A structure for adsorbing contaminants from cooking oil comprises: an outer shell comprised of a filter material; and an adsorbing mixture comprising rice hull ash blended with a reinforcing binder, wherein the adsorbing mixture is in the form of particles having a particle size from about 0.30 millimeters (300 microns) to about 1.40 millimeters (1400 microns), with an average particle size of about 0.60 millimeters (600 microns) to about 0.70 millimeters (700 microns). The adsorbing mixture is enclosed by the outer shell, such that, in use, cooking oil with the contaminants passes through the outer shell, contacts the adsorbing mixture within the outer shell, and then again passes through the outer shell with substantially fewer contaminants.

The present invention generally relates to binderless zeolitic adsorbents and methods for making the binderless adsorbents. More particularly, the invention relates to FAU type binderless zeolitic adsorbents and methods for making the FAU type binderless adsorbents. The FAU type binderless adsorbents may be used for xylene separation and purification in selective adsorptive separation processes using binderless zeolitic adsorbents.

The present disclosure is directed to an immobilized media device and methods for making an immobilized media device. The present disclosure is also directed to methods for the separation of components of a media comprising filtering the media through an immobilized media device.

A method of making clumping deodorizer granules can include applying a clumping agent to a particles containing activated carbon to at least partially coat an outer surface of the particles with a distinct layer comprising the clumping agent. Clumping deodorizer granules can include particles containing activated carbon, and an outer surface of each of the particles is at least partially coated with a distinct layer containing a clumping agent. A method of reducing malodor from animal waste can include adding clumping deodorizer granules to a pet litter in a litter box, the clumping deodorizer granules including particles containing activated carbon, and an outer surface of each of the particles is at least partially coated with a distinct layer containing a clumping agent.

Disclosed is a porous ceramic heating element composition and a ceramic heating structure made of the composition, and the composition includes: a mixture including a ceramic mixed powder, which is formed by mixing at least one of an aluminum nitride and a silicon nitride with a silicon carbide powder, and a silicon-based metal powder which is mixed with the ceramic mixed powder; a pore agent, wherein 0.5 parts by weight to 5 parts by weight of the pore agent is mixed with 100 parts by weight of the mixture; and a binder which is mixed with the mixture and maintains the bonding between the ceramic mixed powder and the metal powder. 20 parts by weight to 30 parts by weight of the binder is included in 100 parts by weight of the mixture.

Processes for removing arsenic compounds from a feed stream using an adsorbent in disclosed. The process includes contacting a feed stream comprising at least arsenic and sulfur compounds with an adsorbent comprising an low-crystallinity manganese oxide, at least one halide and a binder, to provide a treated effluent substantially free of the arsenic and sulfur compounds.

A method of removing organic carbon and other contaminants from a water stream. The method comprises screening large solids from the stream. Pre-oxidation chemicals may then be added. A coagulant is fed into the stream. An activated carbon, preferably formed from lignite, is added by pumping a highly concentrated activated carbon slurry into the stream. The stream, including the activated carbon and coagulant, next flows into a clarifier, where the coagulant will flocculate and enmesh the activated carbon. The activated carbon adsorbs organic carbon and other contaminants, including bacteria, pharmacological agents, and hydrocarbons, as the stream flows through the clarifier. Eventually, the flocculate will agglomerate and settle out in the clarifier, where it, the enmeshed carbon, and the contaminants they contain may be removed. The stream's organic carbon content exiting the clarifier will be much reduced. Accordingly, less primary oxidizing agent will be needed to treat any remaining organic carbon.
