Abstract
Abstract A system for delivering a catalyst into a forced draft entry port of a chemical reaction chamber, such as a fossil-fuel combustion chamber, includes a container having an aqueous solution of the catalyst. A suction line extends from an air space above the solution to the entry port. An intake line at atmospheric pressure enters the container and has an end submerged below the surface of the aqueous solution, the submerged end having a float for maintaining the end at a predetermined distance below the surface and thereby establishing a predetermined back pressure. A layer of oil floats on top of the aqueous solution and may contain a second dissolved catalyst. The air from the intake line bubbles up through the aqueous solution and the oil layer absorbing minute quantities of the catalysts which are carried by the air into the reaction chamber. Rhenium and manganese catalysts improve the efficiency of fossil-fuel combustion such as that of the home oil burner and the automotive engine. Ethylene glycol serves as a surfactant and as an antifreeze agent. Group-1 chlorides in solution inhibit precipitation of the catalyst by the surfactant.
