N'ihi na ntụ ntụ coke nwere ihe onwunwe nke nnukwu carbon, oghere dị n'ime ya mepụtara, na ike ụfọdụ, ndị nchọpụta sayensị China emeela nnyocha sara mbara na nke miri emi gbasara otu esi eji ntụ ntụ coke n'afọ ndị na-adịbeghị anya. HCMilling (Guilin Hongcheng) bụ onye na-emepụta nkekọlaịkị ígwèigwe igwe egweri iheIhe na-esonụ bụ okwu mmalite maka ojiji nke igwe igwe e ji ígwè gweri ihe na kọla:

1. Kabọn a na-arụ ọrụ site na ntụ ntụ igwe na-egweri kọlọ: Kabọn a na-arụ ọrụ bụ ihe e ji emepụta kabọn nke nwere usoro microporous na ikike adsorption siri ike. A na-ejikarị ya eme ihe n'ọtụtụ ebe dịka ụlọ ọrụ kemịkalụ, nhazi nri, nchedo ndị agha na ụlọ ọrụ nchekwa gburugburu ebe obibi. Arụmọrụ nke kabọn a na-arụ ọrụ metụtara mpaghara elu ya kpọmkwem, olu micropore, nkesa nha pore na ihe mejupụtara kemịkalụ. Ugbu a, ihe ndị bụ isi maka nkwadebe ụlọ ọrụ mmepụta ihe nke kabọn a na-arụ ọrụ na mba m bụ osisi na kol. N'afọ ndị na-adịbeghị anya, n'ihi ụkọ ike na-abawanye na mba ahụ na-elekwasị anya na nchekwa gburugburu ebe obibi, ndị mmadụ na-achọ ihe ndị ọzọ maka nkwadebe nke kabọn a na-arụ ọrụ. Ntụ ntụ kọlọ bụ ihe sitere na ụlọ ọrụ coking. O nwere oke kabọn a kapịrị ọnụ, obere ihe na-agbanwe agbanwe na ntụ, ike dị elu, na nnweta dị mfe nke ihe ndị e ji emepụta. Ọ bụ ihe dị mma maka ịkwadebe kabọn a na-arụ ọrụ. Ugbu a, a na-emepụta kabọn a na-arụ ọrụ karịsịa site na ịgwọ ntụ ntụ kọlọ site na mkpali anụ ahụ na mkpali kemịkalụ. Usoro mkpali anụ ahụ chọrọ ka a ga-eme ka ihe ndị e ji emepụta ihe dị mkpa ka emee ya, wee rụọ ọrụ na okpomọkụ 600 ruo 1200°C. Ihe na-eme ka ihe na-akpali akpali gụnyere gas ndị na-eme ka ihe dị ka CO2 na mmiri na-agbaze, a na-ejikwa atọm carbon dị na ihe na-eme ka ihe dị na carbon oxide dị na gas ahụ na-agafe. A na-emepụta carbon a na-arụ ọrụ nke nwere oghere ndị mepere emepe nke ọma site na ọrụ nke imepe, ịgbasa na ịmepụta oghere ọhụrụ. Mmelite kemịkalụ na-ezo aka n'ịgwakọta ihe ndị e ji arụ ọrụ na ihe ndị na-eme ka ihe dị ndụ rụọ ọrụ (alkali metal na alkali metal hydroxides, nnu inorganic na ụfọdụ acid) n'otu oke, na-emikpu ha ruo oge ụfọdụ, wee mechaa usoro carbonization na activation n'otu nzọụkwụ.

2. Ọgwụgwọ mmiri mkpofu biochemical site na iji ntụ ntụ coke igwekota: usoro adsorption bụ usoro a na-ejikarị agwọ mmiri mkpofu coking. N'ihi oghere dị n'ime nke ntụ coke na arụmọrụ adsorption dị mma, ụfọdụ ndị nchọpụta na China emeela nnyocha na ọgwụgwọ ntụ ntụ coke nke mmiri mkpofu coking. Zhang Jinyong na-eji ntụ ntụ coke nke steam na-arụ ọrụ iji dọpụta mmiri mkpofu biochemical site na osisi coking. Mgbe adsorption gasịrị, a na-ebelata ọchịchọ oxygen kemịkalụ (COD) nke mmiri mkpofu site na 233mg/L ruo 50mg/L, na-erute ọkọlọtọ mwepụta nke ọkwa mbụ nke mba. Liu Xian na ndị otu ya jiri ntụ ntụ coke maka ọgwụgwọ adsorption nke abụọ nke mmiri mkpofu coking, ma mụọ ọnọdụ usoro kwesịrị ekwesị maka adsorption ntụ ntụ coke nke mmiri mkpofu coking site na nnwale na-aga n'ihu na nke na-agbanwe agbanwe. Nsonaazụ nnyocha ahụ gosiri na enwere ike ibelata COD nke mmiri mkpofu kemịkalụ mgbe emechara ọgwụgwọ ntụ ntụ coke dị elu ruo ihe na-erughị 100mg/L, yana ọnụego mwepụ chromaticity nwere ike iru ihe karịrị 60%, nke na-emezu ihe achọrọ maka ịdị mma mmiri nke ụlọ ọrụ coking.

3. Ịmepụta ntụ ntụ coke metallurgical na-egweri ihe na mgbakwunye: usoro ntụ ntụ coke n'onwe ya enweghị nrapado, a na-ejikarị ya eme ihe site n'itinye ihe njikọta na ya maka ịpị na ịkpụ. E nwere ọtụtụ ụdị ihe mgbakwunye ntụ ntụ coke, ụdị coal e mepụtara abụghịkwa otu. Liu Baoshan jiri ihe na-agwakọta nke humate, ihe fọdụrụ na starch, coal slime, caustic soda na bentonite dị ka ihe njikọta iji mụọ ọnụọgụ ihe mgbakwunye, ọnọdụ ịkpụzi ntụ ntụ coke, ọdịdị na nha nke bọọlụ ịkpụzi, na okpomọkụ nkụ, na bọọlụ ndị a kwadebere anwale ma gbaa ọkụ, nsonaazụ ya gosiri na bọọlụ ntụ ntụ coke nwere ike dị mma na nkwụsi ike okpomọkụ, enwere ike iji ya mepụta gas site na aka. Zhang Liqi jiri ntụ ntụ coke na ihe fọdụrụ na tar nke onye na-emepụta gas mepụtara gwakọta ma kpụzie ya dịka oke ụfọdụ si dị, wee mee ka ọ dị ọcha ma mee ka ọ dị ka carbon iji mee coke maka gasification. Njirimara nke coke erutela ọkọlọtọ nke coke gasification. Ọ na-enye ntọala echiche maka mmepụta ụlọ ọrụ.

4. Ntụ ntụ ntụ coke e ji ígwè kpụọ iji mepụta coke metallurgical: A na-ejikarị ntụ ntụ coke eme ihe dị ka ihe na-eme ka coke dị mfe n'usoro coking. Ịtinye ntụ ntụ coke kwesịrị ekwesị n'usoro coking nwere ike ime ka mma coke dịkwuo mma. N'ihi ụkọ akụrụngwa coke coking na China na-abawanye, iji gbasaa akụrụngwa coke coking ma belata ọnụ ahịa ngwakọta coal, ọtụtụ ụlọ ọrụ coking agbalịala iji ntụ ntụ coke dị ka ihe mejupụtara ngwakọta coal maka coking iji melite uru akụ na ụba nke ntụ ntụ coke. Ọtụtụ ụlọ ọrụ na China emeela nchọpụta na nha na oke nke ntụ ntụ coke. Yang Mingping mere ule mmepụta ụlọ ọrụ dabere na obere ule oven coke. Nsonaazụ ya na-egosi na n'okpuru ọnọdụ usoro coking a na-ejikarị ebuli elu, ọ ga-ekwe omume ịgbakwunye 3% ruo 5% nke ntụ ntụ coke iji dochie coal dị nro maka coking. Ogo ngọngọ ahụ mụbara, ọnụego azụmahịa ahụ mụbara site na ihe dị ka 3%. Site na nyocha, Wang Dali na ndị otu ya chọpụtara na coking na ntụ ntụ coke enweghị mmetụta doro anya na ngosipụta kachasị nke vitrinite nke coal agwakọtara. Agbanyeghị, site na nha obere ihe dị n'ime ya, achọpụtara na ntụ ntụ coke karịrị 0.2mm nọọrọ onwe ha n'ime coke ahụ, ọ na-esikwa ike ijikọ ya na ihe ndị ọzọ, ọdịdị ya agbanweghịkwa; ebe ntụ ntụ coke nke pere mpe karịa 0.2mm ka ejiri colloid kechie ya ngwa ngwa, nke dị mma maka nhazi coke. Oke kachasị mma nke ntụ ntụ coke bụ 1.0%-1.7%, oke nha mkpụrụ ahụ kacha mma bụ 98%-100% obere karịa 3mm, 78%-80% obere karịa 1mm, na 40%-50% obere karịa 0.2mm.

A naghị ekewapụ igwe e ji ígwè gwerie ihe na igwe e ji ígwè gwerie ihe. Dịka onye na-emepụta igwe e ji ígwè gwerie ihe, HCMalling (Guilin Hongcheng) na-emepụta igwe e ji ígwè gwerie ihe.kọlaịkị ígwè Raymondigwe igwe, kọlaịkị ígwè dị oke mmaigwe igwe, kọlaịkị ígwè kwụ ọtọihe eji agba ígwèigwe igwena ngwa ndị ọzọ.
