Description
Description
In order to meet the requirements of efficient utilization of petroleum resources and cleaning of oil products, hydrogenation technology has been widely used. Hydrogenation catalyst is the core of hydrogenation technology, which is used for γ The alumina carrier is usually made of the product after roasting and dehydration. The Low Silicon Macroporous Pseudo Boehmite has good mechanical strength and thermal stability. When the product is used as an adhesive, it is not only conducive to the formation of the carrier, but also affects the catalytic performance of the obtained catalyst. The product can also be used to prepare γ- Al2O3 coating. We have been engaged in this industry for many years and have a professional R&D team, so we are sure to provide you with the best quality products.
Features
