Abstract

The isomerization of n-pentane on zirconia, sulfated zirconia and promoted with 2.0 wt % Cu sulfated zirconia(Cu/SZrO) has been studied. It was found the influence of hydrogen and oxygen on the n-pentaneisomerization. It is supposed, that isomerization on the Cu/SZrO catalyst it is substantially carried out throughinteraction olefin with the proton acid centres of a surface.
