为解决氢气导致高真空多层绝热储罐夹层真空度下降和吸氢剂价格昂贵的问题,本文搭建了吸氢试验台,研究了廉价微热型吸氢剂CuO和CuO+C的吸氢性能;结果表明:C的加入使CuO吸氢活化温度下降了100℃,吸氢速率提高了26.2倍;测定了CuO+C的吸氢等温线,分析了多次吸氢过程,得知在低压时,吸氢产物对吸氢有促进作用,而在高压时,作用不明显;根据BDDT理论,该等温线属于第Ⅰ类吸附等温线,并用Langmuir等温式进行了拟合
In order to solve the problem that hydrogen can reduce the interlayer vacuum of high-vacuum multi-layer insulated storage tank and the expensive hydrogen-absorbing agent, a hydrogen absorption test bench was set up to study the hydrogen-absorbing properties of CuO and CuO + C The results showed that the addition of C decreased the activation temperature of CuO hydrogen absorption by 100 ℃ and the hydrogen absorption rate increased by 26.2 times. The hydrogen absorption isotherm of CuO + C was measured and the hydrogen absorption process was analyzed. , And the products of hydrogen absorption promoted the hydrogen absorption but not obvious at high pressure. According to the BDDT theory, the isotherms belong to the class Ⅰ adsorption isotherms and were fitted by the Langmuir isotherm
