Kev Tshawb Fawb Txog Kev Tshawb Fawb thiab Kev Txhim Kho ntawm Kev Siv Hluav Taws Xob Hluav Taws Xob Hluav Taws Xob

Kev loj hlob sai ntawm lub ntiaj teb kev xav tau lub zog tau ua rau txoj hauv kev rau kev txhim kho cov khoom siv hluav taws xob hloov pauv.Txawm li cas los xij, thee tseem ua lub luag haujlwm tseem ceeb hauv lub ntiaj teb lub zog tseem ceeb.Coal suav txog 29% ntawm lub ntiaj teb kev siv hluav taws xob hauv xyoo 2015, thiab nws tau kwv yees. tias los ntawm 2035, thee tseem yuav suav txog 24% ntawm lub zog.Raws li kev lag luam los ntawm cov khoom siv hluav taws xob hluav taws xob, cov hluav taws xob hluav taws xob hluav taws xob yuav nyob twj ywm siab ntev.Coal ya tshauvtau dhau los ua qhov tseem ceeb ntawm kev txhawj xeeb ntawm ib puag ncig vim nws txoj kev sib xyaw ua ke thiab kev kho tsis tsim nyog.Tam sim no, thee ya tshauv yog qhov muaj peev xwm, uas yuav tsum tau siv sai sai rau qhov tsim nyog.Tam sim no, kev siv cov thee ya ya tshauv muaj qhov dav. Qhov ntau ntawm cov teb, tab sis qhov kev siv tus nqi siab yog qhov tsawg.Qhov chaw ntawm kev siv tus nqi siab yog los kawm cov khoom ntawm thee ya tshauv.Coal ya tshauv yog tsim los ntawm cov khoom lossis hollow amorphous spherical hais, irregular unburned carbon hais thiab ntxhia. Cov khoom xws li mullite, quartz, hematite, thiab lwm yam.Nws muaj qee qhov sib txawv ntawm lub cev muaj zog, tshuaj lom neeg muaj pes tsawg leeg thiab cov ntxhia hauv cov hmoov tshauv hauv cov chaw tsim khoom sib txawv.Nws txoj kev siv thiab lub hom phiaj kuj tsis zoo ib yam.Cov complex muaj pes tsawg leeg ntawm thee ya. Cov hmoov tshauv yog ib qho teeb meem loj rau kev siv cov khoom muaj nqis.Txawm li cas los xij, cov khoom siv tau zoo, xws li hollow microspheres, unburned carbon, magnetic cov ntaub ntawv, thiab lwm yam yuav raug cais los ntawm cov complex Cheebtsam los ntawm cov txheej txheem sib cais tsim nyog.Cov tshuaj muaj pes tsawg leeg thiab ntxhia muaj pes tsawg leeg ntawm ya tshauv yog tsawg. -priced raw khoom rau cov khoom muaj nqis ntxiv xws li geopolymers, iav-ceramics thiab zeolites.Cov tshuaj lom neeg muaj pes tsawg leeg thiab cov khoom qub me me ntawm cov pa ya tshauv muaj kev cuam tshuam zoo rau lub zog ntawm geopolymers.Qhov kev ua haujlwm zoo yuav tsum tau txiav txim siab ntawm Raws li cov tshuaj muaj pes tsawg leeg ntawm thee ya tshauv, cov iav-ceramics npaj los ntawm thee ya tshauv mas muaj ob lub tshuab: CaO-Al2O3-SiO2 thiab MgO-Al2O3- SiO2, tab sis lub zog noj ntawm txoj kev npaj yog qhov siab.Qhov ncaj qha sintering txoj kev nrog tsawg zog noj tseem yuav tsum tau kawm ntxiv thiab nrov.Muaj ntau daim ntawv thov kev sim ntawm zeolite synthesized los ntawm thee ya tshauv, tab sis ob peb muaj thwmsim tau nqa. out.Cov kev tshawb fawb theoretical ntawm kev npaj ntawm mesoporous silica thiab silica aerosol thwmsim tsis meej txaus, cov xwm txheej nyuaj rau kev tswj, thiab tseem muaj txoj hauv kev ntev ua ntej kev tsim khoom.
