标题:Synthesis of zeolites of small and uniform size having a high magnesium exchange capacity
发明人：KOSTINKO JOHN A
权利人:HUBER CORP J M
摘要:Zeolites of small and uniform size are formed having high magnesium exchange capacities. Zeolite A is disclosed having an average particle size less than 1.7 microns, a calcium carbonate exchange capacity of more than 230 mg calcium carbonate per gram zeolite and a magnesium exchange capacity of more than 140 mg magnesium carbonate per gram zeolite. This zeolite A is produced from a reaction mixture having a water to sodium oxide molar ratio of less than 35:1, and a sodium oxide to silica molar ratio of between 1:1 and 4:1, wherein the silica to alumina molar ratio is greater than 3:1 when the sodium oxide to silica molar ratio is less than 4:3 and the sodium oxide to alumina molar ratio is greater than 4:1 when the sodium oxide to silica molar ratio is greater than 4:3. Zeolite X is disclosed having an average particle size less than 2.2 microns, a calcium carbonate exchange capacity of more than 205 mg calcium carbonate per gram zeolite, and a magnesium exchange capacity of more than 130 mg magnesium carbonate per gram zeolite. This zeolite X is produced from a reaction mixture having a silicate alumina molar ratio greater than 5:1. A combination of zerolite A and zeolite X can be produced from the same reaction mixture.

摘要:Process for the preparation of an aqueous tar suspoemulsion by mixing a mixture including (a) a viscous tar composition formed from a tar, from inorganic solids and, optionally, from water, (b) water (W), (c) a surface-active agent (SA) exhibiting an HLB of at least 10 and, optionally, (d) a thickening water-soluble polymer (TWP) with a molecular mass of greater than 10,000, the relative amounts of constituents (W), (SA) and, optionally, (TWP) being such that the viscosity of the (W)+(SA)+optional (TWP) mixture is preferably equal to or greater than the viscosity of the said tar, and then optional dilution of the mixture obtained with water or with an aqueous acidic solution. The process is particularly advantageous when applied to to the residues, containing sulphuric acid, resulting from the synthesis of white oils from petroleum fractions. The present invention further relates to a method for fluidizing acidic tars/sludges including contacting the tar/sludge with sulfuric acid and a surfactant. Optionally, a carrier for the surfactant's incorporation into the tar/sludge can be utilized. This provides an effective process for cleaning sulfuric acid tars/sludges from containers/vessels such as transportation containers, pipes and storage tanks. Preferably, the process includes the additional step of regeneration of sulfuric acid from the fluidized tar/sludge.
