Compared with the traditional clay bleaching, it no need acid or alkali washing, heating or others complex processions,
the silica gel can bleach the oil directly without any operations, very easy and fast.
The silica gel can not only decolor, but also can lower the sulfur and acid content, reduce the impurities and residues,
adsorb the water. The final oil qulity will be good with light and clear color.
After processing, the oil quality can meet the national fuel standard (GB/T6540-86),
and the long-term storage does not change color and does not deteriorate.
Good stability, greatly saving investment, shortening process and time.
The silica gel have 4 sizes for diesel oil and gasoline oil decolor,
<0.3mm, <0.5mm, 0.3-0.7mm and 0.5-1mm.
The smaller of the size, and the oil color would much more clear.
But normally the <0.5mm is the size used most to decolor the oil.
The following picture with 3 oil colors shows the color with <0.5mm silica gel.
The water color comes from the first 20% of the oil, and the second light yellow color
comes from the laste 80% of the oil. The quality of raw oil much better,
the silica gel can decolor more oil, the best can decolor about 200-400 tons oil with 1 ton silica gel.
Simple instruction about how the silica gel decolor the dar color oil.
