点“塑”成金！中美研发黑科技 常温下垃圾塑料转化为汽油

Core Insights - Scientists from China and the United States have developed a one-step method to safely convert toxic mixed plastic waste into gasoline, achieving over 95% conversion efficiency at room temperature [1][2] - This new process requires less energy, fewer steps, and less equipment compared to traditional plastic-to-fuel conversion methods, making it scalable for industrial applications [1] - The final products of the conversion process include gasoline components, chemical raw materials, and hydrochloric acid, which can be utilized in various industries such as water treatment, metal processing, pharmaceuticals, food production, and the oil industry [1] Group 1 - The global cumulative plastic production has reached 100 billion tons, with a significant portion destined to become difficult-to-recycle waste [2] - PVC, which constitutes about 10% of global plastic production, requires dechlorination before traditional energy recovery methods to prevent the release of toxic compounds [2] - The new strategy proposed by researchers aims to upgrade waste PVC into chlorine-free fuel-grade hydrocarbons and hydrochloric acid through a single-stage process [2] Group 2 - The team tested the conversion efficiency of PVC mixtures and polyolefin waste, achieving a solid conversion efficiency of up to 96% at 80 degrees Celsius [3] - The process is suitable for handling mixed and contaminated PVC and polyolefin waste commonly found in real-world scenarios [3]
