Lignite, Kuj tau hu ua Semi-Coke, yog cov khoom siv roj teeb tawm los ntawm cov thee los ntawm tsawg kub distillation thev naus laus zis. Nyob rau hauv xyoo tsis ntev los no, nrog kev loj hlob ntawm thoob ntiaj teb siv rau cov ntaub ntawv huv si thiab cov neeg ua haujlwm ib puag ncig, tshuaj lom neeg vim nws cov txiaj ntsig tshwj xeeb.
Lignite yog feem ntau tsim los ntawm cov distillation tsawg-distillation, thiab qhov ntsuas kub yog tswj tau ntawm 500 thiab 800 degrees Celsius. Piv nrog tsoosal thee kev sib txuas, cov txheej txheem no tuaj yeem txo cov tshuaj uas muaj teeb meem thiab cov pa roj carbon ntau cov ntsiab lus thiab tus nqi calorific. Cov ntaub ntawv qhia tau hais tias tus nqi calorific ntawm lignite tuaj yeem ncav cuag 5500 mus rau 7000 kcal, uas yog ze rau kev xaiv hluav taws xob zoo, ua rau muaj kev tiv thaiv lub zog thiab ib puag ncig cov yam ntxwv.
Hauv daim teb ntawm daim ntawv thov, Lignite qhia muaj ntau yam peev xwm. Hauv kev lag luam metallurgical, ligrite tuaj yeem siv los ua lub zog ua kom sov los hloov ib feem, txo cov nqi tsim khoom thiab txo cov roj carbon monissions. Hauv kev lag luam tshuaj, lub lignite tuaj yeem siv los tsim cov khoom lag luam xws li calcium carbide thiab ua haujlwm carbon. Nws cov ntoo tshauv qis thiab cov tub rog sulfur pab tau los txhim kho cov khoom ntshiab ntawm cov khoom hauv qab. Tsis tas li ntawd, lub tsev nyob tseem dav nyob rau hauv cov huab cua cua sov thiab cov lag luam roj hmab, tshwj xeeb hauv cov chaw nrog kev tiv thaiv kev tiv thaiv kev tiv thaiv kev tiv thaiv kev tiv thaiv kev tiv thaiv kev tiv thaiv kev tiv thaiv siab. Nws cov yam ntxwv tsis muaj kuab paug ua rau nws muaj qhov zoo hloov rau cov tshuaj thee zoo li qub.
Los ntawm cov kev pom ntawm kev ua lag luam thoob ntiaj teb, qhov kev thov rau lignite yog loj hlob ruaj khov. Qhov kev thov rau lub zog huv hauv ntau lub teb chaws tau tsav cov export ntawm nplooj lig, tshwj xeeb tshaj yog nyob rau sab qab teb Asia, Middle East thiab Europe. Vim yog nws cov kev zoo ib puag ncig thiab kev txhawb nqa txoj cai, ligrite tau txuas ntxiv nthuav nws cov lag luam sib koom. Nyob rau tib lub sijhawm, nrog kev nce qib ntawm cov thev naus laus zis tshuab ntau lawm, cov nqi ntau lawm ntawm lub lignite tau txo qis, ntxiv txhim kho nws cov kev ua lag luam kev sib tw.
Nyob rau yav tom ntej, raws li lub zog thoob ntiaj teb qauv hloov mus rau cov pa roj carbonancation tsawg, lub lignite yuav tsum ua lub luag haujlwm tseem ceeb hauv cov teb uas dav dav. Nws cov yam ntxwv siab thiab huv tib yam tsis yog ua raws li cov qauv ntawm kev loj hlob ntawm kev ruaj khov, tab sis kuj tseem yuav cov ntsiab lus loj hlob tshiab rau cov saw muaj cov saw muaj.
