摘要:
为了研究水合物的生成,在281.15 K,4 MPa条件下,将纳米颗粒氧化石墨烯(GO)与十二烷基硫酸钠(SDS)复配,研究在高压反应釜内不同复配质量分数的复合促进剂对CO2气体水合物生成特性的影响。结果表明,GO与SDS复配可以促进水合物的生成,大大缩短生成时间,降低平衡压力,增加耗气量,加快生成速率。其中,最佳复配质量分数为0.005% GO和0.2% SDS,与纯水和0.005% GO相比,在该复配体系中,生成时间降幅分别达69.7%和12.2%,相平衡压力降低了11.3%和3.0%,耗气量提高了11.24%和3.2%。分析认为,GO与SDS的复配是强化水合物生成的高效促进剂。
Abstract:
To study the formation of gas hydrate, the effects of different concentrations of graphene oxide(GO)nanoparticles and sodium dodecyl(SDS)on CO2 hydrate formation in a high pressure reactor at 281.15 K and 4 MPa were investigated. The results showed that the addition of GO and SDS can promote CO2 hydrate formation, shorten formation time significantly, reduce equilibrium pressure, increase the gas consumption and accelerate formation rate. The optimal concentration was 0.005% GO with 0.2% SDS, in which concentration the formation time was shortened by 69.7% and 11.2%, the equilibrium pressure was lowed by 11.3% and 3.0%, the gas consumption was increased by 11.24% and 3.2% respectively, compared with pure water and 0.005% SDS. By analyzing, GO and SDS is an effective promoter to enhance hydrate formation.
