Clay is often employed as a catalyst, but quartz impurities can decrease the catalytic efficiency. Fine particles of clay can be purified by flotation. We examined the cationic surfactant hexadecyltrimethylammonium bromide (HTAB), the anionic sodium

Pillared clays are interesting materials with applications in catalysis and adsorption processes. To obtain these materials, several preparation procedures are necessary and must be optimized to tune the final properties of the resulting pillared cla

Although ruthenium is a common promoter for cobalt-based Fischer-Tropsch synthesis (FTS) catalysts, the origin of Ru promotion and promoter concentration effects remains controversial. To gain a fundamental understanding of the Ru promotion effects,

The production of C8 linear diols from a furfural-acetone condensation product has been achieved for the first time using a non-noble metal based catalyst. In particular, SBA-15 supported Ni Cu bimetallic catalyst showed the best hydrogenating activi

A series of Co-Ru/TiO catalysts (10 wt% Co, 0.5 wt% Ru, nominal loadings) were prepared by impregnation of TiO-anatase supports synthesized with different specific surface areas (Ti-L: 53 m/g, Ti-M: 117 m/g, and Ti-H: 148 m/g) by tuning the condition

Pillared clays (PILCs) are interesting materials mostly due to their high basal spacing and surface area, which make them suitable for adsorption and catalysis applications, for example. However, the production of these materials on industrial scale

Pure anatase and rutile TiO samples were synthesized by thermal treatment of reverse microemulsions and applied as supports for preparing Ru-promoted Co catalysts (0.5 wt% Ru, 10 wt% Co). The catalysts were characterized by ICP-OES, XRD, Raman spectr
