Abstract
This invention discloses coking additive and method for coking. The invention uses a certain proportion of anthracite, lean coal, blind coal and coking additive as the raw materials, and can obtain high quality coke. The coking additive is composed of coking agent and coking assistant. The coking agent comprises coal tar, pitch and residual oil. The coking assistant is (1) water-soluble organic macromolecular compound, such as cellulose salt, polyacry lamide, sodium polyacrylate, hexanolactam and PVA, or (2) nonwater-soluble oil and ester emulsion, such as machine oil, diesel oil, plant oil, animal oil and rosin emulsion, or (3) catalyst and crosslinker, such as aluminum chloride, iron chloride, 1-cyanocarbamidine, hexamethenyl fouramine and resorcin. The method can obtain high quality coke from 80% lean coal and 20% anthracite, or 100% blind coal, or coke with up to 40% anthracite.
Description
Technical field
The invention belongs to the coking technology field, is a kind of coking additire and coking process.
Background technology
The coke-oven plant mainly adopts coking coal at present, 1/3 coking coal, rich coal coking, but coking coal only accounts for about 10% of world's coal reserves, though China is higher, also only accounts for about 27%, and meets field conditions still less, therefore coke-oven plant's employing hard coal, meager coal, lean coal coking are that the alleviation coking coal is under-supply, the effective way that reduces cost.Hard coal fixed carbon content height particularly, coking coke recovery height, adding anthracite cocking is the main direction of present coking industry, but at present can only be at formed coke, make Jiao Zhongneng firm by ramming and allocate a small amount of hard coal into.
Summary of the invention
The purpose of this invention is to provide a kind of coking additire and coking process, adopt coking additire of the present invention and coking process, the lean coal that 80% meager coal can be added 20% coking coal or 100% is produced high-quality Jiao, perhaps adds in rich coal, coking coal and can produce high-quality Jiao up to 40% hard coal.
Solution of the present invention is as follows: earlier coking coal, rich coal and hard coal are pressed (0.3～5): 1 mixed is crushed to granularity less than 0.1 millimeter account for more than 70%, be preferably 100～200 orders, mix with the coking coal and the coking additire of the present invention of other preparation again, go into stove coking.Coking additire has two kinds with the order that mixes of coal: 1. coking additire is mixed pulverizing with fertile coking coal and hard coal, be mixed into coking coal with other coking coal again; 2. earlier fertilizer, coking coal are mixed pulverizing with hard coal, more chippy mixing fine coal and other coking coal and coking additire are mixed into coking coal.
Use and add 20% coking coal up to 80% meager coal and add coking additire of the present invention or add coking additire of the present invention and also be made into coking coal with 100% lean coal.
Coking additire of the present invention is made up of coking agent and coking promotor, and the coking agent comprises coal tar, tar-bitumen, petroleum pitch, residual oil etc.Coking promotor comprises three classes: 1. water-soluble organic macromolecule compound: as cellulosate, polyacrylamide, sodium alginate, sodium polyacrylate, hexanolactam, resol, polyvinyl alcohol, furfural, furfuryl alcohol, chaff ketone, vegetable jelly, gelatin, lipid acid (potassium, sodium, amine) salt etc.; The emulsion of 2. water-insoluble oil and fat (ester): as the emulsion of machine oil, diesel oil, silicone oil, vegetables oil, animal oil, rosin (fat), naphthenic acid, vinyl acetate between to for plastic glyceryl ester etc.; 3. catalyzer and linking agent: as aluminum chloride, iron(ic) chloride, 1-dicyanodiamide, hexamethylenetetramine, Resorcinol etc.
Coking additire compound method of the present invention is as follows: it is mixed according to a certain percentage by a kind of of a kind of of coking agent or several and coking promotor or several, as adopts 5～50% emulsified bitumen and 1～10% sodium polyacrylate by bitumen emulsion: sodium polyacrylate solution=1～10: 1 proportioning is mixed just becomes a kind of coking additire; Also become a kind of coking additire with 78% coal tar+20% crude benzol+1% machine oil+1% turps mixing and stirring.
Coking additire accounts for 0.1～20% of the coking coal that matches.
Embodiment
Embodiment 1: form a kind of coking additire with the gelatin of the emulsification tar-bitumen of concentration 30% and concentration 5% by 5: 1 mixed, again in the adding that has prepared add 5% above-mentioned additive in the 30% anthracitic coking coal and mix and can go into stove coking.
Embodiment 2: adopt 75% coal tar+22% crude benzol+2% machine oil+1% turps to be mixed into coking additire, again in the adding for preparing add this coking additire of 4% in the 35% anthracitic coking coal and mix and can go into stove coking.
Embodiment 3: the sodium polyacrylate (concentration 1%) that adds 5% emulsification rosin (concentration 10%) and 10% in having added 20% anthracitic coking coal mixes can go into stove coking.
Claims (6)
