Nkọwa na Atụmatụ

Nkọwa: WNX na-eji teknụzụ mmepụta akpaaka dị elu ma na-eji ihe eji emepụta ihe dị elu iji mepụta ihe dị elu Cerium Carbonate.

Isi Atụmatụ:

Ịdị ọcha dị elu:Cerium Carbonate enweghị ihe ruru unyi sitere na ihe ndị dị n'ụwa dị ụkọ (dịka iron, calcium, sodium), ihe ruru unyi dị n'ime ya dịkwa obere.

Ezi mgbaze:Cerium Carbonate nwere ike ịgbaze ngwa ngwa n'ime mmiri na asịd siri ike.

Nkwekọ: Njikwa ogbe siri ike na mmepụta nkeCerium Carbonate na-eme ka mma kwụsiri ike maka mmepụta nnukwu ụlọ ọrụ mmepụta ihe.

Ihe ndị na-akpali mmepụta kemịkalụ: Cerium carbonate bụ ihe dị mkpa maka ihe ndị na-akpali mmepụta fluid catalytic cracking (FCC) nke e ji mee petrochemicals, na-eme ka mgbanwe hydrocarbon na iguzogide sulfur nke ihe na-akpali mmepụta dịkwuo mma. Ọ bụkwa ihe dị mkpa na ihe ndị na-akpali mmepụta mmepụta ihe na-eme ka ihe na-akpali mmepụta ihe na-eme ka ihe na-akpali mmepụta ihe na-eme ka ihe na-akpali mmepụta ihe na-eme ka ihe na-akpali mmepụta ihe na-eme ka ihe na-egbochi ikuku oxygen sie ike.

Ihe na-ewepụ phosphorus maka ọdọ mmiri: Dabere na ihe ndị dị na kemịkalụ ya, cerium carbonate nwere ike iwepụ phosphate n'ime mmiri nke ọma site na mmiri ozuzo, nke na-enyere aka n'ịgwọ nsogbu nke eutrophication nke ahụ mmiri.

Batrị na ihe ndị e ji eme ka ike dị: Cerium carbonate, dị ka ihe dị mkpa dị ụkọ n'ụwa, na-arụ ọrụ na ihe e ji eme katode nke batrị nickel-metal hydride (NiMH) dị na ya, na-enye ezigbo nkwụsi ike okpomọkụ. Ọ bụkwa otu n'ime ihe ndị bụ isi e ji eme ihe maka ịkwadebe sel mmanụ siri ike (SOFC) na batrị nchekwa ike.

Njikọta kemịkalụ: Cerium carbonate bụ ihe dị mkpa maka imepụta ihe ndị ọzọ dị na cerium (dịka cerium chloride, cerium oxide) na ihe ndị na-egbukepụ egbukepụ n'ụwa.
