接触法制硫酸（Contact process sulfuric acid） Contact process sulfuric acid Discussion on comprehensive economic benefit of sulphuric acid industry I. key and difficult points 1, industrial production of sulfuric acid raw materials. 2. The chemical reaction principle, main production process and typical equipment of sulphuric acid made from pyrite. 3, environmental protection and comprehensive utilization of raw materials and energy. Two, example points First order [1]] what do you think is the possible way to reduce acid rain? Use less coal as fuel; build up the factory chimneys; fuel the desulfurization; add lime to the acidified soil; develop new energy sources A., B., C., D. [Pathfinder] Effective precautions can only be taken by knowing the pathways that lead to acid rain [answer] The main cause of acid rain is a large number of SO2 emissions to the atmosphere, and less sulfur coal as fuel, or fuel desulfurization, and the development of new energy, can reduce the production of SO2, thereby reducing the production of acid rain. So choose the answer C. [commentary] knowledge about environmental protection is one of the hot topics in the recent college entrance examination, and it is one of the hot topics in the college entrance examination. [2] automobile exhaust (containing hydrocarbons, CO, SO2 and NO) is a source of air pollution in the city. One way to do this is to put a catalytic converter on the exhaust pipe of a car (with platinum and palladium alloy as a catalyst). It is characterized by the reaction of CO with NO, the formation of non-toxic gas that can participate in the atmospheric environment circulation, and the combustion of hydrocarbons and the transformation of SO2. (1) write out the chemical equation for the reaction of carbon monoxide with nitric oxide:. (2) the drawback of a catalytic converter is to increase the acidity of the air to a certain extent. (3) the method of controlling air pollution sources in cities can be. A. develops hydrogen energy,
