Coking additive for improving coke performance and coking method

Abstract

The invention discloses a coking additive for improving coke performance. The coking additive consists of surface activation catalysts, dissolution aids, penetrating aids and oily solvents, wherein the surface activation catalysts refer to SiC powder and sodium naphthenate; the dissolution aids refer to alpha-hydroxyl propanamide, acetylthiophene and p-toluene sulfonic acid; the penetrating aids refer to polyoxyethylene polyoxypropylene monobutyl ether, polyoxyethylene sorbitan tristearate, chlorophenyl silicone oil and molybdenum triethanolamine; and the oily solvents refer to coal tar, asphalt and residual oil. The coking method comprises the step of adding the coking additive into coal, wherein the addition amount of the additives in the coal is 0.5-3wt%.

Description

technical field [0001] The invention belongs to the technical field of new energy saving, and relates to a coking additive and a coking method for improving coke performance. Background technique [0002] Energy is the material basis of national economic construction. my country's primary energy is mainly coal, and the proportion of coal in primary energy demand is about 70%. According to statistics, in the total amount of coal consumed in my country, the coal directly used for thermal power generation, industrial boilers, industrial kilns and household stoves is as high as 85%. However, due to the traditional way of using coal and low-level combustion efficiency, the contradiction between energy supply and demand in my country is sharp, energy utilization efficiency is low, energy technology is backward, and the unit energy consumption of major industrial products is 20-50% higher than that of advanced countries. At the same time, due to the direct combustion of a large a...
