  • Patent number: 11945728
    Abstract: A process for obtaining vanadium component in the form of vanadium oxide from gasifier slag is disclosed. The process comprises pulverizing the slag to obtain pulverized slag, which is blended with water and an alkali salt to obtain a slurry. The slurry is dried and then roasted in the presence of air to obtain a roasted slag. The roasted slag is leached to obtain a first filtrate comprising the vanadium component. The first filtrate is reacted with a magnesium salt to remove a silica component in the form of a precipitate. The silica free second filtrate is reacted with an ammonium salt to obtain ammonium metavanadate, which is further calcined to obtain the significant amount of vanadium pentoxide (V2O5).

  • Patent number: 11299681
    Abstract: The present disclosure relates to a process for reducing the amount of carbon disulphide (CS2) in a hydrocarbon feed containing C5-C8 fractions. The hydrocarbon feed is treated with an amine functionalized anion exchange resin (basic anion exchange resin) to obtain a mixture comprising a liquid fraction containing treated hydrocarbon and a solid mass containing an adduct of CS2 and the amine functionalized anion exchange resin. The so obtained liquid fraction containing the treated hydrocarbon is separated from the solid mass to obtain the hydrocarbon having CS2 content less than 2 ppm. The amine functionalized anion exchange resin can be regenerated from the solid mass.

  • Patent number: 10817607
    Abstract: Protecting a network device from malicious executable code embedded in a computer document. In one embodiment, a method may include detecting executable code embedded in a computer document stored on a network device. The method may also include detecting a potential hoax object in the computer document. The method may further include determining that the potential hoax object is a hoax object by determining that the potential hoax object includes a message enticing a user to enable execution of the executable code. The method may also include, in response to determining that the potential hoax object is a hoax object, concluding that the executable code is malicious and performing a security action on the network device that secures the network device from the malicious executable code.

  • Publication number: 20190161691
    Abstract: The present disclosure provides a process for reducing oxygenate content of hydrocarbon feed. The process comprises passing and heating the hydrocarbon feed over ion exchange resin resident in a reactor, maintained at a temperature in the range of 90 to 140° C. and a predetermined pressure, at a predetermined liquid hourly space velocity to obtain a heated intermediate fluid. The heated intermediate fluid is cooled to obtain a cooled intermediate fluid. The cooled intermediate fluid is mixed with water to obtain a mixture. The mixture is allowed to settle to obtain an aqueous phase and an organic phase. The aqueous phase is separated from the organic phase to obtain hydrocarbon feed with reduced oxygenate content. The process is simple and environment friendly, enabling removal of 70-90% of the oxygenate content from the hydrocarbon feed.
