream is contacted with a molecular sieve pretreated with an alkali polysulfide. The pretreatment consists of saturating the sieve with an aqueous solution of the polysulfide and subsequently drying the saturated sieve under conditions calculated to dry but not decompose the polysulfide present.

  • Patent number: 4600502
    Abstract: A method for decreasing the foaming tendency of hydrocarbons, particularly lube basestocks, is disclosed. The method comprises passing the hydrocarbon through an adsorption zone having an adsorbent, preferably a basic adsorbent therein. In a preferred embodiment, the method comprises passing the hydrocarbon feedstock through a regenerable multi-bed adsorption zone. The foaming tendency of the hydrocarbon exiting from the bed in service is monitored. The flow to each particular bed in service is discontinued and the bed regenerated when the foaming tendency of the hydrocarbon exiting from each particular bed exceeds a predetermined value.
