The present invention relates to a specific continuous process for preparing a zeolitic material having a framework structure type selected from the group consisting of MFI, MEL, IMF, SVY, FER, SVR, and intergrowth structures of two or more thereof, preferably an MFI- and/or MEL-type framework structure, comprising Si, Ti, and O, and to a zeolitic material as obtainable and/or obtained according to said process. Further, the present invention relates to a process for preparing a molding, and to a molding obtainable and/or obtained according to said process. Yet further, the present invention relates to a use of said zeolitic material and molding.

The present invention concerns a zeolitic adsorbent agglomerate comprising at least one zeolite of faujasite type comprising sodium and/or lithium and/or calcium, and/or barium and/or potassium, of porosity between 25% and 45%, and having a standard deviation σ of crystal size distribution in said agglomerate of less than 0.30 μm. The invention also concerns the use of the zeolitic adsorbent agglomerate to separate hydrocarbon mixtures, and the process to separate hydrocarbon mixtures using said zeolitic adsorbent agglomerate.

A device and method for preparing in-situ molded biochar with high specific surface area. Crushed and mixed biomass and modifier are fed into a hot pressing and pyrolysis device, and hot-pressing molding and pyrolysis carbonization are completed synchronously, which solves the problem of multiple steps and complicated equipment in the existing preparation process for molded biochar material. In-situ bonding molding is realized by adhesion, bridging, cross-linking and mechanical interlocking functions of low-temperature molten & softened lignin and pyrolytic tar. No additional cross-linking agent is needed in this process, so the production cost is low. Covering and suffocating actions of trace flame retardant modifier are utilized to reduce the temperature of biomass pyrolysis carbonization, inhibit excessive ablation and accelerate polycondensation reaction, thus to improve the specific surface area and yield of a product, and improve the cost performance of the product.

The sodium ferrite particle powder according to the present invention is characterized in that at least one metal or more selected from the metal group consisting of silicon, aluminum, titanium, manganese, cobalt, nickel, magnesium, copper and zinc is contained in an amount of 0.05 to 20% by weight in terms of the oxide, and the molar ratio of Na/Fe is 0.75 to 1.25.

Smoking article include a smokable material and an activated carbon particle downstream of the smokable material. The activated carbon particle is produced from a whole seed. The activated carbon particle has a length, width and height. At least two of the length width and height are independently in a range from about 1 mm to about 7.5 mm. The particles can be spheroids, in which case the length, width and height would be the same or similar.

A process for recovery of lithium ions from a lithium-bearing brine, the process comprising: contacting the lithium-bearing brine with a lithium ion adsorbent based on orthosilicate. The lithium ion adsorbent is a de-lithiated form of: Li.sub.2X.sub.1-y-zY.sub.yZ.sub.zSiO.sub.4, where y and z together=0 to 1 and X, Y and Z are each Fe, Mg, Ca, Ni, Mn, Co, Zn, Cu, Ti, V, Sr or Zr.

Described herein is a an adsorbent and/or absorbent composition, a method of preparing the adsorbent and/or absorbent composition, and method of treating a fluid stream with the adsorbent and/or absorbent composition. Alumina and carbon are combined with polyacrylamide (PAM) powder and water in preferred proportions and impregnates such as Group 1A metal hydroxides. Group 7A salts of Group 1A metals optionally can be added.

A bleaching clay product, a method of producing and a method of decolorizing an oil are disclosed. The bleaching clay product comprises attapulgite that has been thermally activated. The bleaching clay product may have a permeability in oil in the range of 0.04-3 darcy and may have a surface area of 45-140 m.sup.2/g. The method of producing such bleaching clay product may comprise thermally activating a material that includes attapulgite by heating the material at a temperature in the range of 300 to 900° C. The method of decolorizing may include contacting for a contact time an oil with the bleaching clay product that comprises attapulgite that has been thermally activated, and separating the bleaching clay product from the oil to recover a decolorized oil that has a lower red color than the oil had prior to the contacting.
