Sinopec develops novel structured zeolite

The research group headed by Prof. Weimin Yang from Sinopec Shanghai Research Institute of Petrochemical Technology (Sinopec SRIPT) has successfully synthesized a novel structured zeolite SCM-14 (SINOPEC Composite Material 14). Its framework type code SOR has been approved by the Structure Commission of International Zeolite Association (IZA-SC) on May 15^th, 2018.

As an important class of functional material, zeolite is widely used in chemical processes like ion exchange, adsorption/separation, and catalysis. The innovation and industrialization of novel zeolites have led to the leaping development of many chemical technologies.

Currently, Yang’s group has developed a series of SCM-n (n=1~21) zeolites named after SINOPEC based on more than 2000 experiments carried out in the last 5 years. SCM-14, one of the SCM-n zeolite, is a new and thermally stable zeolite possessing a unique 3D framework structure of 12-, 8- and 8-ring channel system. Its structure was determined by a combination of electron diffraction and powder X-ray diffraction through close cooperation between Yang’s group and Dr. Junliang Sun, a research fellow from Stockholm University/Peking University. The zeolite SCM-14 shows application potentials in catalysis and adsorption.

The group from SRIPT is now carrying out an in-depth study on the adsorption and catalysis properties of SCM-14, hoping to accelerate the pace of industrialization of SCM-14 in a bid to innovate a new petrochemical technology in the coming future.
