Synthesis of negative and near-zero thermal expansion powders with low degree of agglomeration is one of the major challenges in their applications. In this research, Y 2 W 3 O 12 was synthesized via two soft-chemical approaches, co-precipitation by

Four FCC catalysts were compared in a CREC Riser Simulator reactor using an aromatic Brazilian VGO feed aiming at maximum low aromatic middle distillate production. Differences in activity were compensated by changes in the contact time. The first ca

1D nanostructured sodium trititanate was synthesized by alkali hydrothermal treatment of TiO 2 anatase, coexisting with incompletely converted precursors like nanosheets and poorly crystalline aggregates. This product easily exchanged with Fe 3+ at r

A nanostructured protonated titanate, synthesized by alkaline hydrothermal treatment of TiO2, has been investigated as a precursor support for NiMo hydrotreating catalyst and compared to alumina and titania as reference carriers. Each of the three po
