    摘要： A method for passivating low-alloy steel surfaces in apparatus operating in the temperature range 350 to 580° C. and exposed to a carbon monoxide containing gas mixture comprises adding a passivating compound containing at least one phosphorus (P) atom to the gas mixture. The gas mixture is preferably a reformed gas and also described is a process for producing a synthesis gas wherein, prior to cooling a reformed gas mixture to a temperature between 350 and 580° C. in apparatus having low-alloy steel surfaces downstream of one or more reforming steps, a passivating compound containing at least one phosphorus (P) atom is combined with the gas mixture.

    摘要： Compositions suitable for use as oxidation catalysts essentially free from elements, or compounds thereof, of Group VIII of the Periodic Table, comprise an intimate mixture of oxides of at least three elements selected from Groups IIIa and IVa of the Periodic Table, including, of the total number of Group IIIa and IVa element atoms present, a) a total of at least 60% of atoms of at least one element X selected from cerium, zirconium, and hafnium, b) a total of at least 5% of atoms of at least one other element Y different from element X and selected from the variable valency elements titanium, cerium, praseodymium, and terbium; and c) a total of at least 5% of atoms of at least one element Z differing from X and Y and selected from Group IIIa elements. Such composition, and similar two component compositions wherein X and Y are both cerium, have, after heating for 8 hours at 1200.degree. C., a BET surface area of at least 1 m.sup.2 .multidot.g.sup.-1 and are particularly useful for the oxidation of a feedstock with an oxygen-containing gas, e.g. catalytic combustion, especially under conditions such that the catalyst attains a temperature of at least 1000.degree. C.

    摘要： A process for passivation of surfaces of heat exchange apparatus exposed to a synthesis gas containing carbon monoxide, includes the steps of: adding arsine to the synthesis gas to provide a total As concentration in the synthesis gas in range 0.001 to 10 ppmv, (ii) exposing the mixture of hot synthesis gas and arsine to the shell-side surfaces of said heat exchange apparatus to reduce the interaction between the carbon monoxide present in said gas and metals in said surfaces, (iii) recovering a cooled synthesis gas from the shell-side of said apparatus, and (iv) passing the cooled synthesis gas, optionally after further cooling, through a sorbent bed to remove arsenic compounds from the synthesis gas.
