The need for greener procedures is a fact to reduce residues, to decrease industrial costs, and to accomplish the environmental agreements. In an attempt to address this question, we propose the addition of a natural resource, Brazilian diatomite, to an MFI zeolite traditional synthesis. We have characterized the resulting product with different techniques, such as X-ray diffraction ...

The diatomite particle lengths ranged from 20 μm to 70 μm, with widths from 7 μm to 15 μm. The pores were approximately circular with diameters between 100 nm and 150 nm, spaced longitudinally from 100 nm to 150 nm, and transversely from 180 nm to 200 nm. Other diatomite particles had false ellipse-shaped pores (Fig. 3(b)). The diatomite ...

Raise Your Glass to Diatomite. By Esa Nummi 10.25.2016. If you enjoyed a beer during Oktoberfest, you might want to know you have mining to thank for that frosty brew. Diatomite is mined to produce diatomaceous earth, which is used to filter beer, wine, juice, and water. Diatomite is a soft, porous, silica-rich sedimentary rock.

The MCM-22 zeolite was produced using diatom as the green silica source through the vapor phase transport assisted-synthesis. This study shows that this process is essential as, in classical rotation conditions, only an amorphous material is produced. The diatomite-MCM-22 zeolite catalytic activity was tested in the degradation of low and high-density polyethylene as a probe reaction. The ...

The processing technology and application of diatomite. Diatomite is deposited 10,000 to 20,000 years after death to form diatomaceous earth. Diatomaceous earth is a kind of biogenic siliceous sedimentary rock, which is mainly composed of the remains of ancient diatoms. It is soft, loose, delicate, porous and light, and has adsorption properties.

Diatomite is a chalk-like, soft, friable, earthy, very fine-grained, siliceous sedimentary rock, usually light in color (white if pure, commonly buff to gray in situ, and rarely black). It is very finely porous, very low in density (floating on water at least until saturated), and essentially chemically inert in …
