The solid-liquid separation of ultra-fine particles, especially the efficient separation in solid-liquid heterogeneous systems, is extremely difficult. Conventional separation methods such as filtration and centrifugation are hard to apply in large-scale industrial production. Membrane separation technology is one of the high-tech fields that has developed rapidly in recent decades, and it is now widely used in industries such as pharmaceuticals, textiles, metallurgy, and food processing. The process involves using a selectively permeable membrane as the separation medium. When there is a pressure difference between the two sides of the membrane, the components on the feed side pass through the membrane selectively, thereby achieving complete separation. In membrane technology, ceramic membranes made from porous ceramic materials exhibit good chemical stability, resistance to acids, bases, and organic solvents; strong antimicrobial properties; high mechanical strength, allowing them to withstand pressures of several dozen atmospheres, and they can be regenerated through high-pressure backwashing. They are also resistant to high temperatures, capable of functioning at around 773 °C, with maximum operating temperatures reaching 1073–1273 °C ℃ ; It has advantages such as a narrow pore size distribution and high treatment efficiency. Ceramic membranes are widely used in industry for solid-liquid separation in micron and sub-micron systems. Titanium-silica molecular sieves are micron-scale catalysts; their production process is accompanied by a problem of catalyst loss. Meanwhile, in the new process for the oxime synthesis via ammonia oximation, there is an issue of catalyst retention during the heterogeneous reaction process. The use of ceramic membranes can effectively solve the solid-liquid separation problem associated with titanium-silica molecular sieves in production and application. The retention rate of ceramic membranes for titanium-silica molecular sieves can reach 99.9%. https://attach01.hcbbs.com/forum/202204/15/141845c7uz6bdaa8nk8d0f.jpg.thumb.jpg For more information, please contact Manager Chen at Nanjing Ti Jing Fluid Technology Co., Ltd
