Insights in supported rhenium carbide catalysts for hydroconversion of lignin-derived compounds

[EN] Rhenium supported over activated carbon (AC) was carburized under different temperatures (from 500 to 700 °C) under a mixture of H/CH (75/25). Resulting catalysts were characterized by Nsorption, CO chemisorption, temperature programed reduction (TPR), ammonia temperature programed desorption (...
