A novel process for the selective elimination of fatty acid compounds containing carbon-carbon double bonds in trans configuration from a substrate containing cis- and trans-isomers of said fatty acid compounds, by selective adsorption by a microporous zeolite material is disclosed. The pore size and shape of usable zeolite materials enable differentiation between cis- and trans-isomers of unsaturated fatty acid chains. The zeolite materials used have a selectivity ratio alphatrans / cis higher than 1.00; this ratio is defined based on the elution properties of cis and trans double bond containing fatty acid methylesters dissolved in n-hexane during a column chromatography experiment with the zeolite material as the stationary phase and n-hexane as the mobile phase.

The invention, belonging to the technical field of explosive preparation, particularly relates to an emulsion explosive prepared by using hydrogen storage materials. The explosive comprises an emulsion base and a sensitizing agent, wherein, the sensitizing agent is titanium hydride, the weight of the sensitizing agent accounts for 0.6-8 % of the total weight of the titanium hydride hydrogen storage emulsion explosive, and the purity of titanium hydride is no less than 95 %. During the detonation process, partial titanium hydride reacts with water in the emulsion base to release a little hydrogen, thus a certain foaming effect on the emulsion base is achieved, and the emulsion base is allowed to detonate, so that titanium hydride plays a role as the sensitizing agent. Simultaneously, the rest titanium hydride is subject to thermal decomposition under the effect of high temperature generated by the reaction between emulsion base and hydrogen bubbles to rapidly release hydrogen, and hydrogen continues participating the detonation reaction with the emulsion base to allow the output energy to contain the energy released by the emulsion base and titanium hydride together. The titanium hydride hydrogen storage emulsion explosive disclosed herein has the characteristics of low output explosion pressure, large impulse, long decay time, and high energy.
