applications of steam reforming catalyst carriers can be classified as lubricants, plasticizers, dispersants, surfactants (which have both dispersant and lubricating functions), etc. To meet the forming requirements, a combination of various organic materials is usually used. When choosing applications of steam reforming catalyst carriers, consider the following factors:

1. applications of steam reforming catalyst carriers are necessary to be wetted by powder. Good wetting can be achieved when the critical surface tension (yoc) or surface free energy (yos) of the powder is greater than that of applications of steam reforming catalyst carriers.

2. applications of steam reforming catalyst carriers undergo red bonding with powder (one-time bonding), meanwhile, Cohesion (secondary binding) is produced within applications of steam reforming catalyst carriers due to orientation, induction and dispersion effects. Although water can also fully wet the poplar material, it is volatile, has a small molecular weight and low cohesion, and is not a good application of steam reforming catalyst carriers. According to the order of cohesion of various organic materials, they can be arranged in terms of groups as follows: -CONH - > -CONH2 > -COOH > -OH > -NO2 > -COOC2H5 > -COOCH5 > -CHO > = CO > -CH3 > = CH2 > -CH2

3. applications of steam reforming catalyst carriers should have a moderate molecular weight. To achieve full wetting, it is hoped that the molecular weight is small but the cohesion is weak. As the molecular weight increases, the binding ability enhances. However, when the molecular weight is too large, the confining force is too strong and it is not easy to be wetted, and it is also prone to cause deformation of the green body. To facilitate the movement of the chain segments within the molecule, a plasticizer should be added at this time to make the applications of steam reforming catalyst carriers softer and easier to form while they are easy to wet.

4. To ensure product quality, it is also necessary to prevent impurities from applications of steam reforming catalyst carriers, raw materials and preparation processes from causing harmful defects in the product. In the preparation of raw materials, mechanical methods such as crushing and mixing are used in combination with applications of steam reforming catalyst carriers and dispersants to achieve dispersion with as little condensed particles as possible. applications of steam reforming catalyst carriers are affected by the type and molecular weight, the nature of the particle surface and the solubility of the solvent, etc. They are adsorbed on the particle surface of the raw material and prevent the coagulation of the powder raw material through stereostabilization effect. In the forming process, applications of steam reforming catalyst carriers give the raw material plasticity, have water retention function, and improve the strength and workability of the formed form. applications of steam reforming catalyst carriers should be heated during the degreasing process to decompose and volatilize as they hinder the sintering of ceramics. Therefore, organic materials that can be easily dispersed and removed and do not contain harmful inorganic salts and metal ions should be selected to ensure product quality.
