  • Patent number: 9453130
    Abstract: An integrated scrap tire pyrolysis plant can be built to process scrap tires. The recovered carbon black can be used in rubber and plastic industries. Oil and gas from the pyrolysis process can further be used in the production of virgin carbon black. Natural rubber is a sustainable feedstock for the manufacture of tires, making the manufacture of virgin carbon black partially sustainable. A very low PAH carbon black can be produced by limiting the exit temperature of carbon black and tail gas prior to leaving the reaction chamber.

  • Patent number: 9440189
    Abstract: Processes, methods, system and uses in relation to chemical sequestration of carbon dioxide from a carbon dioxide containing gas by carbonation of an alkaline earth metal containing material. The carbon dioxide containing gas is contacted with an aqueous slurry in a carbonation unit for carbonation of at least a portion of the alkaline earth metal to produce a carbon dioxide depleted gas and a carbonate loaded slurry which is substantially exempt of precipitated alkaline earth. metal carbonates. The carbonate loaded slurry is then separated into an aqueous phase and a solid phase; and the aqueous phase is supplied to a precipitation unit for precipitating alkaline earth metal carbonates. The carbonation stage may be performed at a carbonation temperature between about 10° C. and about 40° C. and a carbonation pressure between about 1 bar and about 20 bars. The solid phase may be recycled to the carbonation stage.

  • Patent number: 9440854
    Abstract: A composition and a method for producing mesoporous carbon materials with a chiral or achiral organization. In the method, a polymerizable inorganic monomer is reacted in the presence of nanocrystalline cellulose to give a material of inorganic solid with cellulose nanocrystallites organized in a chiral nematic organization. The cellulose can be carbonized through thermal treatment under inert atmosphere (e.g., nitrogen or argon) and the silica may subsequently be removed using aqueous solutions of sodium hydroxide (NaOH) or hydrogen fluoride (HF) to give the stable mesoporous carbon materials that retain the chiral nematic structure of the cellulose. These materials may be obtained as free-standing films with very high surface area. Through control of the reaction conditions the pore-size distribution may be varied from predominantly microporous to predominantly mesoporous materials.

  • Patent number: 9381493
    Abstract: A novel carbon absorption material is described which is formed from anaerobic digestate. The material has a hollow tubular structure and is particularly advantageous in converting hydrogen sulfide in biogas and in absorbing the converted sulfur and sulfur compounds from biogas into its structure. The material after use as a hydrogen sulfide absorbent has value as a horticultural or agricultural product or as a sulfur impregnated activated carbon. The process for producing this novel carbon absorption material is described. In an embodiment, the process described uses in particular, a humidified inert gas over a temperature range of between about 500° C. to 900° C. to convert anaerobic digestate to an active carbon absorbent. The thermal treatment is relatively mild and retains the fibrous structure of the source material while removing cellulosic and hemicellulosic components from the anaerobic digestate.

  • Patent number: 9379385
    Abstract: (Problem) A porous carbon material having excellent graphite crystallinity, good carrier mobility and proper porosity, a porous carbon material having edges of carbon hexagonal planes located on outer surfaces of particle and structure, and flaky graphite being similar to graphene are produced. (Means to Solve) By subjecting a carbon material, in which a closed-pore-ratio and an amount of remaining hydrogen in the material are set to be within a proper range, to hot isostatic pressing treatment, a vapor phase growth reaction of graphite is generated in closed pores as nuclei using hydrogen and hydrocarbon generated from the carbon material, thereby producing a large amount of targeted porous carbon material at low cost. Flaky graphite being similar to graphene is produced by applying physical impact to the obtained porous carbon material or by generating a graphite intercalation compound using the porous carbon material as a host and then quickly heating the compound.
