CATALYST PARTICLES AND ITS USE IN DESULPHURISATION |
摘要 |
<p>The invention relates to catalyst particles comprising nickel in a reduced valence state on a carrier comprising zinc oxide and alumina, wherein the Zn:Ni atomic ratio is at least 12, and the catalyst particles are prepared by: mixing zinc oxide in the form of a powder and alumina or an alumina precursor in the form of a powder; peptising the powder mixture and forming an extrudable dough by adding acid and water to the powder mixture in such amounts that the dough contains 0.8-1.2 moles acid equivalents per kg powder; extruding the extrudable dough to form extrudates; drying and calcining the extrudates; impregnating the extrudates with an aqueous solution of a nickel compound; drying, calcining and reducing the impregnated extrudates. The invention further relates to a process for desulphurisation of a hydrocarbonaceous feedstock using such catalyst particles.</p> |
