| abstract | 1473060 Alkylating isoparaffins TEXACO DEVELOPMENT CORP 20 Oct 1975 [4 Nov 1974 30 Dec 1974 (2)] 42949/75 Heading C5E [Also in Division B1] C 4 -C 6 isoparaffins are alkylated in the liquid phase with C 3 -C 5 mono-olefins to give gasoline blending stocks using a catalyst comprising HFSO 3 and H 2 SO 4 in the weight ratio 0À11/1 to 0À32/1, from 0 to 3% wt. water and 0 to 10% wt. of acid oils (formed by reaction of sulphuric acid with hydrocarbons present in the alkylation system) and the catalyst having a titratable acidity of 16À5 to 21 meq/gm. The isoparaffin may be iso-butane and the olefins propylene, butylene or a mixture thereof. The isoparaffin and olefin may be employed in a liquid volume ratio of 2 : 1 to 20 : 1 at 0‹ to 100‹ F. and 10- 150 p.s.i.g. using a reaction mixture comprising 40-60 vol. per cent hydrocarbon phase and 60-40 vol. per cent acid catalyst phase and an olefin volume space velocity of 0À1-1À0 hr.<SP>-1</SP> After reaction, the acid phase may be separated for recycle for re-use, a minor proportion being withdrawn for regeneration and replaced by fresh catalyst. The catalyst may be regenerated by hydrolysis of HFSO 3 to HF followed by reconversion to HFSO 3 by reaction with SO 3 and oxidation of H 2 SO 4 first to SO 2 then to SO 3 followed by reconversion to H 2 SO 4 . The resulting acids are then mixed in appropriate proportions. The examples describe the alkylation of isobutane with (i) butylene and (ii) a mixture of butylene and propylene. |
