As the world’s largest carbon disulfide production base, Baijin Group has unremittingly followed the way of independent research and technical innovation to requite the Country. From the traditional charcoal method at the start-up, to the carbocoal method developed in 2002, to the natural gas method implemented with encouraging results in 2004, and to today’s new-type technique whose R&D has absorbed huge investment, the Group has defended its expertise leadership in the industry with strength in innovation.
We now own most patents in the industry in China. ――
Baijin Group is the owner of 5 state-level invention patents for carbocoal manufacturing techniques. Our success in the research on replacing charcoal with coke is revolutionary in the world’s history of carbon disulfide production and development.
Besides, 6 patents in natural gas manufacturing technique are being officially processed. Technologies covered by these patents will further contribute to clean and environment-friendly production.
Research work on new-type technique has led to applications for another 3 patents which are being processed. Featuring a wide range of advantages such as low cost, reduced area occupation, low energy consumption, and easy access to raw material sources, the new technique has lifted restrictions related to raw material’s origin place, environment, and safety in carbon disulfide production and pushed forward the boundary of manufacturing techniques. Our achievements have raised the level of carbon disulfide production to an unreached height and are epoch-making milestones in the field. |
