| Research Abstract |
To open a new microscopic approach to gas-phase olefin polymerization process, DEM simulation, direct visual observation of particle growth process, development of a kinetic model based on the growth data and direct measurements of particle-particle interaction were aimed at. A DEM model was successfully developed to simulate the effect of particle mixing on non-isothermal temperature field in the polymerization reactor. Experimentally, the particle growth process was made possible to observe visually in a microreactor. The particle growth data were successfully reproduced by the newly developed kinetic model. Parameters determined by the model fitting to the observed data are in reasonable range compared to the previously predicted values. Particle-particle interactions in terms of cohesion as well as heat transfer were observed by a particle interaction meter newly developed and by an IR camera, respectively. A pressurized particle interaction meter was designed and constructed. All of these achievements are original and nothing similar has yet reported by other investigators.
