Abstract: 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.

Abstract: A process for treating a substrate, e.g., lignocellulosic pulp or cellulosic pulps, with a mixed peracid solution comprising percarboxylic acid and Caro's acid which results in a higher conversion rate of the active oxygen in the hydrogen peroxide in order to provide an inexpensive and effective delignification and/or bleaching solution and the process for making the mixed peracid solution.

Abstract: An improved process for preparing alkanoyloxyacetyloxybenzenesulfonate salts in which phenyl esters of alkanoyloxyacetic acids (alkanoyloxyacetyloxybenzenes) are sulfonated to yield novel alkanoyloxyacetyloxybenzenesulfonic acids which, on neutralization, yield the corresponding alkanoyloxyacetyloxybenzenesulfonate salts.

Abstract: 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.
