METHOD OF PRODUCING HYDROGEN SULPHIDE Russian patent published in 2011 - IPC C01B17/16 C22C35/00 

FIELD: chemistry.

SUBSTANCE: invention relates to a method of producing hydrogen sulphide from sulphur and hydrogen in a reactor. Sulphur and hydrogen react in a reactor at temperature between 400 and 550°C and pressure from over 9 to 20 bars. A reactor is used, and if needed and preferably - pipes, as well as reinforcement and elements and components of control-measurement and regulating apparatus in contact with aggressive medium, which are partly or completely made from material which is resistant to the corrosive action of the reaction medium, where the said material contains aluminium, or material which is coated with aluminium oxide or oxide on its surface which is in contact with the reaction mixture. The material contains aluminium in amount of 1-10 wt % and Cu, Co and/or Y in amount of 0-5 wt %. Synthesis is carried out in the presence of heterogeneous catalyst.

EFFECT: obtaining hydrogen sulphide on a industrial scale at high reaction pressure and temperature, which means with high efficiency, while ensuring longevity of the reaction equipment owing to reduced corrosive wear.
