May 14, 2015. According to reports from Sinochem News, a reporter from China Chemical Industry News visited Hebei Qiming Chemical Technology Co., Ltd. on May 13 and saw that China’s first facility for the continuous catalytic hydrogenation of petroleum resin to produce hydrogenated resin was operating smoothly. Since the first batch of high-quality C9 hydrogenated petroleum resin products were produced in February this year, the facility has been operating stably for 3 months now. This has filled the gap in China’s industry related to C9 hydrogenated petroleum resin, as well as C5 and C9 hydrogenated copolymerized petroleum resins, and will help advance China’s petroleum resin industry toward higher levels of the value chain. 　　This device utilizes the technology for the catalytic hydrogenation of petroleum resins to produce hydrogenated resins, developed by Professor Liang Changhai’s team at Dalian University of Technology. Through industry-university-research collaborations involving Tianjin University, Hebei Qiming Chemical Technology Co., Ltd., and other institutions, the industrialization of continuous catalytic hydrogenation technology for petroleum resins has been achieved. 　　It is understood that the hydrogenation of petroleum resins aims to saturate the double bonds in the resins and remove residual halogen elements, thereby improving the color and thermal stability of the petroleum resins, and producing lighter-colored petroleum resins with broader applications. Hydrogenated petroleum resins come in various types such as C5 and C9. At present, the production of C5 hydrogenated petroleum resins in China is fairly good, but for C9 hydrogenated petroleum resins, which require more complex processes, stricter reaction conditions, and a wider range of applications, China’s production capacity is still very limited. 　　According to Professor Liang Changhai, the hydrogenation reaction of C9 hydrogenated petroleum resin is costly and involves a complex process, making large-scale production difficult. In the process of preparing hydrogenated petroleum resins, developing an efficient catalyst is crucial. 　　Since 2006, Professor Liang Changhai’s team has been dedicated to the research and development of catalyst technologies. Focusing on key technical challenges such as harsh reaction conditions, high levels of gum formation, and numerous impurities in the catalytic hydrogenation of C9 petroleum resins, they have gone through four stages: catalyst development and selection, catalyst performance evaluation, catalyst lifetime assessment, and pilot-scale testing. Through thousands of experiments and tens of thousands of hours of research effort, they have successfully developed highly active and poison-resistant hydrogenation catalysts as well as corresponding hydrogenation processes. By establishing this comprehensive design and evaluation system, Professor Liang Changhai’s team managed to achieve a bright, white, and transparent color for the resin samples produced through catalytic hydrogenation, thereby providing a solid theoretical foundation and technical basis for industrial application. 　　Subsequently, Professor Liang Changhai’s team collaborated with Tianjin University to establish an industrialization system and applied for invention patents. In January 2013, Hebei Qiming Chemical Technology Co., Ltd. officially launched the design plans for the industrial facility using this technology ； In August 2013, construction of the industrial facility began ； In February 2015, the facility was successfully put into operation.
