Title: Means and method for controlling the strength of acid in an alkylation unit
IPC: B01J19/00
Filed: 1972-08-02
Abstract: The strength of acid in an alkylation unit is controlled by a system using a signal corresponding to the anticipated demand on the acid by the reaction of olefin and isoparaffin in the presence of the acid. The reaction weakens the acid so that it is necessary to replace some of the weakened acid with fresh acid to maintain a desired acid strength. The control system includes apparatus sampling the olefin and isoparaffin entering the alkylation unit which provides a signal corresponding to the percent volume of acid degrading constituents formed during alkylation. A water analyzer samples the olefin and isoparaffin and provides a signal corresponding to their water content. Signals corresponding to sensed flow rates of fresh and discharged acid entering and leaving, respectively, the alkylation unit and of the olefin and isoparaffin are provided by sensors. A control circuit using analog computers develop the control signal in accordance with the signals from the sensors, the volume signal and the signal from the analyzer and equations hereinafter disclosed. The control signal is applied to a flow recorder controller which controls the flow rate of the fresh acid entering the alkylation unit so as to maintain the desired acid strength.

Title: Process for making flavorless food extenders derived from peanuts, and a method of recovering peanut oil
IPC: A23L25/00
Filed: 1976-01-24
Abstract: A process for making fat-free flavorless peanut flakes having utility as a high protein food extender by forming an aqueous mix of finely ground raw peanuts, or raw peanuts from which a part of the oil has been removed by mechanical pressure, drying the mix into a thin stratum, and extracting the oil with a solvent such as hexane. The process includes making full-fat, or partially defatted, flavorless shelf-stable peanut flakes or flour by the removal of volatile flavor compounds from an aqueous emulsion-suspension of finely ground raw peanuts, heating the emulsion-suspension to high temperatures, and dehydrating the cooked emulsion-suspension. Antioxidants and metal complexing agents may be added to the emulsion-suspension prior to dehydration. The aqueous suspension-emulsion is useful for preparation of milk-like beverages after removal of volatile flavor compounds, before or after dehydration. Defatted, partially defatted, and full-fat peanut flakes are useful in formulations for sandwich spreads, confections, imitation meat-type items, breakfast cereals and in peanut butter to modify consistency and reduce stickiness in the mouth, and as extenders for meat poultry, and fish.

Title: Hydrogenation catalyst and process for preparing same
IPC: B01J23/889
Filed: 1976-02-13
Abstract: A hydrogenation catalyst containing cobalt, manganese and copper in the form of their oxides and alkali metal oxide and silicon dioxide. A weight ratio of cobalt to maganese is 25:1 to 1:1, and the copper content is 0.01 to 2% by weight based on a total weight of the catalyst. The catalyst is prepared by adding an excess of an aqueous solution of a hydroxide, bicarbonate or carbonate of an alkali metal to an aqueous solution of water-soluble cobalt salts, manganese-(II) salts and copper salts to form a precipitate. Thereafter an aqueous solution of an alkali metal silicate or SiO2 sol is added to the precipitate which is filtered off and washed with water to remove excess alkali metal hydroxide, bicarbonate or carbonate. The precipitate is then dried and calcined to form the catalyst.

Title: Phosphate-free concentrated particulate heavy duty laundry detergent
IPC: C11D3/10
Filed: 1977-11-30
Abstract: A free flowing phosphate-free particulate heavy duty laundry detergent is comprised of particles of a mixture of sodium carbonate and sodium bicarbonate having nonionic detergent in the interior and on the surface thereof, to which is adhered a coating of smaller particles of ion exchanging zeolite.
