촉매 내 황화 반응

2016-04-15View Original

Thread Content

회사에서는 내유황형 CoMo 촉매를 사용하고 있습니다. 반응식은 다음과 같습니다:
CoO + H2S → CoS + H2O, ΔH0298 = -13.4 KJ/mol
MoO3 + 2H2S + H2 → MoS2 + 3H2O, ΔH0298 = -48.1 KJ/mol
여러분, 유황화 전후의 Co와 Mo의 화학적 종류 변화에 대해 논의해 보세요. 특히 Co의 화학적 종류 변화가 꽤 큰 것 같습니다

CoO의 Co는 +2가이며, CoS의 Co도 +2가로, 전하가 변하지 않습니다. MoO3의 Mo는 +6가이고, MoS2의 Mo는 +4가입니다.
