DARCO BG 1 is a specialty activated carbon, developed for removing hydrogen sulfide
from biogas streams. DARCO BG 1 is produced by steam activation at high
temperature using a proprietary process, which does not involve the use of any
impregnant. As a result, the risk of bed fires due to exothermic reactions is greatly
reduced. DARCO BG 1 is produced as a 4×10 mesh granular carbon to provide a
low-pressure drop in gas phase applications, making it suitable for use in the
adsorption equipment at many of the existing biogas installations.
