METHOD FOR SIMULTANEOUS PRODUCTION OF AROMATIC HYDROCARBONS AND DIVINYL Russian patent published in 2013 - IPC C07C1/20 C07C15/00 C07C11/167 B01J29/40 B01J21/04 B01J21/08 B01J21/10 B01J23/06 

FIELD: chemistry.

SUBSTANCE: invention relates to petrochemical industry and specifically to catalytic processing of bioethanol into valuable petrochemical products, particularly high-molecular weight aromatic hydrocarbons. The technical result is achieved due to that catalytic conversion of ethanol or an ethanol-butanol mixture (3:1) is carried out at temperature of 400-420°C, volume rate of feeding low-molecular weight alcohols on liquid material of 2 h^-1 on a zeolite-containing catalyst of the following composition: ZnO - 1-2 wt %; γ-Al₂O₃ - 6-7 wt %; K₂O - 0.05-0.1 wt %; MgO - 2-3 wt %; SiO₂ - 2-3 wt %; HZSM-5 - the balance. The bioethanol conversion reaction is carried out in adiabatic continuous flow reactors. The bioethanol conversion products are hydrogenated in an autoclave-type reactor with volume of 250 cm³ at 250-300°C and 10 MPa.

EFFECT: high selectivity of the process of converting bioethanol and simultaneous production of divinyl in gas phase and aromatic hydrocarbons in liquid phase.
