One aspect of the present invention relates to an adsorption filter containing an activated carbon and a fibrous binder. The adsorption filter has a density of 0.400 g/ml or more, and a pore volume at a pore diameter of 1 to 20 μm is 0.60 ml/g or less as measured by mercury intrusion porosimetry.

Activated carbon, e.g., from waste tires, modified by bimetallic Fe and Ce nanoparticles can provide high surface area and active sites for enhanced dye adsorption. Such nanocomposites can offer magnetic removal from aqueous solutions containing, e.g., Methylene Blue or Rhodamine B. Adsorption equilibrium data fit well to the Langmuir isotherm model, with an adsorption capacity was 324.6 mg/g. Rhodamine B adsorption by such activated carbon-Fe—Ce magnetic adsorbents has an endothermic character and pseudo-second-order kinetics. In ethanol solution, rhodamine B was desorbed at high efficiency and such materials, which could be recycled up to 5 cycles. Such magnetic nanocomposites are adsorbents for treating dyes such as rhodamine B in wastewater, even in large scale adsorption systems. Polyamides can be grafted to such nanocomposites.

Solid absorbent compositions and methods for the removal of mercaptan sulfur compounds from hydrocarbon streams are provided. The compositions may include porous granulated activated carbon particles with internal pore surfaces containing bound trinuclear basic iron (III) acetate complex containing the [Fe.sub.3(.sup.3-O)] core structure.

High surface area magnesium carbonate structures formed from a calcined slurry of magnesium carbonate powder and a binder and method for their use to adsorb aqueous phosphate and ammonia for recovery and repurposing as a fertilizer are disclosed. A binder is utilized to aid in the formation of useful structures. The binder significantly increase porosity and the available surface area for adsorption.

A m-xylene adsorbent contains 94 to 99.9 wt % of a Y molecular sieve and 0.1 to 6 wt % of a matrix. The Y molecular sieve consists of a non-crystal-transformed Y molecular sieve and a Y molecular sieve produced by a crystal transformation. The non-crystal-transformed Y molecular sieve is a mesoporous nano Y molecular sieve, which has a crystalline grain size of 20 to 450 nanometers, contains two types of mesoporous pores, and respectively has most probable pore diameters of 5 to 20 nanometers and 25 to 50 nanometers. The adsorbent is used for adsorptive separation of m-xylene from mixed C8 aromatic hydrocarbons.
