【正文】 液的存在，環(huán)戊烷和水的接觸面積增大，在同樣時間內(nèi)生成水合物的量增大，放出的熱量增多，溫升較大。 環(huán)戊烷存在時水合物生成過程中溫度隨時間的變化Fig. Temperature in hydrate formation experiments with cyclopentane 環(huán)戊烷乳化液存在時水合物生成過程中溫度隨時間的變化Fig. Temperature in hydrate formation experiments with cyclopentane emulsion 環(huán)戊烷及其乳化液對CO2水合分離性能的影響水合反應(yīng)達(dá)到平衡后，分別測得剩余氣相以及水合物相分解氣的組成。環(huán)戊烷未預(yù)先乳化的情況下，在進(jìn)料壓力范圍內(nèi)，水合物相CO2濃度隨壓力增大先增大后減小， MPa時取到極大值，相同的趨勢發(fā)生在環(huán)戊烷乳化液存在時()。，環(huán)戊烷乳化液存在時，水合物相中CO2濃度低于相同條件下未乳化的環(huán)戊烷存在條件下的水合物相中CO2濃度，原因可能是有環(huán)戊烷乳化液時，環(huán)戊烷和水的接觸面積增大，生成了環(huán)戊烷和水的水合物。 CO2/N2環(huán)戊烷與水生成水合物時氣相和水合物相組成Tab.
