A solid surface wettability determination method is disclosed. A liquid is sprayed on a surface of an object. A light beam is projected toward the surface, wherein the light beam is reflected by the liquid on the surface to generate a reflected light. The reflected light is received by an optical detector, and the optical detector outputs a determining signal related to a wettability of the surface according to the reflected light. A corresponding signal-angle relation is selected from a database according to type of the liquid and material of the object. The contact angle of the liquid on the surface is obtained by applying the determining signal to the corresponding signal-angle relation.

Solid surface wettability determination method

A surface wettability determination system includes a sprayer, a light emission device and an optical detector. The sprayer is provided to spray a liquid on a detected surface of a detected object. The light emission device is provided to emit a light beam toward the detected surface. The light beam is reflected by the liquid on the detected surface to generate a reflected light. The optical detector is provided to receive the reflected light and output a determining signal, and the determining signal is related to a wettability of the detected surface.

A drying apparatus includes a gas flow channel, a first hollow fiber module, a second hollow fiber module, a gas driver and a control unit. The gas flow channel is used to accommodate an article and has a first terminal and a second terminal. The first and second hollow fiber modules are disposed at the first and second terminals respectively to adsorb water or to be electrified to desorb water. The gas driver disposed in a gas flow path of the gas flow channel drives the gas flowing into the gas flow channel through the first hollow fiber module and flowing out from the gas flow channel through the second hollow fiber module, or flowing into the gas flow channel through the second hollow fiber module and flowing out from the gas flow channel through the first hollow fiber module. The control unit provides power to the first and second hollow fiber modules and controls the gas driver.

Drying apparatus and drying method

A COadsorption and recovery system including an intake unit, a first purification/adsorption/regeneration unit, a second purification/adsorption/regeneration unit, a three-way valve switching unit, a vacuum drawing unit and an exhaust unit is provided. The first and second purification/adsorption/regeneration units have a hollow fiber bundle impurity adsorption column, a hollow fiber bundle COadsorption column and two heating devices. One set of adsorption columns performs purification and adsorption procedures to the inlet gas in a normal or high pressure condition, and the other set of adsorption columns performs desorption and regeneration procedures in a high temperature condition when the adsorption columns are heated by the heating devices. The three-way valve switching unit exchanges the purification and adsorption procedures with the regeneration procedure to the first and second units. The vacuum drawing unit draws COdesorbed from the COadsorption columns alternatively. The exhaust unit drains a purified product gas out.

Provided is a dehumidification system including an air directing device and an adsorbent hollow fiber module. The air directing device is used for conveying air. The adsorbent hollow fiber module can adsorb the moisture in the air as the air passes through the adsorbent hollow fiber module. The adsorbent hollow fiber module includes at least one adsorbent hollow fiber. The adsorbent hollow fiber has a tubular body having a first end and a second end and a channel disposed in the tubular body and extending from the first end to the second end.

Dehumidification system

A hollow fiber adsorbent compressed dry air system including an intake unit, a first adsorption/regeneration unit, a second adsorption/regeneration unit, a switch unit and an exhaust unit is disclosed. The first adsorption/regeneration unit has a hollow fiber adsorbent housing and a heating device disposed in the surrounding of the adsorbent housing. The second adsorption/regeneration unit has another hollow fiber adsorbent housing and another heating device disposed in the surrounding of the another adsorbent housing. One of the hollow fiber adsorbent housings performs drying procedure to the compressed air in the room temperature, and the other hollow fiber adsorbent housing, when heated by the heating device thereof, performs a desorption regeneration procedure in a high temperature condition. The switch unit alternately switches the drying procedure and the desorption regeneration procedure to the first adsorption/regeneration unit and the second adsorption/regeneration unit. The exhaust unit outputs dried product air.

The instant disclosure relates to a preparation method of ethanol reforming catalyst, comprising the following steps. The first step is mixing a first metal precursor, a second metal precursor, and a third metal precursor with an organic medium to form a mixture. The next step is adding a surfactant to the mixture, and then allowing resting for 3 to 7 days to form a colloidal gel. The next step is calcining the colloidal gel for 1 to 5 hours in a first temperature region of 350&#xb0; C. to 550&#xb0; C., and then calcining the colloidal gel for 1 to 5 hours in a second temperature region of 800&#xb0; C. to 1000&#xb0; C. to form an ethanol reforming catalyst. The instant disclosure further provides an ethanol reforming catalyst composition.
