METHOD OF IMPROVING AROMATISATION CATALYST Russian patent published in 2013 - IPC C07C15/02 C07C15/04 C07C5/393 C10G35/95 C10G35/24 B01J29/62 B01J27/08 

FIELD: chemistry.

SUBSTANCE: invention relates to versions of method of hydrocarbon aromatisation. One of method versions includes introduction of nitrogenate, oxygenate or both into hydrocarbon flow with obtaining improved hydrocarbon flow, containing from approximately 2 ppm to 10 ppm of nitrogenate, oxygenate or both, interaction of improved hydrocarbon flow with catalyst of aromatisation in reaction zone, where catalyst contains non-acidic zeolite carrier, group VIII metal and one or more halogenides; removal of output flow, which contains aromatic hydrocarbons, where nitrogenate refers to ammonia or any chemical compound, which forms ammonia in conditions of catalytic reaction, and where oxygenate refers to water or any chemical compound which forms water in conditions of catalytic reaction.

EFFECT: application of claimed invention makes it possible to preserve and increase aromatisation catalyst productivity.
