LayCu0.4Fe0.6O3 perovskite oxides: synthesis, characterization and catalytic reactivity in the fischer-tropsch synthesis

The current natural gas production of 52 Mm3 d-1 and the large projects for its expansion has been setting new boundaries for the Brazilian industry of oil and gas. So far, one of the biggest challenges regards the logistics for gas transportation from offshore fields. Therefore, the transformation...

description The current natural gas production of 52 Mm3 d-1 and the large projects for its expansion has been setting new boundaries for the Brazilian industry of oil and gas.
