从化学反应中的能量变化出发,通过相关化学反应的反应热计算得知:1 mol双氧水(H_2O_2)氧化1 mol硫化氢(H_2S)所释放的化学反应热,能够将原油中0.96 kg的癸烷从25℃(常温),加热至205℃(引燃温度),从而能形成2010年大连“7·16”爆炸火灾事故的点火源。事发原油管道中输入并储存了大量的H2O2(88 m~3),客观上又为燃烧提供了充
Based on the energy change in the chemical reaction, the reaction heat calculated from the relevant chemical reaction shows that the chemical reaction heat released by 1 mol hydrogen peroxide (H 2 O 2) oxidizing 1 mol hydrogen sulfide (H 2 S) can remove 0.96 kg of decane From 25 ℃ (room temperature), heated to 205 ℃ (ignition temperature), which can form the 2010 Dalian “7. 16” explosion fire ignition source. Incident crude oil pipeline input and stored a large number of H2O2 (88 m ~ 3), objectively provides a charge for combustion
