摘要
常温下铂催化氢氧复合是学术界非常熟悉的领域,但焦点一直集中于电池、燃料等领域。重水除氚需要进行大量的常温氢氧复合,该过程是在滴流床反应器中进行的气–气反应,而关于滴流床反应器的研究绝大部分是关于气–液反应的。常温氢氧复合由于缺乏可借鉴的经验,仍未得到深入研究。在Pt-SDB催化剂的制备得到一定研究结果的基础上,本文研究了不同粒径Pt-SDB对常温氢氧复合过程的影响,并推断出Pt与SDB之间的通过狭缝能够更好地相互作用,达到更好的催化效果。
Hydrogen-oxygen recombination catalyzed by platinum at ambient temperature is a field which is familiar to academia, but the focus has always been on battery, fuel and other fields. The heavy water detritiation requires a large amount of ambient-temperature hydrogen-oxygen recombination, which is a gas-gas reaction carried out in a trickle bed reactor, but most of the research on trickle bed reactors is about gas-liquid reactions. Due to the lack of experience which can be referenced, ambient-temperature hydrogen-oxygen recombination has not been studied further. Based on the study result of the Pt-SDB catalyst preparation, this paper studies the effect of Pt-SDB with different particle sizes on the hydrogen-oxygen recombination process at ambient temperature, and it is inferred that the slit between Pt and SDB can better interact with each other to achieve better catalytic effect.
