Analytical Carbon Reduction Method Rau Aluminium Hydroxide
Feb 12, 2022
Txoj kev txo cov pa roj carbon monoxide ntawm aluminium hydroxide txhim kho cov khoom siv ntawm cov khoom sib xyaw. Tam sim no, aluminium hydroxide yog qhov chaw kho thiab sib xyaw nrog lwm cov nplaim hluav taws kom txhim kho cov nplaim hluav taws. Txawm li cas los xij, ntau tus neeg siv tsis paub tshwj xeeb txog kev txo cov pa roj carbon monoxide ntawm cov khoom, thiab cov lus qhia ntxaws ntxaws yuav raug qhia kom ntxaws.
Natural gas yog siv los ua qhov kub thiab txias. Cov txheej txheem no tsim cov vapor sib xyaw ntawm cov hlau txhuas, cov nqi qis aluminium oxide thiab carbon monoxide. Cov vapor sib xyaw yog nkag mus rau hauv lwm lub thawv airtight thiab reacts nrog pre-rhuab aluminium hydroxide thiab carbon los ua txhuas carbide, uas yuav carbonized. Aluminium yog nkag mus rau hauv lwm lub nkoj kom hnov mob nrog txhuas oxide los tsim cov hlau txhuas thiab carbon monoxide.
Muaj ntau ntau cov kev tshawb fawb ntawm atmospheric siab carbothermic txo ntawm aluminium hydroxide, thiab muaj ob txoj kev xav ntawm ob-kauj ruam txoj kev thiab peb-kauj ruam txoj kev coj cwj pwm nyob rau hauv tus txheej txheem. Txawm li cas los xij, rau carbothermal chlorination nyob rau hauv lub tshuab nqus tsev, tus cwj pwm ntawm txhuas hydroxide nyob rau hauv cov txheej txheem txhuas smelting ntawm low-valent aluminium chloride txoj kev tseem tsis tau tshaj tawm.
