Abstract:
The process for removing metal carbonyls and moisture from a gas, including moisture formed as a result of removal of metal carbonyls from said gas which comprises intimately contacting said gas with a particulate composition suitable for removing a metal carbonyl composition and moisture from a gas as well as for removing a moisture by- product formed during removal of said carbonyl composition from said gas which comprises:a particulate mixture having a surface area greater than 50 m.sup.2 /g comprising (a) first particles having a surface formed of a first composition having a reduction potential greater than about 0.175 volts selected from the group consisting of a metal oxide, an organometallic oxide and mixtures thereof and (b) second particles having a surface formed of a second composition capable of removing moisture from said gas, said second composition comprising a metal halide of the formula MX.sub.y wherein X is halogen, M is a y-valent metal wherein said metal halide is formed from a compound of said y-valent metal which is alkylated or which has pendant functional groups reactive with hydrogen halide and wherein a heat of formation of the hydrated metal halide (MX.sub.y.(H.sub.2 O).sub.n) of said metal is greater than or equal to 10.1 kilocalories per mole of hydrated halide for each hydrated water molecule wherein n is the number of water molecules bound to the hydrated metal halide and y is an integer from 1 to 3,and recovering said gas after contacting said particulate composition.
