Abstract :

The production of polyvinyl chloride (PVC) by acetylene method is quickly developing in the Xinjiang region; however, serious mercury pollution has been an obstacle to the survival and development of this technology. Therefore, the exploitation of a “non-mercury catalyst” is of great importance for acetylene hydrochlorination reaction. Previous investigation demonstrated that Au catalyst displayed excellent catalytic performance for acetylene hydrochlorination; however, Au catalyst was expensive and scarce. Therefore, a “non-mercury cata­lyst” with low cost and excellent catalytic performance is of great importance to produce PVC by the acetylene method. In this report, it is successful to develop a new series of carbon-nitrogen non-metallic catalysts for acetylene hydrochlorination. We enhance the catalytic activity and stability through the precise and controlla­ble design of large pores and defective structures with catalysts and novel regeneration methods and initially explore the structural modulation of high-density pyridinic-FeN4 based on carbon-nitrogen materials. A mer­cury-free acetylene hydrochlorination catalyst with low cost and high performance was obtained to provide a technical data basis for the clean production of acetylene polyvinyl chloride.conductivity. Acceptable transport efficiency and correlation coefficients (R2> 99 %) and a reproducibility of %3.15 (n=10) was obtained. This system was an applicable, simple and inexpensive low voltage bio-device comparable to the introduced systems such as capillary electrophoresis.
