The present invention relates to a process and apparatus for the removal of nitrous oxide from a feed gas stream using an adsorbent having a nitrogen diffusion parameter of 0.12 sec.sup.-1 or higher and a nitrous oxide capacity of 79 mmol/g/atm or higher at 30.degree. C.

Nitric oxides can be absorbed from gas mixtures containing nitric oxides (NO and NO.sub.2) and oxygen by absorption with aqueous solutions. According to the invention, the absorption is effected in bubble columns, superficial velocities of 2 to 30 cm/second being maintained. It is advantageous to connect several bubble columns in series such that the gas and absorption liquid pass in counter-current to one another. In this embodiment, considerably less counter-current stages are required to achi...

A housing has a vertical separation wall. The vertical separation wall forms a filling chamber on one side. The housing has a horizontal separation wall on the other side. The horizontal separation wall forms a cooling chamber. A quantity of a liquid in the filling chamber has an apertured horizontal plate at about the middle elevation of the filling chamber. A smaller end-user tank is provided on the plate. The level of liquid is sufficient to immerse the lower portion of a smaller end-user tan...

Nitrous oxide can be produced by reacting nitric oxide and carbon monoxide in the presence of a catalyst in an anhydrous system. The preferred catalyst is a mixture of PdCl.sub.2, CuCl.sub.2 and LiCl, which is dissolved in anhydrous methanol.

A process for producing nitrous oxide comprises reacting ammonia with nitric oxide and/or oxygen in the presence of a catalyst comprising a Group VIB metal oxide, to produce a reaction mixture comprising nitrous oxide, and optionally recovering the nitrous oxide from the effluent mixture.

Nitrous oxide having a high purity is produced by reacting urea, nitric acid and sulfuric acid at a temperature of 40.degree. through 100.degree. C., and isolating the resultant nitrous oxide from the reaction gas mixture, without any danger of, for example, explosion during the reaction and without using expensive catalysts and sulfamic acid.

A method for increasing the power output of an internal combustion engine is presented. The increase to the power output of the engine may be accomplished by injecting a pressurized oxygen enhancer, such as nitrous oxide, into the air intake of the internal combustion engine. A portion of the pressure derived from the injection is captured by a pressure port. The captured pressure is delivered to the fuel control device of the internal combustion engine such as the float bowl of a carburetor cau...

A reaction chamber in which nitrous oxide is decomposed, with liquid nitrous oxide delivered through an injector system to produce a swirling two-phase flow counter to the flow of the gases produced by decomposition, this counter flow being discharged from the injector system in a direction opposite to the flow of gases through and from the chamber.

This invention relates to a process for the conversion of nitrous oxide (N.sub.2 O) to nitrogen and oxygen using a supported catalyst comprising iron and, optionally, certain other metals and to a novel catalyst composition.

Ammonium nitrate is mixed, in a weight ratio of higher than 1:5, with a melt containing ammonium hydrogen sulfate and ammonium sulfate respectively present in the melt in a ratio of at least 4:1. The resultant mixture is subjected to thermal decomposition at 200-240 degrees C to produce nitrous oxide.
