Abstract

Zeolite blocks with 10% binder and without binder were formed using 3D printing technology. A polylactide template with the preset shape and structure of channels was printed on a 3D printer. The zeolite material was formed in the voids of this template. Finally, the template was burned out from the final block. Blocks with a binder were prepared by filling the template with a paste containing microcrystalline zeolite of MFI structural type. Blocks without binder were prepared by steam-assisted crystallization leading to the formation of zeolite nanocrystals in the H-form in the template channels. A relatively strong block consisting of MFI-type zeolite and reproducing the polymer template void volume was obtained.

使用 3D 打印技术形成块状沸石

摘要

使用 3D 打印技术形成具有 10% 粘合剂和不含粘合剂的沸石块。在 3D 打印机上打印具有预设形状和通道结构的聚乳酸模板。沸石材料在该模板的空隙中形成。最后，模板从最终块中被烧毁。通过用含有 MFI 结构类型的微晶沸石的糊剂填充模板来制备具有粘合剂的块。通过蒸汽辅助结晶制备不含粘合剂的块，导致在模板通道中形成 H 型沸石纳米晶体。获得了由 MFI 型沸石组成并再现聚合物模板空隙体积的相对坚固的嵌段。
