PROCESS FOR THE PREPARATION OF A SULPHUR RECUPERATION CATALYST IN REFINERIES THROUGH THE CLAUS PROCESS

A process for the preparation of a sulphur recuperation catalyst in refineries, through the Claus process, characterized by the steps of: to prepare a mixture made of an oxide of the group II and IV and an organic solvent in inert atmosphere to avoid the mixture precipitating; to prepare an aqueous solution containing magnesium and calcium ions with a lightly acid pH; to calcinate a support made of alumine to a comprised temperature between 60 and 120 degree C during a lapse of 4 to 24 hours; to impregnate the support with the mixture made of titanium oxide and to shake to a comprised temperature between 65 and 100 degree C during 24 hours; to dry the support obtained in the previous stage during a lapse of 4 to 24 hours and to calcinate the support to a temperature of 450 degree C during a period of 2 to 6 hours. The invention also relates to the resulting catalyst of the process mentioned. Un procedimiento para la preparacion de un catalizador de recuperacion de azufre en refinerías, mediante el proceso Claus, caracterizado porque comprende los pasos de: preparar una mezcla a base de un oxido del grupo II y IV y un solvente orgánico, en atmosfera inerte para evitar que precipite la mezcla; preparar una solucion acuosa conteniendo iones de magnesio y calcio con un pH ligeramente ácido; calcinar un soporte a base de alumina a una temperatura comprendida entre 60 y 120 degree C durante un tiempo de 4 a 24 horas; impregnar el soporte con la mezcla a base de oxido de titanio y agitar a una temperatura comprendida entre 65 y 100 degree C durante 24 horas; secar el soporte obtenido en la etapa anterior durante un tiempo de 4 a 24 horas y calcinar el soporte a una temperatura de 450 degree C durante un período de 2 a 6 horas. La invencion también se relaciona con el catalizador resultante del procedimiento mencionado.
