FIELD: chemistry.
SUBSTANCE: hydrocarbon benzene fractions are obtained from synthesis-gas, containing H2, CO and CO2, by successive contacting of gas mixture in at least two reaction zones at pressure 40-100 atm and temperatures 340-420°C in first reaction zone and temperatures 320-460°C in second reaction zone, with bi-functional catalyst in first reaction zone, containing zeolite with structure ZSM-5 or ZSM-11 and metal oxide component, which consists of oxides of Zn, Cr and W, and monofunctional catalyst in second reaction zone, which contains zeolite with structure ZSM-5 or ZSM-11, with circulation of gas flow after reactor, characterised by the following: zerolite of monofunctional catalyst contains iron in amount from 0.3 to 1 wt %.
EFFECT: reduction of temperature and time of monofunctional zeolite catalyst regeneration.
