SUMMARY:

Three bentonite clays from deposits located in the interior of Paraíba State were used to study the pillarization parameters such as the temperature and dilution of the aluminum pillaring agent. As well as the synthesis of pillarization using nickel as the pillar-forming metal, in addition, the impregnation of nickel in pillarized clays was studied for application in ethylene oligomerization reactions. The samples were characterized by X-ray diffraction and nitrogen sorption at 77 K. It was observed through the study of the temperature decrease that it is possible to obtain a pillar material without heating during the preparation of the pillar agent, as well as If pillar samples were obtained with 25% and 50% of the amount of aluminum pillaring agent commonly used, with these samples it was possible to prove that it is possible to insert new pillars in an already pillarized material. It was observed that during the synthesis studies of a nickel abutment the best result was obtained by preparing an Al / Ni mixed abutment, in addition to studying the impregnation of nickel in columnar clay samples with different aluminum percentages. As next steps, more characterization of the materials already obtained will be performed besides their application in the ethylene oligomerization reaction.
