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 proposethe addition of a natural resource, Brazilian diatomite, to an MFI zeolite traditional synthesis. We havecharacterized the resulting product with dierent techniques, such as X-ray diraction, microscopy,and gas sorption, and, afterwards, we evaluate the greenness of the process by the Green Star method.The results were promising: We obtained the desired topology in the form of small crystallitesaggregated and a pore diameter of 0.8 nm. In conclusion, the product has the necessary characteristicsfor an adsorption or catalytic future tests and escalation to industrial production.
