Abstract: The present invention provides a process for separating a condensable gas from a non-condensable gas by switching at least three adsorber beds which preferentially adsorb the condensable gas serially through the following steps:(a) an adsorption step in which a mixture of the condensable and non-condensable gases are passed through the bed and the separated non-condensable gas is withdrawn therefrom;(b) a supercharging step in which a stream relatively rich in the condensable gas is passed through the bed, the stream having an actual volume at least three times that necessary to displace a void volume of the bed;(c) a desorption step in which a vacuum is drawn on the bed and an amount of a non-condensable gas is bled through the bed;and wherein the non-condensable gas in conjunction with entrained condensable gas from step (c) is passed into a vacuum pump, is compressed, at least some of the condensable gas is condensed and at least part of the non-condensable gas and remaining condensable gas is the passed t

Abstract: Mixed alcohols are produced from carbon monoxide and hydrogen gases using an easily prepared catalyst/co-catalyst metal catalyst. The catalyst metals are molybdenum, tungsten or rhenium. The co-catalyst metals are cobalt, nickel or iron. The catalyst is promoted with a Fischer-Tropsch promoter like an alkali or alkaline earth series metal or a smaller amount of thorium and is further treated by sulfiding. The composition of the mixed alcohols fraction can be selected by selecting the extent of intimate contact among the catalytic components.
