The present invention aims at providing a method for producing a high-concentration alcohol from a water-alcohol mixture, in which the overall process is efficient and the present invention relates to a production method of a high-concentration alcohol, including a water adsorption step of adsorbing water of a water-alcohol mixture on an adsorption column to obtain a first concentrated alcohol, a water desorption step of introducing an alcohol to obtain a hydrous alcohol, and a membrane separation step of introducing the hydrous alcohol into a membrane separation unit provided with a membrane composite containing zeolite having an SiO/AlOmolar ratio of 5 to 15 to obtain a second concentrated alcohol.

Method for producing high-concentration alcohol

The present invention aims to improve the production capacity of alcohol in a method of producing high concentration alcohol using a distillation column and an adsorption-desorption column. The method is a method of producing high concentration alcohol by dehydration of a water-alcohol mixture, including: a distillation step of introducing a water-alcohol mixture into a distillation column to obtain crude alcohol; and an adsorption-desorption step of introducing a part of the crude alcohol into an adsorption-desorption column to obtain high concentration alcohol; wherein a further part of the crude alcohol is introduced into a dehydration apparatus to obtain high concentration alcohol.

The present invention relates to a dehumidification and humidification apparatus for vehicles using an adsorbent which is capable of feeding a dehumidified air for preventing fogging of window glass and a humidified air for improvement in comfortableness, and is simplified in construction thereof and reduced in size thereof. The dehumidification and humidification apparatus for vehicles according to the present invention comprises a casing (), and a blower (), an adsorbent module () and an air passage switching device () which are accommodated in the casing. The adsorbent module () comprises a Peltier element (), and a first adsorption component () and a second adsorption component () which are directly disposed on the respective surfaces of the Peltier element, and the air passage switching device () is arranged such that the air passing through the first adsorption component () and the air passing through the second adsorption component () are each turned toward either a first blowoff port () or a second blowoff port (), and turning directions of the respective airs are switchable therebetween. An electric current flowing through the Peltier element () in the adsorbent module () is reversed to switch operations of the Peltier element between a heat-absorbing portion and a radiating portion, and switch the turning directions of the respective airs in the air passage switching device ().

Dehumidification and humidification apparatus for vehicles

In a dehumidification/humidification device, a blower and an adsorbent module are contained in a casing. In other embodiment, the blower, the adsorbent module, and a flow passage-changing device are contained in the casing. The adsorbent module includes an adsorbing element formed by carrying an adsorbent on a permeable element and a heater directly disposed on the adsorbing element. The state of the electrification of the heater is changed and an air-blowing direction or a flow passage is changed, whereby a dehumidified air is discharged from a first suction/discharge port (or discharge port), and a humidified air is discharged from a second suction/discharge port (or discharge port).

Dehumidification/humidification device for vehicle

An adsorption heat pump is provided in which water vapor can be efficiently adsorbed and desorbed using a heat source having a lower temperature than ones heretofore in use because the pump employs an adsorbent which has a large difference in water adsorption amount in adsorption/desorption and can be regenerated (release the adsorbate) at a low temperature. The invention provides an adsorption heat pump which comprises an adsorbate, an adsorption/desorption part having an adsorbent for adsorbate adsorption/desorption, a vaporization part for adsorbate vaporization which has been connected to the adsorption/desorption part, and a condensation part for adsorbate condensation which has been connected to the adsorption/desorption part, wherein the adsorbent, when examined at 25&#xb0; C., gives a water vapor adsorption isotherm which, in the relative vapor pressure range of from 0.05 to 0.30, has a relative vapor pressure region in which a change in relative vapor pressure of 0.15 results in a change in water adsorption amount of 0.18 g/g or larger.
