Silica gel for oil refining
- Detail
- Parameters
B9R silica products are micronized synthetic amorphous silica. They are used for removing polar impurities, especially phospholipids and related metal ions, in the oil refining process, and can be used in combination with clays for bleaching, thus achieving the aim of color reduction. This can significantly reduce the total quantity of adsorbent used and enhance quality of the oil.
B9R silica products are characterized by the property data shown below. The properties are within the given range, along with manufacturing specifications.

Dry Loss at 105℃，% | 55-70 | 55-63 | 25-45 |
SiO2, (dry basis), % | ≥99 | ≥99 | ≥99 |
pH (5%w/w suspension) | 2.5-4.0 | 1.5-3.0 | 6.0-8.0 |
D50, μm | 16-25 | 16-25 | 16-25 |
• High degree of chemical purity
• Amorphous silica, without crystalline quartz species
• Safe to handle
• Low product loss during handling
• Massive internal particulate surface area
• Small quantity, highly efficient
• Reduced need of process wate
• No negative effects on oil chemistry
Optimum conditions for the use of B9R silica in the oil refining process are:
• Oil temperature is 70-100℃.
• B9R silica is added under stirring, and the recommend usage amount is 0.05-2.0%.
• The contact time between the B9R silica and the slightly moist oil 20-40 minutes.
• The polar contaminants can be adsorbed by B9R silica, and then can be removed through filtration.
