Title (EN) METHOD OF SEPARATION OF ISOBUTYLENE FROM C4 HYDROCARBON FRACTION
(FR) PROCEDE DE SEPARATION DE L"ISOBUTYLENE D"UNE FRACTION D"HYDROCARBURE EN C4
Abstract: front page image
(EN)A method of separation of isobutylene from C4 hydrocarbon fraction comprising a stage of treatment of the C4 hydrocarbon fraction with water under the conditions of counterflow contacting at a speed of water flow of 5 to 30 m/h and at a speed of motion of the C4 hydrocarbon fraction in the layer of the catalyst of 0.001 to 0.020 m/sec. at a temperature of 70 to 110 C and under a pressure of 16 to 23 atm. in the presence of a formed ionic catalyst and a stage of dehydration of the thus produced tertiary butanol into isobutylene at a temperature of 80 to 110 C and under a pressure of 3 atm. in the presence of the said catalyst.
(FR)Un procede de separation de l"isobutylene d"une fraction d"hydrocarbure en C4 consiste a traiter la fraction d"hydrocarbure en C4 avec de l"eau par contact a contre-courant, ou la vitesse de l"ecoulement de l"eau est de 5 a 30 m/h et ou la vitesse du deplacement de la fraction d"hydrocarbure en C4 dans la couche du catalyseur est comprise entre 0,001 et 0,020 m/sec a une temperature se situant entre 70 et 110 C et sous une pression de 16 a 23 atm. en presence du catalyseur ionique forme et le procede comprend la deshydratation du butanol tertiaire ainsi produit en isobuthylene a une temperature se situant entre 80 et 100 C et sous une pression de 3 atm. en presence dudit catalyseur.
