A process is provided for isomerizing an olefinic hydrocarbon feedstock and producing an olefinic isomerate product, wherein the feedstock comprises at least 10 weight percent of an olefinic hydrocarbon having 5 carbon atoms, comprising contacting the feedstock at isomerization conditions with an isomerization catalyst, the isomerization catalyst comprising from about 0.01 weight percent to about 50 weight percent borosilicate and from about 20 weight percent to about 99.99 weight percent of silica.
