Core Viewpoint - The company has successfully completed the third phase of long-term stable operation testing for its 200,000 tons/year mixed waste plastic resource utilization demonstration project, and it is currently entering an optimization and modification phase expected to last about one month [2]. Group 1: Project Progress - The 200,000 tons/year mixed waste plastic resource utilization demonstration project has met expected operational goals after completing three systematic testing phases [2]. - The project has undergone tests to verify process stability and optimize equipment operating parameters [2]. - The third phase included optimization experiments focusing on key process elements such as raw material adaptability, reaction temperature variations, oil and gas residence time and temperature, and catalyst formulation for product selectivity [2]. Group 2: Future Plans - The project is now entering a shutdown optimization modification phase, which is anticipated to take approximately one month [2]. - This phase aims to lay the groundwork for subsequent device calibration and efficient stable operation [2]. - The project is positioned to provide important demonstration experience for promoting the green and high-quality development of the waste plastic recycling economy [2].
