Composite Carbon Foams as an Alternative to the Conventional Biomass-Derived Activated Carbon in Catalytic Application

The suitability of a new type polyurethane-based composite carbon foam for several possible usages is evaluated and reported. A comparison the properties as-prepared foams was performed with widely available commercial biomass-derived activated carbon. Carbon were synthesized from polyurethane different graphite contents through one-step activation using CO2. In this work, catalyst moderately active surface (SBET = 554 m2/g), thermal conductivity 0.09 W/mK, minimum metal ion content 0.2 wt%, which can be recommended phosgene production. exhibited better stability, as there very little weight loss at temperatures below 500 °C, slower above °C (phosgene synthesis: 550–700 °C). Owing to good negligible metallic impurities, produced are best alternative conventional coconut-based used in gas
