Abstract

Método para preparar carbón poroso que exhibe selectividad mejorada para aldehídos de bajo peso molecular, tal como formaldehído, y para cianuro de hidrógeno. El método comprende el paso de aplicar carbonato de magnesio al carbón antes de la policondensación y/o carbonización, de modo que el carbón poroso se impregna con carbonato de magnesio. El carbón es apropiado para usar en la filtración de humo.Method for preparing porous carbon that exhibits improved selectivity for low molecular weight aldehydes, such as formaldehyde, and for hydrogen cyanide. The method comprises the step of applying magnesium carbonate to the carbon before polycondensation and / or carbonization, so that the porous carbon is impregnated with magnesium carbonate. Coal is suitable for use in smoke filtration.
