Abstract

UN PROCESO PARA PRODUCIR SUSTANCIALMENTE HIDROCARBUROS LINEALES POR OLIGOMERIZACION DE UNA OLEFINA BAJA A TEMPERATURA Y PRESION ELEVADAS, COMPRENDE EL CONTACTO DE OLEFINA CON BAJO NUMERO DE CARBONOS EN CONDICIONES DE OLIGOMERIZACION CON ZEOLITA ACIDICA SILICIOSA CON LOS POROS INTERMEDIOS CONSTREÑIDOS, POR EJEMPLO, ZSM-22, -23 O -35, QUE TIENE ACTIVIDAD ACIDA BRONSTED. LA ZEOLITA ES PRETRATADA CON UN ACIDO DICARBOXILICO, POR EJEMPLO, ACIDO OXALICO, EN CONDICIONES PARA EFECTUAR UNA REDUCCION DE POR LO MENOS EL 20 % EN LA ACIDEZ DE LA SUPERFICIE DE LA ZEOLITA, TAL COMO LA DETERMINADA POR LA CONVERSION DEL TRI-TERCIARIOBUTILOBENCENO, SIN REDUCCION SUSTANCIAL DE LA ACTIVIDAD GLOBAL DE LA ZEOLITA COMO LA INDICADA POR EL VALOR ALFA.
