Pyrolysis behaviors of coal-related model compounds catalyzed by pyrite
Pyrite Catalytic pyrolysis Coal-related model compounds Tetrahydronaphthalene
2023/6/19
The pyrolysis behaviors of coal-related model compounds (bibenzyl and benzyloxybenzene) were investigated on a fixed-bed reactor catalyzed by pyrite (main component is FeS2). The pyrolysis products we...
Continuous Model for Homopolymers
Homopolymer polymer the temperature parameters of spherical expansion stage
2015/9/28
We consider the model for the distribution of a long homopolymer in a potential field. The typical shape of the polymer depends on the temperature parameter.We show that at a critical value of the tem...
A solvable model for homopolymers and self-similarity near critical point
Gibbs measure homopolymer zero-range potential phase transition glob- ular phase diffusive phase
2015/9/28
We consider a model for the distribution of a long homopolymer with an at- tractive zero-range potential at the origin in R3 (polymer pinning and de-pinning). The distribution can be obtained as a lim...
Numerical Investigation of Subcooled Boiling in a Vertical Pipe Using a Bubble-Induced Turbulence Model
Subcooled boiling k− turbulence model bubbles
2009/10/12
A bubble-induced turbulence model is applied to subcooled boiling of water in a vertical pipe. The volume fractions, velocities, temperatures of water and steam and turbulence characteristics of the f...
A Population Balance Model for Disperse Systems： Particle Size Distribution in Suspension Polymerization
悬浮液聚合 种群平衡模型 分散体系
2009/4/28
On the basis of population balance a mathematical model is developed to describe the formation of polymer partlcle in styrene suspension polymerization. The characteristics of coalescence and breakage...
