Title:
接触水素化リフォーミング方法
Document Type and Number:
Japanese Patent JP4221684
Kind Code:
B2
Abstract:
Hydroreforming and the production of aromatic compounds are carried out in presence of a catalyst comprising a support, a metal of group VIII and an element M chosen from germanium, tin, lead, rhenium, gallium, indium, gold, silver and thallium. The incorporation of M in the catalyst is carried out by dissolving an organometallic compound comprising an M-carbon bond in an aqueous solvent. The catalyst is prepared by: (1) impregnating a support with an aqueous or organic solution of at least a metal of group VIII, filtering, drying, calcining in air and reducing under hydrogen at 20-600 degrees C, preferably 90-500 degrees C; and (2) impregnating the resulting product by an aqueous solution of the additional element M, filtering, drying, reducing and calcining In the preparation of the catalyst, the support is impregnated with an aqueous solution of a compound of the element M, the volume of the aqueous solution being equal or greater than the retention volume of the support. The concentration of M in the aqueous solution of pH 10-14, preferably 10-12, is 0.01-25 mmol/l or 0.5-15 mmol. It is introduced during the elaboration of the catalyst. The feed to be treated contacts the catalyst at 400-700 degrees C and atmospheric pressure-4 MPa with a treated charge flow per unit mass of catalyst between 0.1-10 kg/kgh.
