of graphite substrate. The selection of coating includes the coating materials system and the preparation techniques. In addition, attention also should be paid to the anti-oxidation mechanism. SiC based... temperature to fill the cracks in the coating. And the oxides also can be used as a sealing material to prevent the infiltration of oxygen. The most common used ceramic coating systems are Si-based......

; 开放科学(资源服务)标识码(OSID) 文章编号:1672-7207(2021)01-0070-16 Advances in Fe-based chemical looping technology for CH4/CO2... in the same reactor and different reactors. Thermodynamic calculation results prove that Fe-based oxygen carriers are promising in the field of chemical looping CH4/CO2 conversion. Different supports......
technology has made it possible to produce structural ceramics materials with highly complex geometric shapes and interconnected pores. Simultaneously, the use of 3D-printing technology based on light curing... in Figure 4 [10]. The ceramic samples’ porosity using expoxy-based and water-based binders is about 60% and 70%, respectively. The advantage of this technology is to avoid the problem of powder......
based on hydrogen metallurgy[42] 1.3 富氢熔融还原炼铁技术研究 1995年,EDELSON[3]提出了采用H2熔融还原铁矿制备铁水的工艺,该工艺将铁矿原料和助熔剂从炉顶加入,从还原炉中上部,中下部分别通入O2和过量的H2,炉料下落过程中首先通过由过量H2与O2燃烧产生的火焰区被完全熔化,然后熔体通过还原区被H2还原,最后熔体在还原炉底部实现渣铁分离.从炉顶...应,还须解决热量平衡问题,以维持稳定的反应过程.
