一种钴基催化剂及其制备方法和应用
摘要：
一种钴基催化剂及其制备方法和应用是以活性半焦为载体，以钴盐为活性物质前驱体。活性物质前驱体的担载方式采用浸渍法，浸渍量控制在5-15％范围内。催化剂制备方法包括浸渍、干燥、焙烧和还原。所制备的钴基催化剂应用是在反应器中进行，其原料气比例CH4/CO2在1∶4～4∶1范围内，反应温度控制在600-900℃，空速为500-5000h-1，气体压力为常压至10Mp之间。在钴基催化剂的催化作用下原料气中CH4和CO2的转化率保持在90％以上。
摘要（英）：

The invention discloses a cobalt-based catalyst and a preparation method and application thereof. Active carbocoal is used as a carrier, and cobalt salt is used as an active substance precursor. The carrying mode of the active substance precursor is a soaking method, and the soaking amount is controlled in a range of 5 to 15 percent. The preparation method for the catalyst comprises soaking, drying, baking and reduction. The prepared cobalt-based catalyst is applied to a reactor, the raw material gas ratio CH4/CO2 is 1:4-4:1, the reaction temperature is controlled to between 600 and 900 DEG C, the air speed is 500 to 5,000/h, and the gas pressure is normal pressure to 10Mp. The conversion rates of CH4 and CO2 in the raw material gas are kept over 90 percent under the catalytic action of the cobalt-based catalyst.
