Separating hydrogen technology from gas mixture by forming hydrate and its relative dynamics

The hydrate gas separating technology was defined according to the different conditions forming the hydrate from gas with different moleculars. A new method for separating or purifying hydrogen from gas mixture is proposed. A set of hydrate gas separating devices were set up for this purpose. The mixture of methane and hydrogen, and the mixture of dioxide carbon and hydrogen were selected as gas samples for separating experiment. The results confirm that the hydrate gas separating technology is feasible for hydrogen separation and purification. The vapor/liquid ratio of feed seriously influences the reaction speed. The calculation of the experimental data using the simplified Englezos Skovborg model shows that the coefficent parameter k is not a constant, but it is related with some special factors, such as gas content in the feed.
