摘要： A stable, nonhygroscopic potassium monopersulfate composition comprising KHSO.sub.5, KHSO.sub.4 and K.sub.2 SO.sub.4 having a composition represented by a point within the closed curve of FGHIF of FIG. 1.A process for preparing a stable, nonhygroscopic potassium monopersulfate composition having the following formula:(KHSO.sub.5).sub.x.(KHSO.sub.4).sub.y.(K.sub.2 SO.sub.4).sub.zwhere x+y+z=1 and x=0.48-0.64, y=0.15-0.37, and z=0.15-0.37 includes providing Caro's acid having a molar ratio of H.sub.2 SO.sub.5 /H.sub.2 SO.sub.4 of 1.6 or more and a water content of 40 to 65 weight percent, partially neutralizing the Caro's acid with a basic potassium compound to form a reaction mixture having a potassium to sulfur ratio (K/S) of 1.15 to 1.25 and a molar ratio of KHSO.sub.5 /(KHSO.sub.4 +K.sub.2 SO.sub.4) greater than 1.0, adding the reaction mixture to a solution having a molar ratio of KHSO.sub.5 /(KHSO.sub.4 +K.sub.2 SO.sub.4) greater than 2.5 to produce a final mixture having a molar ratio of KHSO.sub.5 /(KHSO.sub.4 +K.sub.2 SO.sub.4) of between 1.3 and 7.3, concentrating the final mixture in a vacuum crystallizer to produce a slurry, separating the slurry into a wet cake and a mother liquor, and drying the wet cake.An alternative process for preparing the triple salts includes using a triple salt of Caro's acid as the starting material, removing K.sub.2 SO.sub.4 from the starting material to produce a filtrate, neutralizing the filtrate, adding the neutralized filtrate to a KHSO.sub.5 -rich solution to produce a final mixture, crystallizing the mixture to produce a slurry, separating a wet cake from the slurry, and drying the wet cake.

摘要： An environmentally safe and compatible filter and dehydrator apparatus for dehydrating and filtering impurities from fuel materials having a filter housing, a filter element composed of non-metallic, environmentally safe material and a water sensor used to detect the presence of water and generate a signal in response thereto to automatically engage a pump to remove a quantity of separated water from the filter housing, in the absence of allowing air to enter the filter housing. While processing fuel through the filter housing, a natural fuel/water contact forms within a lower portion of the filter housing. As fuel material is filtered and the fuel/water contact rises within the filter housing, the fuel/water contact approaches the water sensor. When the water sensing means detects the presence of water, the water sensor generates a signal to engage a pump to remove a quantity of separated water from a lower opening in the lower portion of the filter housing. The separated water is automatically removed in the absence of allowing air to enter the filter housing and the fuel/water contact is kept at a minimum elevation within the filter housing and away from the filter element.

摘要： Catalytic activity of a platinum group metal catalyst used in catalyzing the hydrogenation of a working solution of an alkylanthraquinone in a water-immiscible solvent in the manufacture of hydrogen peroxide, said catalyst having become at least partially inactivated, is regenerated by a process comprising contacting the catalyst in the presence of the working solution and in the absence of hydrogen with an oxidizing agent selected from the group consisting of an oxygen-containing gas and hydrogen peroxide.When the process of the invention is made an integral part of the cyclic anthraquinone process for producing hydrogen peroxide, there results an improvement in the latter process whereby the activity of the catalyst can be maintained at a high level.
