Embodiment 1

[0033] A process for preparing active coke, comprising the following steps:

[0034] Step 1, using biochar to prepare the primary product of activated coke;

[0035] Step 2, weighing diethyl nicotinamide and adding it to acetone, stirring until completely dissolved to obtain an activator;

[0036] Step 3, using the activator to treat the initial active coke product to obtain the active coke product.

[0037] Wherein, the biochar is obtained from agricultural by-products through biomass dry distillation; the agricultural by-products include rice husks, wheat straw, cottonseed husks, peanut shells, fruit shells, bagasse, fruit peels, vines and corn cobs. one or more.

[0038] The step 1 is specifically:

[0039] S1. After removing impurities, the biochar is pulverized and sieved to obtain biochar powder with a particle size of 0.5-1mm;

Abstract

The invention relates to an active coke preparation process. The preparation process comprises the following steps: step 1, preparing an active coke initial product by using biomass charcoal; step 2,weighing diethyl nicotinamide, adding diethyl nicotinamide into acetone, and stirring until diethyl nicotinamide is completely dissolved to obtain an activating agent; and step 3, treating the activated coke initial product by using the activating agent to obtain the product activated coke. According to the invention, the problems of low adsorption desulfurization capacity and large usage amount of active coke in industrial application at present are solved. The surface-modified desulfurized active coke prepared by the invention has dual functions of chemical catalytic desulfurization and adsorption desulfurization, has the characteristic of higher desulfurization reaction efficiency compared with the existing desulfurized active coke mainly based on adsorption, and can be regenerated by steam heating after being used.

Description

technical field [0001] The invention relates to the field of active coke preparation, in particular to an active coke preparation process. Background technique [0002] With the rapid economic development, the requirements of various countries for environmental protection are also increasing, and energy conservation and emission reduction has become the most concerned environmental protection goal in the world today. In recent years, desulfurization flue gas purification methods have become an important measure for national environmental protection. As the thermal power industry’s mandatory boiler flue gas purification treatment is coming to an end, more and more non-thermal power high-temperature process flue gas needs to be desulfurized. The original traditional The desulfurization process can no longer meet the needs of this type of market, and the activated coke desulfurization process gradually shows its adaptability to this type of market. [0003] Activated coke desu...
