The invention also relates to a method for producing same.

Disclosed is an activated carbon including pores formed on a surface thereof, in particular, the pores include ultra-micropores having a diameter that is equal to or less than about 1.0 nm.

The present invention relates to a process for the reduction of pitch in an aqueous medium generated in a papermaking or pulping process, comprising the following steps: a) providing an aqueous medium comprising pitch generated in a papermaking or pulping process; b) providing a ground calcium carbonate and/or a precipitated calcium carbonate; c) providing a hydrophobizing agent selected from an aliphatic carboxylic acid having between 5 and 24 carbon atoms; d) contacting the ground calcium carbonate and/or the precipitated calcium carbonate of step b) with the hydrophobizing agent of step c) for obtaining a hydrophobized ground calcium carbonate and/or a hydrophobized precipitated calcium carbonate; and e) contacting the aqueous medium provided in step a) with the hydrophobized ground calcium carbonate and/or the hydrophobized precipitated calcium carbonate obtained in step d), to the use of a hydrophobized ground calcium carbonate and/or a hydrophobized ground calcium carbonate for reducing the amount of pitch in an aqueous medium as well as to a hydrophobized ground calcium carbonate and/or a hydrophobized ground calcium carbonate and a composite of hydrophobized ground calcium carbonate and/or hydrophobized ground calcium carbonate and pitch.

The present invention relates to a filtering device (8) for removing substances from blood or a blood component, the filtering device (8) comprising: a housing having an inlet and an outlet, at first sorbent material coupled with at least a first ligand located within the housing, and a second sorbent material coupled with at least a second ligand located within the housing, wherein the first ligand is for removing free hemoglobin (fHb) and the second ligand is for removing microvesicles (MV) from the blood or blood component passing through the filtering device (8), from the inlet to the outlet, wherein the first and second ligand are different from each other, and wherein the first and second sorbent material are the same or are different from each other.

Guanidine-functionalized particles and methods of making and using such particles.

The invention relates to a method for the production of activated carbon, in particular particulate activated carbon, having an increased mesopore and/or macropore volume fraction preferably having an increased mesopore volume fraction.

A system and method of applied radial technology chromatography using a plurality of beads is disclosed, with each bead comprising one or more pores therein having a diameter of about 250 ? to about 5000 ?, and each bead having an average radius between about 100 ?m to about 250 ?m. Also disclosed are processes for selecting beads for use in a radial flow chromatography column, and for purifying an unclarified feed stream using a radial flow chromatography column.

Provided herein are methods of liquid column chromatography in which preparative chromatography is performed in-line with analytical chromatography. In particular aspects a monolithic preparative column is used to purify an analyte of interest from a mixture of other substances by applying the mixture to the column, reversing the flow through the column to elute the analyte, which is applied to an analytical column provided in-line with the preparative column. In other aspects, a single monolithic column is used to perform both the preparative chromatography and analytical chromatography steps in succession. In another aspect, a chromatography system is provided to perform preparative and analytical chromatography using a single monolithic column.

A composite filter aid may include at least one mineral associated with an antimicrobial metal compound, wherein the filter aid has a permeability ranging from 0.1 to 20 darcys. The antimicrobial metal compound can be chemically deposited on the mineral surface or bonded to mineral structure by binder or high temperature calcination.

The present description provides high working capacity adsorbents with low DBL bleed emission performance properties that allows the design of evaporative fuel emission control systems that are lower cost, simpler and more compact than those possible by prior art. Emission control canister systems comprising the adsorbent material demonstrate a relatively high gasoline working capacity, and low emissions.
