Study On The Process Of Preparation Synthetic Gas By Partial Catalytic Oxidation Of Natural Gas Through Air

With the change of the energy structure of the world, the efficient exploitation of the natural gas have receive more attention ever since. Nowadays, the developments of the new craft and industrialization process are the hot research areas in natural gas chemical engineering. The indirect conversion method can transform the natural gas to the synthetic gas(CO₂+H₂), which is an important chemical engineering raw material and has broad application in industry. The synthetic gas can be used in a series of important chemical products, such as the synthetic liquid fuel, methanol and chemical fertilizer.Since the 90's of 20th century, the methane partial oxidization method can turn the strong endothermic reaction to mild exothermic reaction, and the reaction conversion rate (YOF) is high. The ratio of the H2/CO in the production is 2, so the method is suitable for the methanol industry and F-T synthesis. The reaction can be carried out at the biggest empty speed(1⁵)×10⁵h^-1, and this can contract gas production scale, lower the investment and reduce the production cost. The production can be enhanced more than hundredfold if the technique reformation is applied for the original manufactory equipment. Owing to the above-mentioned advantage, the partial oxidization method has gained more people's attention.In this paper, the research has been carried out on the preparation of the synthetic gas from natural gas by the partial oxidization of air catalysis. This method can enhance the economic performance for the production of the synthetic gas evidently, because the expensive investment on the air separate equipment and the rise of the cost of oxygen production is avoided. The reactor structure adopt the distribute apparatus, and this make the oxygen distribute along the catalyst bed radially, so the upper hotspot of the catalyst bed is removed and the reaction heat is used more effectively. The safety of the reaction systems is guaranteed because the natural gas and oxygen is input respectively, for the natural gas is input in axis direction, and the oxygen distribution is input gradually in radius direction.
