PARTICLE GROWTH SIMULATION PROGRAM IN POLYOLEFIN POLYMERIZATION REACTION AND APPARATUS FOR PARTICLE GROWTH SIMULATION

摘要

PPROBLEM TO BE SOLVED: To provide a simulation program to enable the designing of the catalyst morphology and the optimization of the polymerization reaction conditions regarding the polyolefin polymerization reaction that uses a support type catalyst. PSOLUTION: This particle growth simulation program makes a computer function as an input/setting means which inputs the execution conditions and the initial conditions of the simulation and sets them to the corresponding parts of the expression of the monomer concentration on the catalyst surface in the primary particle, the expression of the monomer concentration in a predetermined radius in the secondary particle, the expression of the temperature in the secondary particle and the processing procedure seeking solutions based on these expressions, which all the program provides; as a concentration/temperature calculation means which calculates, based on these, the monomer concentration on the catalyst surface in the primary particle, the monomer concentration in the predetermined radius in the secondary particle, and the temperature in the secondary particle as the solutions; as a concentration/temperature storing means which stores the solutions and the intermediate date calculated in the processing procedure of determining the solutions; as a particle growth information calculation means which reads these and at least calculates the porosity distribution and the particle strength/stress; and as a growth information storing means which stores these.
