The invention discloses an industrial sludge resource treatment method, which belongs to the technical field of harmless disposal of industrial sludge, and comprises a sludge sorting and mixing step, a sludge transporting step, a hydrothermal reaction step, a plate and frame filter press dehydration step, Sludge drying steps, cracking steps, plasma gasification steps and tail gas treatment steps are a method that can effectively utilize the calorific value of sludge, recover the potential heat energy in it, recover the metal part, melt the remaining inorganic substances into glass, and convert the remaining Heavy metals are wrapped in it and can be used as building materials, avoiding the harm of heavy metals entering the water body, and basically achieving zero discharge of pollutants. Industrial sludge resource treatment method.

The invention relates to a method for producing low-sulfur gasoline, which comprises the following steps that: firstly, gasoline raw materials are fractionated into light and heavy gasoline fractions, the light gasoline fractions are subjected to alkali washing for removing sulfur and alcohol, the heavy gasoline fractions are subjected to catalytic hydrogenation for removing sulfur-containing compounds, the heavy gasoline fractions after the hydrogenation desulfuration are introduced into a counter flow reactor from the middle part, hydrogenation sulfur and alcohol removal catalysts are filled in positions under a material inlet of the counter flow reactor, hydrogen-rich gas is introduced from the bottom of the reactor, a part of heavy gasoline fractions are vaporized into gas phase ingredients and liquid phase ingredients, the liquid phase ingredients flow from top to bottom and are in count flow contact with hydrogen gas on the catalysts for carrying out hydrogenation sulfur and alcohol removal reaction, the liquid phase ingredients after the sulfur and alcohol removal flow out from the bottom of the reactor, the gas phase ingredients and other gas are discharged out from the top of the reactor, the gas phase ingredients after the condensation are mixed with the liquid phase ingredients discharged from the bottom of the tower and the light gasoline fractions subjected to the alkali washing for removing sulfur and alcohol to obtain gasoline products. When the method provided by the invention is adopted, the gasoline product with the sulfur and alcohol sulfur content lower than 3mug / g can be producted, and simultaneously, the total sulfur content of the gasoline product is reduced.
