Studies of the use of a soil from river Pardo basin located at the Ribeirão Preto region, were realized with the aim of preparing catalysts. A clay, high purity kaolin type, was obtained after purification followed by treatment with acid and then calcined. The activity and selectivity of the catalysts were determined using cycloexene as substrate. The majority of the catalysts obtained yield a conversion higher than 70%
