Abstract: Disclosed is a process for the concurrent production of hydrogen and sulphur from a H2S-containing gas stream, with zero emissions. The method comprises the thermal oxidative cracking of H2S so as to form H2 and S2. Preferably, the oxidation is conducted using oxygen-enriched air, preferably pure oxygen. The ratio H2S/O2 in the feedstock is higher than 2:1, preferably in the range of 3:1-5: 1.

Abstract: The present invention relates to a method for hydrogen production and to a method of hydrogen and/or carbon dioxide production from syngas. The method comprises the steps of: (i) providing a gas stream comprising hydrogen and carbon monoxide, (ii) separating at least part of hydrogen from the stream yielding a hydrogen-depleted stream, (iii) subjecting the hydrogen- depleted stream to a water-gas shift reaction, and (iv) separating hydrogen from the stream resulting from step (iii). The method according to the invention improves the conversion of carbon monoxide in the water gas shift reaction and allows to increase the hydrogen production by 10-15% and to increase the overall energy efficiency of the system by 5-7%. The invention further relates to a plant for hydrogen and/or carbon dioxide production suitable for the method of the invention.

Abstract: Disclosed is a process for the production of a syngas mixture by catalytic partial oxidation. The syngas mixture is suitable as an intermediate in the production of hydrogen. According to the invention, the syngas is cooled, prior to a water gas shift reaction, with liquid water. This has the advantage of avoiding the problem of metal dusting, and it presents a gas mixture comprising water vapor that is particularly suitable for a water gas shift reaction in the production of hydrogen.

Abstract: An improved process for the recovery of ammonia and sulphur dioxide from a by-product mixture containing an ammonium salt of sulphuric acid obtained as a by-product in the preparation of epsilon -caprolactam or cyclohexanone oxime. The by-product mixture is reacted, in finely divided form and at a temperature of from 700 DEG to 950 DEG C., with gases obtained from the combustion of a fuel in a controlled amount of oxygen, and ammonia and sulphur dioxide are thereafter separated from the resulting reaction mixture. The amount of oxygen is controlled to be less than the theoretical additional amount that would be required to convert the nitrogen, sulphur, hydrogen and carbon contained in the by-product mixture and fuel into, respectively, N2, SO2, H2O and CO2.
