Pyrogenic Carbonaceous Materials – Specification and classes for material use – Part 1: General requirements
Abstract
This document specifies the permitted starting materials for the production of pyrogenic carbon materials for material use in various application areas, the specifications and the analytical methods to be used. The material applications of the materials include, for example, direct carbon storage, applications with long-term carbon storage and short-term material uses. NOTE 1 Pyrogenic carbons are typically produced by pyrolysis or gasification under conditions of near-complete exclusion of oxygen and typically at temperatures above 450 °C. NOTE 2 Torrefaction is the mild thermal pretreatment of biomass at temperatures typically ranging from 200 °C to 300 °C. NOTE 3 Pyrogenic carbons as defined by this standard may also be formed as a byproduct of hydrogen production, specifically when biomethane is used as the feedstock. NOTE 4 Maximum permissible contents may be defined in classification standards of the DIN 4883 series for individual application areas. Primary biomass as well as biogenic residues and by-products, which can be of plant, animal or microbial origin, can be used as starting materials. These source materials can contain organic, including fossil, and/or inorganic contaminants or impurities. Maximum permissible contents are defined for the individual areas of application. This document does not apply to fossil carbons or carbonized biomass such as peat. Substances from the hydrothermal conversion or torrefaction of biomass are also not within the scope of this standard due to the excessively high H/Corg ratios of > 0,7 of these materials.
