Kinetic and Thermodynamic Effects in the Preparation of Carbon Materials on Their Yield and Polymorphism
摘要
According to the theory of systems with chaos of chemical composition, the quantitative composition, consisting of a set of allotropic modifications of solid carbon products obtained by high-temperature synthesis such as graphene, carbon nanotubes, and amorphous forms of carbon with varying degrees of anisotropy, is due to self-replication and growth-specific entropy of the diversity of components in these processes. The number of carbon species formed in industrial thermolysis processes is primarily a function of the mean energy of the intermolecular interactions and rheology of the raw materials in a viscous state. In this work, we found patterns relating the activation energy of viscous flow to the coking of multicomponent hydrocarbon systems enabling prediction of the yield of carbon in industrial synthesis processes.
