混合废塑料化学循环
Huicheng's original and innovative deep catalytic cracking technology for waste plastics,
We have successfully overcome the key technical challenges in the chemical recycling and reuse of waste plastics, achieving a revolutionary "one-step" process,
It can achieve high-value recycling of low-value waste plastics, eliminating white pollution;
It also holds high strategic significance in reducing China's dependence on foreign crude oil, decreasing carbon dioxide emissions, and empowering the implementation of the dual-carbon strategy,
It provides a revolutionary "Chinese solution" for global plastic pollution control!
The company's proprietary Catalytic Pyrolysis of Composite Plastic Waste (CPDCC) technology directly converts various types of low-value waste plastics into products such as Liquefied Plastic Cracking Gas (LPCG), Plastic Cracking Gas (PCG), and Plastic Cracking Light Oil (PCLO) in a "one-step process", achieving a yield exceeding 92%. This technology has overcome industry bottlenecks such as the difficulty of sorting waste plastics, low yields of target products, poor product quality, and the corrosive nature of hydrogen chloride. The overall process technology is a world first.
● Continuous and stable feeding is achieved through gas-solid two-phase differential pressure conveying technology, enabling the successful scaling up and large-scale implementation of industrial plants.
The contradiction between the cracking depth of liquid-phase macromolecular hydrocarbons and high-temperature carbonization in the traditional plastic chemical recycling process has been overcome through cross-phase cracking.
● The original design of a countercurrent bed reactor is adopted, providing a matched reaction activation energy for hydrocarbon cracking with different molecular weight gradients based on the reactor temperature gradient.
● Cross-phase deep cracking and high-temperature chlorine capture have overcome the challenge of hydrogen chloride corrosion resulting from PVC cracking.
