An exothermic oxidation process wherein a rotating bed containing a variable oxidation state material is cycled through a succession of stages including an oxidative regeneration stage including a step wherein an oxidising fluid is passed through the bed, and a reaction stage wherein feedstock is passed through the bed, whereby said feedstock is oxidised to give products stream with the concurrent reduction of the convertible material to its lower oxidation state. The process can further include a stage wherein cooling fluid is passed through the bed.

Exothermic process

Process for the production of an aromatic amine by reacting an aromatic hydrocarbon with ammonia at a temperature of less than 500&deg; C. and a pressure of less than 10 bara in the presence of a catalyst comprising at least one metal selected from the group consisting of the transition elements, lanthanides and actinides, preferably in the presence of an oxidant.

Process for the production of aromatic amines

Catalytic process

A catalyst for decomposing an oxidizing agent, such as hypochlorite ions, in an effluent comprises an intimate mixture of at least one finely divided Group IIA oxide and finely divided nickel oxide, and/or hydrates thereof, supported on pieces of a non-porous substantially inert material. Some of the nickel may be replaced by cobalt. The Group IIA oxide forms 0.5 to 50% by weight of said intimate mixture. The nickel and Group IIA oxides may be applied by contacting the support with a solution of suitable salts, e.g. nitrates. Where the support is a Group IIA compound, e.g. magnesia, the Group IIA oxide may be incorporated into the intimate mixture by contacting the support with an acid solution of the nickel salt. In use the nickel oxide is oxidized to a higher oxidation state than NiO.

Catalyst for use in effluent treatment

In use the nickel oxide as oxidised to a higher oxidation state than NiO.

Effluent treatment

A method for the preparation of hydrocarbons and oxygenated hydrocarbons which comprises contacting a gaseous mixture of carbon monoxide, hydrogen and oxygen with a catalyst comprising a metal of Group VII or Group VIII of the Periodic Table, the amount of oxygen not exceeding 10% by volume based on the volume of hydrogen.
