Hainan University Professor Li Jianbao, Professor Ji Zhongli China University of Petroleum presided over the "863" project - preparation of large size of the ceramic high-temperature filter tube, a few days ago in Yixing, Jiangsu Province nonmetal Chemical Machinery Co., Ltd. successfully developed and applied to Liuzhou Chemical AG Shell Coal Gasification plant. So far, the device has been continuous and stable operation over a month, the filtration precision and filter the gas flow and other technical indicators have reached the company's production process.

    The high temperature and high pressure gas - solid phase separation of the ceramic membrane filter tube project is the use of pressurized coal gasification technology for carbon conversion and energy recovery refinery catalytic cracking unit is an important issue. At home and abroad in a pressurized coal gasification technology and refinery FCC unit is often used on filtration and separation method, the synthesis gas containing more ash particles into the high temperature and pressure filter to remove the ash particle separation, in order to increase pressure Purification of the pulverized coal gasification technology in the gas directly efficient use of FCCU flue gas temperature high-grade heat. Ceramic membrane filter tube is high temperature and pressure in the filter core component of our research in this area started late, used in high temperature and pressure in the filter ceramic membrane filter tube still need to rely on foreign imports.

    In Professor Li Jianbao led the "863" project group and Yixing, Jiangsu Province, non-metallic chemical Co., Ltd., after years of research, and finally overcome this problem. They developed a high-temperature filter tubes with high filtration precision, ventilation volume, easy to plug, easy to clean, low cost, etc., to fill the gap. This key technology breakthrough, not only to promote the localization process of Shell Coal Gasification plant, but also has great significance for the promotion of technological upgrading of filter materials industry to achieve industrial development of the filter material.

    With the development of pulverized coal gasification technology, coal liquefaction technology, and integrated gasification combined cycle power generation technology, high-temperature ceramic membrane filter tube in the field of coal chemical industry, petrochemical industry, metallurgical industry, thermal power generation and environmental protection have broad application prospects.
