[54] MESOPOROUS CATALYST FOR HYDROCONVERSION OF RESIDUES AND METHOD FOR PREPARING THE LATTER
[57] Abstract: The invention relates to the preparation of a catalyst comprising:- a mainly aluminium oxide calcined support;- a hydro-dehydrogenating active phase comprising at least one metal of group VIB, optionally at least one metal of group VIII, optionally phosphorus, the said catalyst having:- a Sbet specific surface greater than 75 m2/g, - a total pore volume greater than or equal to 0.55 ml/g,- a median mesopore diameter greater than or equal to 16 nm, - a mesopore volume greater than or equal to 0.50 ml/g,- a macropore volume less than 15 % of the total pore volume, the said process comprising at least:a) a first precipitation step of at least one basic precursor and at least one acidic precursor, at least one of the two precursors comprising aluminium, at a pH between 8.5 and 10.5, with a rate of progress of the first step between 5 and 13%, at a temperature between 20 and 90°C and for 2 to 30 minutes;b) a heating step,c) a second precipitation step by addition to the suspension of at least one basic precursor and at least one acidic precursor, in which at least one of the basic or acidic precursors comprises aluminium, with a pH between 8.5 and 10.5 and a rate of progress of the second step between 87 and 95%, d) a filtration step;e) a drying step, f) a moulding step,g) a heat treatment step;h) an impregnation step of the hydro-dehydrogenating active phase on the support obtained in the step g).The invention finally relates to the mesoporous catalyst obtained and its use in hydrotreating or hydroconversion processes of heavy hydrocarbon feedstock.
