2. Ngwọta biochemical nke mmiri mkpofu site na metallurgical coke egweri ntụ ntụ: usoro mgbasa ozi bụ usoro a na-ejikarị agwọ mmiri mkpofu.N'ihi oghere dị n'ime ime nke coke ntụ ntụ na arụmọrụ mgbasa ozi dị mma, ụfọdụ ndị nchọpụta na China emeela nchọpụta banyere ọgwụgwọ coke ntụ ntụ nke ịkwanye mmiri mkpofu.Zhang Jinyong na-eji ntụ ntụ coke nke uzuoku na-eme ka mmiri na-ekpofu mmiri na-ekpo ọkụ na-esi na ihe ọkụkụ na-emepụta ihe.Mgbe adsorption gasịrị, achọrọ oxygen oxygen (COD) nke mmiri mkpofu na-ebelata site na 233mg/L ruo 50mg/L, na-erute ọkọlọtọ mwepụ nke ọkwa mbụ nke mba.Liu Xian et al.eji coke ntụ ntụ maka ọgwụgwọ adsorption nke abụọ nke coking mmiri mkpofu, wee mụọ usoro usoro kwesịrị ekwesị maka coke powder adsorption nke coke waterwater site static and dynamic nọgidere na-eme nnwale.Nsonaazụ nyocha na-egosi na COD nke mmiri mkpofu biochemical mgbe ọgwụgwọ coke ntụ ntụ dị elu nwere ike belata ka ọ bụrụ ihe na-erughị 100mg / L, yana ọnụego mwepụ nke chromaticity nwere ike iru karịa 60%, nke na-emezu ihe achọrọ mma mmiri nke ụlọ ọrụ coking.

3. Ịmepụta coke ntụ ntụ na-egweri metallurgical na ihe mgbakwunye: usoro coke ntụ ntụ n'onwe ya enweghị nrapado, a na-ejikarị ya eme ihe site n'ịgbakwunye ihe nkedo na ya maka ịpị na ịkpụ.Enwere ọtụtụ ụdị ihe mgbakwunye ntụ ntụ coke, na ịdị mma nke coke emepụtara abụghị otu.Liu Baoshan jiri ihe na-emepụta ihe na-emepụta humate, ihe mkpofu starch, coal slime, caustic soda na bentonite dị ka onye na-ejikọta ọnụ iji mụọ ọnụọgụ nke ihe mgbakwunye, ọnọdụ ịkpụzi ntụ ntụ nke coke ntụ ntụ, ọdịdị na akụkụ nke bọọlụ ịkpụzi, na ihicha. okpomọkụ, na A na-anwale bọọlụ ndị a kwadebere ma gbaa ọkụ, na nsonaazụ gosiri na bọọlụ ntụ ntụ nwere ezigbo ike na nkwụsi ike nke okpomọkụ, a pụkwara iji ya mee ka gas artificially.Zhang Liqi jiri coke ntụ ntụ na ihe fọdụrụ tar nke gas na-emepụta na-agwakọta ma na-akpụzi ya dịka akụkụ ụfọdụ si dị, wee mee oxidized na carbonized iji mee coke maka gas.Njirimara nke coke eruola ọkọlọtọ nke coke gasification.Ọ na-enye ndabere usoro maka mmepụta mmepụta ihe.

4. Metallurgical coke-egweri ntụ ntụ na-emepụta metallurgical coke: coke ntụ ntụ na-ejikarị dị ka thinning ihe na coking usoro.Ịgbakwunye ntụ ntụ ntụ ntụ kwesịrị ekwesị na usoro nchịkọta nwere ike imeziwanye ogo nke coke.N'ihi ụkọ na-arịwanye elu nke akụrụngwa coking coal na China, iji gbasaa akụrụngwa coking coal na ibelata ọnụ ahịa nke ngwakọta coal, ọtụtụ ụlọ ọrụ na-agbakọta agbala iji ntụ ntụ coke dị ka ihe na-agwakọta coal maka coke iji meziwanye uru akụ na ụba nke coke. ntụ ntụ.Ọtụtụ ụlọ ọrụ dị na China emeela nyocha gbasara nha nha na oke nke ntụ ntụ coke.Yang Mingping mere nnwale mmepụta ụlọ ọrụ na ndabere nke obere oven oven.Nsonaazụ na-egosi na n'okpuru ọnọdụ usoro coking n'elu-loading, ọ ga-ekwe omume ịgbakwunye 3% na 5% nke ntụ ntụ ntụ iji dochie coal siri ike maka coking.Ogo ngọngọ ahụ mụbara, ọnụ ahịa azụmahịa mụbara ihe dịka 3%.Site na nyocha, Wang Dali et al.chọpụtara na coke na coke ntụ ntụ enweghị mmetụta doro anya na ngosipụta kachasị nke vitrinite nke coal agwakọta.Otú ọ dị, site na nlele microscopic, achọpụtara na ihe ndị dị na coke powder buru ibu karịa 0.2mm nọọrọ onwe ha na coke, ọ na-esikwa ike ijikọta ya na ihe ndị ọzọ, na ọdịdị ahụ agbanweghị;ebe ntụ ọka coke dị obere karịa 0.2mm na-adị mfe site na colloid, nke dị mma maka ịmepụta coke.Nke kacha mma nke coke ntụ ntụ bụ 1.0% -1.7%, ezigbo urughuru size nso bụ 98% -100% erughị 3mm, 78% -80% erughị 1mm, na 40% -50% erughị 0.2mm.

Ọkpụkpọ coke nke ọla bụ ihe a na-apụghị ikewapụ na igwe igwe ihe igwe koke ọla.Dị ka onye na-emepụta ihe igwe igwe na-egweri coke metallurgical, HCMilling (Guilin Hongcheng) na-emepụta.metallurgical coke Raymondigwe nri, metallurgical coke ultra-mmaigwe nri, metallurgical coke vetikalrolaigwe nrina akụrụngwa ndị ọzọ.Ọ nwere ike ịmepụta 80-2500 mesh metallurgical coke powder ma nye nkwado teknụzụ maka ngwa nke coke-egweri ntụ ntụ.
