In-house-fabricated aluminum monoliths were washcoated with Co-Re/Al2O3 catalysts for Fischer-Tropsch synthesis using two alumina supports with different texture. On one hand, a commercial mesoporous alumina support was used as reference material. On the other hand, a meso-macroporous alumina was prepared in the laboratory. The macropores were expected to act as transport pores and facilitate diffusion...
The present work reports the preparation, characterization and testing of Ca/Ce oxides as heterogeneous catalysts for the transesterification of sunflower oil with methanol (methanolysis), both in powder and structured forms, to produce biodiesel. A series of Ca-based catalysts in powder form were prepared on four different supports (commercial Al2O3, SiO2 and CeO2, along with in-house prepared CeO...
This paper reports developments in adapting a catalytic test unit (PID-Micromeritics Microactivity Reference) for testing microchannel cross-flow blocks during Fischer–Tropsch Synthesis (FTS). The unit was equipped with an additional cooling line with water pressurized to prevent boiling at the reaction temperature. A container in the water line partially filled with air was necessary in order to...
