Process for producing granular activated carbon
TLDR
Granular activated carbon is produced from a waste tire pyrolysis residue by kneading homogeneously the residue, a wooden carbonaceous material, and a carbonaceous binder under heat, extruding the resulting mixture by an extruder under certain heating conditions, and carbonizing and activating the extruded material as mentioned in this paper.Abstract:

Process for recovering carbon black and hydrocarbons from used tires
TL;DR: In this article, used tires are physically fragmented and the fragments are pyrolized at slightly sub-mospheric pressure in a reactor while process char is being recycled to increase heat transfer and avoid coke on heat transfer surfaces.
Patent
Method of producing activated carbon
TL;DR: In this paper, a fine-celled foam composition and a method of producing it is described, which is nontoxic, environmentally friendly, has improved absorption/adsorption and retention of liquids, is not as hard as prior art foams, does not include polymerization by-products detrimental to flower and plant life, and is a foamed mixture of a caustic silicate solution derived from the Caustic digestion of rice hull ash having diffused activated carbon particles from thermal pyrolysis of Rice hulls rather than from commercial sodium silicate solutions.
Patent
Recovery of commercially valuable products from scrap tires
TL;DR: In this paper, an improved process for producing carbon black by vacuum pyrolysis of used rubber tires is presented. But this process requires the use of a large number of used tires and requires a high temperature of up to 204°C.

Process for preparing spherical carbon material and spherical activated carbon
Hisatsugu Kaji,Kazuhiro Watanabe +1 more
TL;DR: In this article, a spherical carbon material or a spherical activated carbon is prepared from an admixture of pitch, amorphous carbon and a viscosity-controlling agent by the process comprising the step of heating and extruding the admixture into strings, cooling and cutting the string into fragments, introducing the fragments into hot water to obtain spherical particles of the mixture, removing the viscous agent from the spherical particles, infusibilizing the spherical particle and carbonizing the particle and further activating the carbonized spherical carbon particles.
Patent
Wood gasification apparatus
TL;DR: A wood gasification apparatus that includes an auger and housing assembly defining a decreasing volume spiral channel in which a particulate material is frictionally heated and vaporized is described in this paper.

Production of a char reinforcing agent from pyrolyzed scrap-rubber
TL;DR: In this paper, a RUBBER REINFORCING AGENT DERIVED from VULCANIZED SCRAP-RUBBER is CHARRED, TREATED FOR REMOVAL OF OIL, GROUND and then TREATED with ACID to REMOVE METAL COMPOUNDS.
Patent
Method of and apparatus for producing activated charcoal from waste tires
TL;DR: In this article, a method of producing activated charcoal comprising the steps of cutting waste tires into small pieces, subjecting these cut pieces of tires to high-temperature heating and burning in an atmosphere shut off from air to perfectly carbonize them, and then activating the charcoal thus produced to obtain activated charcoal, and an apparatus used in carrying out said method.
Patent
Adsorptive carbon and process of making the same
TL;DR: In this paper, an improvement in the concepts and processes of previously issued patents for the production of adsorptive charcoals or activated carbons was described, which relates to an improvement to an earlier patent for the same purpose.
Patent
