What is the carrier of the silica catalyst?

The main advantage is that the chemical properties are relatively stable. It is an acidic oxide and does not react with ordinary acids. It does not interact with halogens, hydrogen halides, sulfuric acid, nitric acid, and perchloric acid other than fluorine and hydrogen fluoride (except for hot concentrated phosphoric acid). If it reacts with the catalyst, it will cause the catalyst to be poisoned. A phenomenon in which the activity and selectivity of the catalyst are significantly reduced or lost due to the trace impurities contained in the reaction raw materials. The essence of the poisoning phenomenon is a certain chemical action of trace impurities and the active center of the catalyst to form inactive species.
Secondly, silica has good wear resistance, stable chemical properties, and high melting point. For this reason, using it as the main mineral phase material as the catalyst carrier, its performance is stable.
In addition, the treated silicon dioxide has a high specific surface area and strong adsorption, which can increase the catalytic efficiency of the catalyst!
In general, the silica carrier has great advantages in terms of catalytic efficiency, catalytic activity, solidity of catalyst loading, service life, and price!
Fumed silica (fumed white carbon black) is one of the extremely important high-tech ultrafine inorganic new materials. Because of its small particle size, it has a large specific surface area, strong surface adsorption, large surface energy, high chemical purity, and dispersion. Good performance, heat resistance, electrical resistance and other aspects have specific performance, with its superior stability, reinforcement, thickening and thixotropy, it is especially advantageous in the catalyst carrier.
