Abstract: A method of producing a support, and supported catalyst, the method comprising: (a) combining a porous inorganic oxide catalyst carrier or carrier extrudate with an aqueous solution, dispersion or suspension comprising: (i) a boron-containing source; and (ii) an organic compound or organic chelating agent selected from organic compounds comprising at least two oxygen atoms and 2-10 carbon atoms; (b) calcining the composition (a) to reduce its Loss on Ignition (LOI) volatiles content to greater than 0 wt % to less than about 5 wt %; (c) impregnating the calcined composition an aqueous composition comprising at least one each of a Group VIB and Group VIIIB metal-containing source; and (d) calcining, to reduce its LOI volatiles content greater than 0 wt % to less than about 30 wt %; wherein the boron content of a supported catalyst is in the range of about 1 wt % to about 13 wt B2O3 based on the total weight of the catalyst.
