    摘要: In a method of producing dimethyl ether from a mixed gas containing carbon monoxide and either or both of hydrogen and water vapor or a mixed gas of them further containing carbon dioxide, the improvement which comprises using a mixed catalyst prepared by pulverizing a mixed catalyst containing at least zinc oxide, copper oxide or chrominum oxide, and aluminum oxide, compressing to bind them by a high pressure press and then pulverizing again or a mixed catalyst comprising at least zinc oxide, copper oxide and alumina, in a slurry state formed by suspending in a solvent. In the method of the invention, the yield of dimethyl ether is high, and the conversion water produced through reaction to hydrogen is high. There is no problem of clogging with catalyst, and mechanical strength is not required. Besides, the applicable range of the ratio of carbon monoxide and hydrogen is wide and the reaction is possible in the presence of carbon dioxide in a high concentration. Moreover, affects by impurities and catalyst poisons are small.

    摘要: Disclosed herein is a scrap melting process for the production of molten iron from scrap (as the source of iron) and of high-calorie exhaust gas (as a valuable fuel gas) from pulverized coal (as the principal source of heat and a partial source of high-calorie exhaust gas) and waste plastics (as the principal source of high-calorie exhaust gas and a partial source of heat). The process comprises charging a shaft furnace (equipped with a burner at the tuyere) with scrap (as the iron source) and coke and optional waste plastics from the furnace top and injecting pulverized coal (or pulverized coal plus waste plastics) and oxygen through the burner under specific conditions, so as to mix together pulverized coal (or pulverized coal plus waste plastics) and oxygen, thereby achieving rapid combustion of pulverized coal etc., thereby causing the sensible heat of the combustion gas to melt the scrap and produce molten iron therefrom and recovering the combustion gas as a fuel gas without intentional secondary combustion in the furnace.
