| With the shortage of world raw oil, it is very important for related researchers to explore the way how to exploit plentiful methane around world. In 1982, Kelter and Bhasin discovered the Oxidation Couple Reaction of Methane (OCM). Unlike the other conversion ways of methane, the conversion way of OCM has not only single product and simple separation process as well as low cost of engineering investment, but also that ethane of product is the original material for whole chemical industry with the new conversion way of natural gas. To industrialize the OCM, researchers have gained many achievements in some aspects such as catalytic mechanism, catalyst component, catalytic process, catalytic reactor and catalyst characterization and so on, but the yield and steady of catalyst have still not recorded heavily. Noticeably, the preparation of catalyst can obviously affect catalyst effect. So this paper will take the preparation of catalyst as the starting point to explore the way to develop the catalyst effect.For the complication of OCM process, two-component catalyst hardly meets the need of development of catalyst yield. So it is necessary for the development of multi-component oxidative catalyst. This chemical lab has made research in the subject for long time and has succeeded in designing a six-component OCM catalyst. For example, Huang Kai in the Chemical Engineering Department in Zhejiang University had optimized a six-component catalyst with artificial neural network aided-design. And the six-component shows high catalytic activity when GHSV was 33313 ml-g"1-hr"1, the proportion CH4 to O2 was 3 to 1 at 1069K. This paper will prepare and test 3 groups of catalyst on the base of component of this catalyst and test process.This paper will research 4 kinds of preparation including Dipping, Mechanic Mixing, Co-precipitation and Homogeneous Precipitation, especially for Mechanic Mixing and Dipping. For many affective factors of every preparation, this paper willunited 3 trial design methods to lay out the trial schedule of catalyst and design 3 groups of catalyst preparation schedule to pick out secondary factor and research main factor in detail. In Basic Contrast Trial Group 1, 59 catalyst samples were prepared firstly to simply research every factor from 4 kinds of preparations. And then, with the analyses method of range, it is induced that each of Dipping, Mechanic Mixing and Co-precipitation has 3 main factors and Homogeneous Precipitation has a main factor. In the Orthogonal Trial Group 2, 27 catalyst samples were prepared firstly to properly research every main factor from 3 preparations. And then, with the Analyses Method of Destination, it can be confirmed every most important factor from Dipping, Mechanic Mixing and Co-precipitation. In the Single Factor Trial Group 3,21 catalyst samples were prepared firstly to research every most important factor from 4 preparations in detail. And then, with the Analyses Method of Regression, the following results may be induced. For Dipping, with the improvement of dipping temperature, catalyst yield will rise in beginning and then fall down, and it can get on peak value when dipping temperature is 47.38℃; for Mechanic mixing, with the improvement of decomposition temperature, catalyst yield will rise in beginning and then fall down, and it can get on highest point in the course when decomposition temperature is 547℃; for Co-precipitation, with the improvement of major solvent volume, catalyst yield will fall down sharply in beginning and then set down slightly, so it is rational for major solvent volume to be 10ml on consideration of dissolution request and experiment feasibility in practice; for Homogeneous Precipitation, with the increase of urea quantity, catalyst yield will rise quickly in beginning and then move up slightly, so it is reasonable for urea quantity to be between 1.8g and 2.0g on consideration of separation inconvenience and factual effect.From 3 groups of test results, it may be shown that Dipping and Mechanic Mixing are better effective methods in c...
