2022, Powder TechnologyCitation Excerpt :The direct synthesis approach simplifies the overall process operations as it removes the intermediate syngas production step, and thus can greatly reduce the capital and operating costs. The major direct synthesis processes of methane to chemical products include selective oxidation to methanol, formaldehyde (HCHO), ethylene and other olefins [47–53]. As the reactions of chemical looping direct chemical synthesis processes are exothermic, the system operations do not require an external heat source, and thus have flexible and easily applicable heat integration options.

2022, Catalysis TodayCitation Excerpt :Adsorbed oxygen species are considered as strong oxidizing agents for the total oxidation of n-butane [27,108]. Such considerations and the possibility of separately optimizing the operating conditions for reduction or reoxidation of the catalyst have led to the development of DuPont's circulating fluidized bed concept [27,172]. From the existence of this process, Sahakini et al. [169] concluded that the involvement of chemisorbed oxygen in the n-butane oxidation process can be excluded.
