Abstract: The present invention is directed to an activated carbon made from macadamia nuts. The macadamia nuts each comprise an outer husk, a shell and a kernel. The shell is used as a material of the activated carbon. The shell is separated from the husk and the kernel and subjected to carbonization and activation processes to obtain the activated carbon.

Abstract: A process for producing granular activated carbon using wood as a carbon source is described. The process comprises pulverizing wood to produce a wood powder in a fine granular form, drying the wood powder to produce a dry wood powder having a water content of not more than 10% by weight, adding at least one of coal tar and ground pitch to the dry wood powder in an amount of from 5 to 20% by weight based on the total amount of the wood powder and the binder to prepare a raw material, placing the raw material in a pellet mill, extruding the raw material under such temperature and pressure conditions that it is plasticized, and simultaneously cutting it to produce pellets, carbonizing the pellets by heating, and activating the carbonized pellets in a high temperature steam atmosphere. This process makes it possible to efficiently produce activated carbon of high mechanical and adsorption performance.

Abstract: The instant invention is directed to a process for the continuous manufacturing of carbon molecular sieves having average effective pore diameters of from 2 to 15 Angstroms which comprises continuously feeding a charred naturally occurring substrate to a means for heating said substrate and heating said substrate under non-activation conditions, without the use of an externally added pore blocking substance, at a temperature range of about 900.degree. F. (482.degree. C.) to 2000.degree. F. (1093.degree. C.) for a time period of about 5 to 90 minutes.The instant invention is also directed to a carbon molecular sieve, useful for separating gas or liquid mixtures containing components of at least two different molecular diameters, molecular weights or molecular shapes which has the following physical characteristics:(a) an apparent density of from 0.60 to 0.70 g/cc,(b) an oxygen diffusivity (.times.10.sup.-8) of from 500 to 900 cm.sup.2 /sec,(c) an oxygen/nitrogen selectivity ratio of from 5.0 to 8.

Abstract: An improved solid carbon reductant comprising partially calcined carbonaceous materials such as petroleum coke, containing relatively low amounts of residual hydrocarbons and a relatively high surface area and thus increased activity as compared to known reductants is provided. This improved reductant is produced by a method comprising heating the carbonaceous material in an oxidizing atmosphere to a temperature of from about 650.degree. C. to about 950.degree. C., preferably from about 800.degree. C. to about 875.degree. C., and most preferably at a temperature about 850.degree. C. In addition, according to the present invention improved chlorination processes are provided using these reductants which result in reduced levels of chlorinated hydrocarbon (C.sub.x Cl.sub.y) production due to reduced residual hydrocarbons. In a preferred embodiment anhydrous aluminum chloride is produced by chlorination of aluminum hexahydrate using the improved reductant.

Abstract: Carbonaceous pyropolymers possessing recurring units containing at least carbon and hydrogen atoms composited on a solid support may be prepared in a solid state process. The process is effected by treating a high surface area solid support such as an inorganic oxide as exemplified by alumina with an organic monomer which is capable of being polymerized by thermal, ionic, or free radical polymerization methods. The monomer is polymerized on the surface of the support under polymerization conditions and thereafter the polymer-coated support is subjected to pyrolysis at temperatures ranging from about 600.degree. to about 1200.degree. C. to form a carbonaceous pyropolymer. If so desired, this composite may then be subjected to the action of a dissolving agent under conditions which will dissolve or leach out the solid support, thus leaving a carbonaceous pyropolymer possessing recurring units containing at least carbon and hydrogen atoms.
