FIELD: chemistry.
SUBSTANCE: bifunctional cobalt-containing zeolite catalyst for synthesis of aromatic hydrocarbons (mixture of benzene, toluene, xylols and ethyl benzene) from synthetic gas contains a structural promoter - magnesium (II) oxide and an energy promoter - titanium oxide or hafnium oxide, in which the zeolite component used is zeolite ZVM in Ga form with molar ratio SiO2/Al2O3=30, and ratio of components in pts. wt: cobalt 50-150, magnesium (II) oxide 2-8, hafnium oxide or titanium oxide 2-5, zeolite (Ga form) 100-300, a method of preparing said catalyst and a method for synthesis of aromatic hydrocarbons from synthetic gas using said catalyst. The catalyst is characterised by low formation carbon dioxide - main by-product whose output is over 100 g/m3, and optimum ratio of components reaches 50 g/m3. Disclosed catalyst is characterised by high stability and enables synthesis of aromatic hydrocarbons without loss of selectivity for desired synthesis products for a long period of time (over 30 hours).
EFFECT: possibility of selective synthesis of aromatic hydrocarbons with output of desired products.
