Abstract: Hydrogen sulfide is removed from coal gas for gas turbine power generation and recovered as elemental sulfur by contacting a coal gas formed by gasification of coal with an iron oxide catalyst, thereby removing hydrogen sulfide from the coal gas and obtaining a desulfurized coal gas; regenerating the iron oxide catalyst of lowered desulfurization activity, thereby obtaining a regeneration off-gas containing sulfur dioxide; converting a portion of said desulfurized coal gas to reducing gas containing hydrogen; reacting the hydrogen of the resulting reducing gas with the sulfur dioxide in a portion of said regeneration off-gas, thereby producing hydrogen sulfide; reacting the resulting hydrogen sulfide with the sulfur dioxide in the remaining portion of the regeneration off-gas in the presence of a catalyst, thereby producing a gas containing elemental sulfur, and recovering the elemental sulfur from the gas.

Abstract: Waste water issued from a wet type desulfurization apparatus and containing thionic acid ions is introduced into ion-exchange towers filled with weak-basic anion-exchange which has to effect anion exchange therein. The weak-basic anion-exchange resin which has adsorbed the thionic acid ions is desorbed by contacting an alkaline solution. The thionic acid ions included in the desorbing solution are decomposed by heating them in the presence of acid. A decomposed solution is issued out of the system after its neutralization.

Abstract: The pour plate that is inclined downwardly between the side conveyors of a U-shaped continuous molding tunnel is adjustable in width between the correspondingly adjustable side conveyors so as to selectively produce flat-top buns of foamed synthetic resin of a desired width within the range of adjustment. Interdigitating T-shaped fingers are transversely expandible to form the pour plate and have the gaps between the fingers closed by a cover sheet extending completely over the pour plate with sides being folded downwardly between the pour plate and side conveyors where they are attached to a bias that holds the cover sheet in stretched condition over the pour plate. The bottom cover web that travels with the foam may be folded or cut to the adjusted width of the pour plate. The interdigitated finger construction of the pour plate permits adjustment of the pour plate profile so as to correspond to the rise/time curve of the foam as it expands on our pour plate.

The oxidation, desulfurization and the separation of air are processes conducted continuously.

Abstract: Two opposed endless conveyor belts, together with side dams respectively mounted on the conveyor belts form a molding tunnel for producing a continuous sheet of foamed and cured resin. A cover sheet, usually of paper, is provided between the molding surfaces of the side dams and conveyors and the product being formed. The side dams are movable toward and away from an abutting surface of the conveyor opposite to the one that they are mounted on so as to clamp the paper therebetween and prevent leakage of foam. A mechanism, particularly a spring bias and cam track, is provided to release the paper clamping pressure to permit the foaming resin briefly to permit the expanding resin to move the paper into conformity with the molding tunnel. The points along the length of the molding tunnel wherein this release occurs are adjustable as desired.
