Isomerization of C/sub 4/-C/sub 6/ alkanes in the presence of hydrogen on catalysts promoted with fluorine and chlorine
We investigated the effect of hydrogen (molar ratio H/sub 2/:C/sub n/H/sub 2n+2/ and working pres-pressure) on the isomerization of C/sub 4/-C/sub 6/ alkanes on platinized and unplatinized chlorinated eta-Al/sub 2/O/sub 3/. The efficient isomerization of C/sub 4/-C/sub 5/ alkanes on a chlorinated alumina-platinum catalysts requires the presence of hydrogen. In the isomerization of alkanes in the gas phase (butane on a chlorinated catalyst of C/sub 5/-C/sub 6/ alkanes on a fluorinated catalyst) the changes in the degree of isomerization with the working pressure or the hydrogen:starting material ratio show common characteristics. The possible formation by C/sub 5/-C/sub 6/ alkanes of a liquid phase containing dissolved hydrogen in the pores of a chlorinated alumina-platinum catalysts determines the special character of the variation in the degree of isomerization of n-pentane and n-hexane with the working pressure and hydrogen:alkane ratio.
