METHOD OF PREPARING STYRENE Russian patent published in 2001 - IPC

Abstract RU 2166494 C2

FIELD: petrochemistry. SUBSTANCE: ethyl benzene is subjected to catalytic dehydrogenation in multizone reactor at elevated temperature in the presence of steam, and reaction products are heated between zones due to indirect contact of dehydrogenation reaction products with reaction mixture of oxidation of noncondensed gas. EFFECT: more efficient process of dehydrogenation of ethyl benzene. 2 ex, 1 tbl
