实验测定了甲烷笼形水合物在d-（+）-葡萄糖水溶液中的H-Lw-V三相平衡条件。通过等温压力搜索法生成的平衡曲线的系统含有（10至30）重量%的葡萄糖在（275.15和281.25）K之间的温度和压力范围从（3.4至8.0）MPa。实验结果表明，含葡萄糖体系对甲烷水合物平衡条件表现出相当大的抑制作用，因为在给定温度下，这些体系的相平衡条件比纯水体系的相平衡条件向更高的压力移动。还发现，抑制程度与葡萄糖添加剂的浓度相关地增加，并且30wt%葡萄糖溶液的抑制上级低浓度的甲醇和等浓度的硫酸镁。
The three-phase hydrate–liquid–vapor (H–Lw–V) equilibrium conditions of the methane clathrate hydrate in aqueous solutions of d-(+)-glucose were experimentally determined. Equilibrium curves were generated via an isothermal pressure-search method for systems containing (10 to 30) wt % glucose at temperatures between (275.15 and 281.25) K and with pressures ranging from (3.4 to 8.0) MPa. Experimental results show that glucose-containing systems exhibit a considerable inhibiting effect on methane hydrate equilibrium conditions, as the phase equilibria conditions for these systems are shifted to higher pressures than those for pure water systems at a given temperature. It was also found that the degree of inhibition increases in relation to the concentration of the glucose additive and that the inhibition of 30 wt % solutions of glucose is superior to low concentrations of methanol and to equal concentrations of magnesium sulfate.
