摘要 应用本征气体化合物分解动力学的改进模型对天然气水合物的成分分离情况进行预测,分析各种天然气水合物分解动力学及其分解率最大估值公式。研究认为,在相同的驱动梯度下,天然气水合物的分解速度相对更慢;用客体解吸驱动梯度和气水合物分解速率的上极限表示的水合物晶格熔解过程具有独立性,应用分子分解速率流标准化公式能得到不同化合物形式的分解速率常数。 This thesis tried to apply the improved intrinsic kinetics of gas decomposition model to estimate the essen- tial characteristics of natural gas compounds and deduce the maximum valuation formula of decomposition rate and kinetics of gas hydrate. From the results, the speed of natural gas hydrate decomposition is slower than in the re- spective dissociation process under the same driving gradient. In addition, the object desorption drive gradient is independent from hydrate lattice melting process showed by the upper limit of gas hydrate dissociation rate. And the decomposition rate constants of different compounds form can be obtained with the help of appropriate molecular de- composition rate normalization formula.
