Compacting expanded perlite fines in the presence of a small amount of binder (starch and/or clay) and water, followed by drying, produces particles with low density, good integrity, and surprisingly higher absorption by volume than non-compacted expanded perlite or non-swelling clay. Furthermore, addition of a small amount of clumping agent (e.g., guar gum) to the compacted granules results in a clumping litter with low density, good integrity and comparable clumping ability to traditional clay clumping litter.

A process for the preparation of a shaped MOF, the process comprising: providing a first reactant comprising at least one metal in ionic form and a second reactant comprising at least one organic ligand capable of associating with said metal in ionic form, and optionally a solvent; allowing the first and second reactants to react to form a MOF; and forming a shaped body directly from the mixture of step b) using an extruder or continuous kneader; wherein the initial ratio of the at least one metal in ionic form to the at least one organic ligand is controlled such that shaped bodies having a minimum defined crush strength are formed without the use of an external binder or lubricant.

The invention discloses a method for preparing a chlorine adsorption material for use in waste incineration and application of the chlorine adsorption material. The chlorine adsorption material adsorptive for chlorine-based substances during the waste incineration is prepared by mixing raw materials which include natural iron ores and quartz stones, and modifying the iron ores and the quartz stones with CaO through an ultrasonic impregnation method. The prepared chlorine adsorption material has a large pore size, a high porosity and a stable structure, and shows higher adsorption efficiency and adsorption capacity for the chlorine-based substances during the waste incineration. The use of the low-cost natural iron ores and quartz stones can reduce the cost in processing the chlorine-based substances, make great use of resources and facilitate environment protection.
