DESCRIPTION:
BRIEF SUMMARY
TECHNICAL FIELD
The present invention relates to a gas reactor, and more particularly, relates to a gas reactor to effectively purify gas discharged from factories and automobiles and to crack or synthesize various types of gas. Further, the present invention relates to a method of gas reaction.
BACKGROUND ART
It is well known that harmful components contained in the exhaust gas discharged from factories and automobiles cause air pollution. Concerning countermeasures to prevent air pollution, large-scale countermeasures are taken to prevent air pollution caused by the exhaust gas discharged from factories. Further, various countermeasures are proposed such as a countermeasure to prevent air pollution caused by the exhaust gas discharged from automobiles. Examples of the effective countermeasures to purify the exhaust gas are a gas reactor in which a catalyst is used and a gas reactor in which plasma generated by electric discharge is used. In these gas reactors, the action of a catalyst and the action of plasma are separately used. Therefore, in some cases, these gas reactors can provide satisfactory effects to purify the exhaust gas, however, in other cases, it is not possible for these gas reactors to provide satisfactory effects when very severe requirements are imposed on the gas reactors.
In order to solve the above problems, there is proposed a gas purifying apparatus in which the action of a catalyst and the action of plasma are combined to enhance the effect of purifying gas, for example, a gas purifying apparatus is disclosed in Japanese Unexamined Patent Publication No. 6-262032. According to the technique disclosed in this unexamined patent publication, not only can the gas be purified by combining the action of a catalyst and the action of plasma but a gas reaction can also be conducted for other purposes. Concerning the gas reaction, it is relatively easy to conduct gas cracking, but it is relatively difficult to conduct gas synthesis. Accordingly, it is required to provide a gas reactor capable of conducting gas cracking or gas synthesis more effectively.
Further, Japanese Unexamined Patent Publication Nos. 6-262032 and 7-185266 disclose gas purifying apparatuses in which fins are attached to a rotational body. According to this technique, the action of a catalyst and the action of plasma are combined to enhance the effect of purifying gas. Further, when a turbulent flow is generated by the rotating fins in the gas to be treated, the performance of purifying the gas is improved. However, even this type gas purifying apparatus is not appropriate for cracking gas.
SUMMARY OF THE INVENTION
An object of the present invention is to provide a gas reactor capable of cracking and synthesizing various types of gas effectively.
The present invention is to provide a gas reactor comprising: a housing; a first member arranged in the housing; a second member arranged opposed to the first member so as to form a gap between the first member and the second member; a catalyst carried by at least one of the first member and the second member; a means for generating plasma in the gap between the first member and the second one; a first gas passage communicating from a first gas inlet provided in the housing to a gas outlet via the gap; and a second gas inlet provided in the housing for flowing gas to a position on the downstream side of the gap in the first gas passage.
In this gas reactor, when the first gas passes through the gap, it is reacted or activated by the action of plasma generated by the plasma generating means or the action of the catalyst. The second gas that has not passed through the gap is mixed with the activated first gas. Therefore, the first gas is more reacted with the second gas. In this way, decomposition or synthetic reaction of gas is effectively conducted.
It is preferable that the first member is rotatably arranged and the second member is stationarily arranged. Due to the foregoing arrangement, when the first gas passes through the gap, a turbulent flow is generated in the gas
