    摘要: The method and apparatus for startup control of a polyolefine polymerization reactor of the present invention determines an olefine feed rate based on a reaction amount set by the heat balance within the polyolefine polymerization reactor, a reaction balance amount calculated from its unreacted amount and dynamic compensation amount, and the olefine concentration within the polyolefine polymerization reactor. Due to this, model errors are reduced, and the practical application of feed-forward control is possible.
