A method of producing iron powder comprises the step of providing a supply of iron oxide powder of a size less than 1000 microns which is then heated in a reducing agent atmosphere to a temperature between 1000&deg; F. and 2100&deg; F., thus resulting in the ironoxide powder being reduced to iron powder, cooling the iron powder in an inert gas atmosphere to a temperature below 150&deg; F. and milling to a median particle size diameter of less than or equal to 20 microns.

This invention relates to a method for controlling the carbon content of metallized iron pellets produced by the continuous direct reduction of iron oxide in a vertical shaft furnace with a reducing gas having a high hydrogen and carbon monoxide content. According to the method, in addition to the standard reducing gases introduced to the reducing zone, methane or methane-containing gas is introduced to the shaft furnace at specified locations beneath the reducing zone and, by controlling the conditions in the furnace, a proportion of the injected gas is reformed in the furnace to reducing gases.

A method of extending the useful life of a catalyst employed in the endothermic catalytic reforming of gaseous hydrocarbons in which a substantial portion of the sulfur contained in such gaseous hydrocarbons is removed by contacting them with an aqueous solution of a water soluble metallic salt having a free metallic ion which forms an insoluble precipitate with sulfur. A preferred salt is zinc chromate.
