突破己内酰胺成套技术的“三道关卡”

Core Viewpoint - The transformative caprolactam technology developed by the Sinopec Petroleum and Chemical Research Institute has been recognized as internationally leading, addressing key challenges in the domestic caprolactam industry [1] Group 1: Industry Challenges - Caprolactam is a crucial monomer for nylon 6, widely used in various sectors, but its production is energy-intensive and environmentally harmful [2] - Historically, China relied on imports for caprolactam, leading to significant investments to establish domestic production, which faced high costs and pollution issues [2] - The domestic caprolactam industry faces three major barriers: low carbon atom utilization and high emissions in traditional cyclohexanone production, technological restrictions on hydrogen peroxide, and quality issues in high-end applications [2] Group 2: Technological Innovations - The research team has pioneered a new cyclohexanone production technology that improves carbon atom utilization from 80% to over 95% and reduces waste emissions by 90% [3] - A novel fluidized bed technology for hydrogen peroxide production has been developed, enhancing safety and efficiency [3] - Key technologies have been created to improve the intrinsic quality of caprolactam, enabling it to meet high-speed spinning requirements and reducing CO2 and waste emissions by 43% and 73% respectively [4] Group 3: Collaborative Development - The successful industrialization of the new caprolactam technology is attributed to a collaborative innovation mechanism involving multiple stakeholders, including Sinopec and various research institutions [5] - The new technology has led to the establishment of the world's largest and most advanced caprolactam production facility, achieving significant reductions in CO2 and pollutant emissions, as well as production costs [5] - In 2024, this transformative technology is set to be recognized as one of the 30 major engineering projects by the Chinese Academy of Engineering [5]
