Disclosed herein is an experiment apparatus for estimating ground deformation during gas hydrate recovery. The experiment apparatus may include: a high-pressure cell having a space in which a sample containing gas hydrate is stored; a recovery member inserted into the sample so as to recover the gas hydrate contained in the sample to the outside; and a transparent region formed at one or more parts facing the space of the high-pressure cell, such that the sample stored in the space is observed from outside.

Experiment apparatus for estimating ground deformation during gas hydrate recovery

The present invention relates to a catalyst used for producing dimethylether, a method of producing the same, and a method of producing dimethylether using the same. More particularly, the present invention relates to a catalyst used for producing dimethylether comprising a methanol synthesis catalyst produced by adding one or more promoters to a main catalyst comprised of a Cu&#x2014;Zn&#x2014;Al metal component and a dehydration catalyst formed by mixing Aluminum Phosphate (AlPO) with gamma alumina, a method of producing the same, and a method of producing dimethylether using the same, wherein a ratio of the main catalyst to the promoter in the methanol synthesis catalyst is in a range of 99/1 to 95/5, and a mixing ratio of the methanol synthesis catalyst to the dehydration catalyst is in a range of 60/40 to 70/30.

Method of producing a catalyst used for synthesizing dimethylether from a synthesis gas containing carbon dioxide

Disclosed herein is a process for the preparation of dimethylether from hydrocarbons, including tri-reforming a feedstock mixture comprised of hydrocarbons, carbon dioxide and water vapor in the presence of a tri-reforming catalyst, to prepare a syngas, which then undergoes gas-phase direct synthesis into dimethylether in one step in the presence of a hybrid catalyst. According to the process of this invention, three main processes among typical syngas preparation processes are simultaneously performed, and then, the syngas thus obtained is prepared into dimethylether through a direct reaction in one step, thereby decreasing the apparatus cost and operation cost. In addition, all of the carbon dioxide separated and recovered from the unreacted material and by-products may be reused as reaction material, thus decreasing the generation of carbon dioxide and reducing the material cost.
