The accumulation of greenhouse gasses (CH and CO) results in an increase in the temperature of the atmosphere. The conversion of greenhouse gasses into chemicals and fuels with high added value benefits not only the environment but also energy development. A promising and well-studied process is the reforming of methane, where CH and CO are converted into syngas (CO and H). However, catalysts hinder the development of the process. In this paper, we investigate the conversion of CH and CO into syngas using a thermal conversion method. The catalysis performance was evaluated by reforming methane. Ni-based catalysts were prepared by different methods. All prepared catalysts were characterized (XRD, HRTEM et al.), and the process of reforming carbon dioxide-methane was carried out in a fixed bed reactor under atmospheric pressure and a high temperature. Ni(M) @CeO is one of the most popular options due to the role of CeO. The deposition of coke in Ni-based catalysts was investigated.
温室气体(CH和CO)的积累导致大气温度升高。将温室气体转化为具有高附加值的化学品和燃料不仅有利于环境,也有利于能源发展。一个有前景且经过充分研究的过程是甲烷重整,即CH和CO被转化为合成气(CO和H)。然而,催化剂阻碍了该过程的发展。在本文中,我们研究了使用热转化方法将CH和CO转化为合成气。通过甲烷重整评估催化性能。采用不同方法制备了镍基催化剂。对所有制备的催化剂进行了表征(XRD、HRTEM等),并在常压和高温下于固定床反应器中进行了二氧化碳-甲烷重整过程。由于CeO的作用,Ni(M)@CeO是最受欢迎的选择之一。研究了镍基催化剂中焦炭的沉积情况。
