Abstract

A dehydrogenation chemical reactor includes: a housing; a catalyst part made of a thermally conductive material and disposed in the housing, where the catalyst part has a panel shape, and a catalyst is coated on a surface of the catalyst part to separate hydrogen from an organic hydrogen carrier; a heat transfer pipe which is installed to contact the catalyst part, and conducts latent heat to the catalyst part while pressurized and saturated fluid is supplied therein; and an organic hydrogen carrier line which is connected to the housing to form a passage in which the organic hydrogen carrier is introduced into the housing, contacts the catalyst part to separate hydrogen, and then is discharged.

First claim

What is claimed is:

1. A dehydrogenation chemical reactor comprising:
a housing;
a catalyst part made of a thermally conductive material and disposed in the housing, wherein the catalyst part has a panel shape, and a catalyst is coated on a surface of the catalyst part and configured to separate hydrogen from an organic hydrogen carrier;
a heat transfer pipe installed to contact the catalyst part, and configured to conduct latent heat to the catalyst part while pressurized and saturated fluid is supplied therein; and
an organic hydrogen carrier line connected to the housing and configured to form a passage in which the organic hydrogen carrier is introduced into the housing, contacts the catalyst part to separate hydrogen, and then is discharged.

2. The dehydrogenation chemical reactor according to claim 1 ,
wherein the organic hydrogen carrier line includes:
an inlet through which the organic hydrogen carrier is introduced into the housing; and
an outlet through which the organic hydrogen carrier is discharged from the housing after hydrogen is separated, and
wherein the inlet is positioned higher than the outlet.

3. The dehydrogenation chemical reactor according to claim 1 ,
wherein a collecting part is provided at a top of the housing and configured to collect the hydrogen separated from the organic hydrogen carrier.

4. The dehydrogenation chemical reactor according to claim 1 ,
wherein the pressurized and saturated fluid flowing in the heat transfer pipe is water.

5. The dehydrogenation chemical reactor according to claim 1 ,
wherein:
the catalyst part includes a plurality of catalyst flat plates;
catalyst flat plates of the plurality of catalyst flat plates are respectively coated with a catalyst; and
the catalyst flat plates are stacked on one another at regular intervals.

6. The dehydrogenation chemical reactor according to claim 5 ,
wherein the organic hydrogen carrier is configured to contact the catalyst through a separation space between the catalyst flat plates to separate hydrogen.

7. The dehydrogenation chemical reactor according to claim 5 ,
wherein the heat transfer pipe is bent in a zigzag shape of consecutively penetrating the plurality of catalyst flat plates to conduct latent heat, and
wherein the catalyst flat plates are stacked in a direction in which the pressurized and saturated fluid flows inside the heat transfer pipe.

8. The dehydrogenation chemical reactor according to claim 7 ,
wherein:
the catalyst flat plates of the plurality of catalyst flat plates are horizontally disposed at regular intervals to be spaced apart from each other, and
the heat transfer pipe is configured to: extend horizontally and bent upward after consecutively penetrating lower portions of the catalyst flat plates, and extend horizontally after being bent reversely to consecutively penetrate the catalyst flat plates reversely.

9. The dehydrogenation chemical reactor according to claim 1 ,
wherein: the heat transfer pipe includes a plurality of first pipes and a plurality of second pipes, which are disposed at predetermined intervals;
the plurality of first pipes is disposed horizontally with respect to a bottom of the housing, the plurality of second pipes is disposed vertically with respect to the bottom of the housing; and
the heat transfer pipe is formed by repeatedly connecting first pipes of the plurality of first pipes to second pipes of the plurality of second pipes.

10. The dehydrogenation chemical reactor according to claim 1 ,
wherein an agitator is provided in the housing, and the agitator is configured to generate vortex in the organic hydrogen carrier for a smooth contact between the organic hydrogen carrier and the catalyst part.

11. The dehydrogenation chemical reactor according to claim 1 ,
wherein the organic hydrogen carrier is dodecahydro-9-ethylcarbazole.

12. The dehydrogenation chemical reactor according to claim 1 ,
wherein a temperature in the housing is maintained at 180° C. to 350° C.
