Abstract
A hydroprocessing catalyst has been developed. The catalyst is formed from a unique transition metal molybdotungsten oxy-hydroxide material. The hydroprocessing using the transition metal molybdotungsten oxy-hydroxide material-based catalyst may include hydrodenitrification, hydrodesulfurization, hydrodemetallation, hydrodesilication, hydrodearomatization, hydroisomerization, hydrotreating, hydrofining, and hydrocracking.
Claims12
A conversion process comprising contacting a feed with a catalyst at conversion conditions to provide at least one product, the catalyst comprising a component produced upon decomposition by sulfidation of a transition metal molybdotungsten oxy-hydroxide material having the formula:
- Sa(NH4)bM(OH)cMoxWyOz
- where ‘S’ is selected from glucose, fructose, galactose, lactose, maltose, sucrose, and mixtures thereof;
- ‘a’ varies between 0.001 to 5;
- ‘b’ varies between 0.1 and 3;
- ‘M’ is a metal selected from Mg, Mn, Fe, Co Ni, Cu, Zn and mixtures thereof;
- ‘c’ varies from 0.1 to 2;
- ‘x’ varies from 0.01 to 1;
- ‘y’ varies from 0.1 to 4;
- the sum of (x+y) must be ≤4.0;
- z is a number which satisfies the sum of the valences of M, b, c, x and y;
- the material having a poorly crystalline x-ray powder diffraction pattern showing a broad peak between d-spacing 4.45 and 2.25 Å.
