Abstract:
A catalyst precursor, suitable for use after reduction as a water-gas shift catalyst, is described, which is in the form of a pellet comprising one or more oxides of iron, wherein the catalyst precursor has a pore volume 0.30 cm 3 /g and an average pore size in the range 60 to 140 nm The precursor may be prepared by calcination of precipitated iron compounds at temperatures in the range 400-700° C.

Claim (Index 13):
A method for preparing the pelletized catalyst precursor according to  claim 1  comprising the steps of:\n (i) adding a solution comprising one or more iron salts to a solution comprising an alkali metal carbonate to form a suspension comprising precipitated iron compounds, until the pH of the suspension is in the range of from 2 to 5, \n (ii) adding an alkaline compound to the suspension comprising precipitated iron compounds to raise its pH to \u22657, \n (iii) separating the precipitated iron compounds from the suspension, \n (iv) washing the separated precipitated iron compounds to remove residual alkali metal salts, \n (v) drying the washed precipitate, and \n either (vi) shaping the dried, washed precipitate by pelleting to form a pellet and then calcining the pellet, or, (vi) calcining the dried, washed precipitate and then shaping the calcined material by pelleting to form a pellet, wherein the calcining step is performed at a temperature in the range of from 400 to 700\u00b0 C.
