ABSTRACT:
In one embodiment, C.sub.4 -C.sub.10 alkanes and/or C.sub.5 -C.sub.10 cycloalkanes are isomerized in the presence of a catalyst which has been prepared by heating AlCl.sub.3, at least one aluminum sulfate-containing support material and at least one chlorinated hydrocarbon (preferably CCl.sub.4) at about 40.degree.-90.degree. C., followed by separating the formed solid from the chlorinated hydrocarbon.
In another embodiment, C.sub.5 -C.sub.10 cycloalkane(s) are isomerized in the presence of a catalyst which has been prepared by heating AlCl.sub.3, at least one sulfur-containing acid (H.sub.2 SO.sub.4 and/or ClSO.sub.3 H and/or FSO.sub.3 H and/or CF.sub.3 SO.sub.3 H) and at least one chlorinated hydrocarbon (preferably CCl.sub.4) at about 40.degree.-90.degree. C., followed by separating the formed solid from the chlorinated hydrocarbon.
