China Petroleum high performance hydrogen production catalyst research and dev

June 18, high activity of CO shift catalysts for hydrogen production process conditions of and 1000 hours stability evaluation test, in Daqing Chemical Research Center of Research Institute of petroleum and petrochemicals success, catalyst of the technical indicators are to meet the requirements of indicators.

This indicates that the catalyst for hydrogen production from high activity carbon monoxide shift has made substantial progress in the experimental study. China Petroleum (7.99, -0.11, - 1.36%) high performance catalysts for hydrogen production from R & D to step on to a new level, for petrochemical enterprises to develop high-end high added value products catalyst for hydrogen production from provides powerful technical support and guarantee.

Refinery hydrogen mainly used as gasoline and diesel hydrogenation to improve the quality of oil, especially with the continuous improvement of heavy crude oil, poor quality trend intensified and the quality of oil, proportion of gasoline and diesel hydrotreating will continue to improve. Increasing hydrogen production and reducing energy consumption are the main problems in China's oil production. At present, the steam reforming process is the main technology of hydrogen production from refinery. The core of this technology is the catalyst. Therefore, it is imperative to carry out the research on the new technology of hydrogen production and high performance hydrogen production catalyst.

For big steel-making plant hydrogen production catalyst development and hydrogen production core technology research and development efforts, China Petroleum start carbon chemical technology research and development projects. Sinopec Daqing chemical research center and Fuzhou University, the development of low temperature and high activity, high stability of carbon monoxide shift catalyst for hydrogen production, and the establishment of a catalyst evaluation unit. Through the device inspected the reaction temperature, pressure, space velocity, steam gas ratio on the catalyst activity and stability, optimization of the process conditions and catalyst 1000 hours stability evaluation test.

The results of the experiment indicated that the high activity of CO shift catalysts for hydrogen production with refinery hydrogen production in a wide range of adaptability to raw materials, low temperature, high activity and high stability characteristics and technical indexes reach similar catalysts in the domestic leading level. Compared with the traditional copper zinc aluminum catalyst, the catalyst can improve the activity and stability of the catalyst by introducing a new type of auxiliary agent, and has the advantages of high concentration of carbon monoxide conversion needs and so on. This study provides basic data for the preparation and industrial application of catalyst amplification, and determines the optimum process conditions for the catalyst.
Using high activity carbon monoxide shift catalyst can increase the conversion rate of carbon monoxide, reduce the amount of catalyst used, increase the yield of hydrogen, increase the amount of heat recovery and save energy consumption. The catalyst will effectively promote the development of China petroleum refinery hydrogen production technology development and application of, will China's condition is complex synthetic ammonia plant and hydrogen plant to reduce energy consumption, improve economic efficiency, the refinery hydrogen plant expansion of production is of great significance.
