A carbon monolith and a process of producing same, the process comprising the steps of: (i) mixing a carbonaceous precursor material with an alkali salt to form a first mixture; (ii) extruding the first mixture produced in step (i) into the shape of a monolith; and (iii) carbonizing the monolith produced in step (ii).

Provided are sorbents and associated methods and systems for removing mercury from process gases or fluid streams. The sorbents may include activated carbon and pyrite. The sorbents may optionally include one or more additives, such as a halide salt.

Provided is a hybrid process for producing high-purity para-xylene from a feedstock of aromatic hydrocarbon isomer fractions having 8 carbon atoms, in a liquid phase. The process includes a liquid chromatography separation step and a crystallization step of the para-xylene from the purified stream of para-xylene obtained at the separation step.

The subject invention pertains to proteins are purified by a mixed-mode chromatography system formed by attaching a ligand with cation exchange and hydrophobic 1,3-dioxoisoindolin-2-yl group functionalities to a large-pore support matrix, the only linkage between the ligand and the support matrix being a chain having a backbone of one, two, three, four, or five atoms between the hydrophobic group and the support matrix.

The invention provides a method of obtaining inorganic sorbents for extraction of lithium from lithium-containing natural and technological brines. The method consists of steps of obtaining six consecutive non-stoichiometric compound, wherein at the final step the sixth non-stoichiometric compound is obtained by converting the fifth non-stoichiometric compound into a hydrogen-form of inorganic ion-exchanger by treating the fifth non-stoichiometric compound with an acid solution. The method improves selectivity and exchangeability of sorbents to lithium based on manganese oxides, as well as chemical stability of the sorbents in cyclic operations.

Compacting expanded perlite fines in the presence of a small amount of binder (starch and/or clay) and water, followed by drying, produces particles with low density, good integrity, and surprisingly higher absorption by volume than non-compacted expanded perlite or non-swelling clay. Furthermore, addition of a small amount of clumping agent (e.g., guar gum) to the compacted granules results in a clumping litter with low density, good integrity and comparable clumping ability to traditional clay clumping litter.
