METHOD OF LOWER OLEFIN SYNTHESIS Russian patent published in 1996 - IPC

FIELD: chemical technology. SUBSTANCE: method involves the feeding parental raw with additions into furnace, mixture heating, cooling at outlet and the separation of the synthesized product for the end product and by-side components. To increase the volume of lower olefin synthesized by decrease of coke deposition amount and corrosion on the internal equipment walls the additions were dissolved in polar solvent and added to the hydrocarbon raw flow. Additions: salts of metals of periodic system group II-A, phosphorus-containing compounds and, optionally, - salts of metals of periodic system group I-A and sulfur-containing compounds. Polar solvent: water or alcohol. Additions were dissolved before their addition to the hydrocarbon raw flow. Method is used in oil-processing industry. EFFECT: improved method of synthesis. 29 cl, 4 tbl, 6 dwg
