Abstract

The invention relates to the field of chemical industry and discloses a method for producing Fischer-Tropsch chemicals by using coke oven gas and converter gas. The method comprises the following steps: (A) purifying the coke oven gas so as to obtain H2-containing first product gas; (B) treating the converter gas so as to obtain CO-containing second product gas; (C) preparing Fischer-Tropsch synthesis gas from the first product gas and the second product gas, wherein the mole ratio of H2 to CO in the Fischer-Tropsch synthesis gas is 2 to 2.5; and (D) putting the Fischer-Tropsch synthesis gas into a Fischer-Tropsch synthesis unit, and carrying out synthesis under the action of certain pressure and temperature, so as to obtain a liquid phase, i.e., the Fischer-Tropsch chemicals. According to the method, the production of high-added-value chemicals by making full use of exhaust gases of steel works is achieved, the economic benefit of the steel works is effectively improved, and the method is environmentally friendly and energy-saving.

Description

technical field [0001] The invention relates to the field of chemical industry, in particular to a method for producing Fischer-Tropsch chemicals by utilizing coke oven gas and converter gas. Background technique [0002] Coke oven gas is a by-product produced during the coking process of coking plants and steel plants. Its main components are hydrogen and methane, as well as a small amount of olefins, carbon monoxide and carbon dioxide, and trace impurities such as tar, naphthalene, ammonia, and hydrogen sulfide. Most of the previous coke oven gas was used as fuel, but now coke oven gas can be used to extract hydrogen, to produce methanol through conversion, and to produce liquefied natural gas through methanation. However, due to the high inert gas content and low calorific value of the converter gas in most steel plants, most of it is discharged as waste, which not only pollutes the environment but also wastes resources. [0003] Converter gas is the waste gas discharged...
