using the coal–derived AC had the highest maximum power densities in MFCs (1620 ± 10 mW m –2) even though this AC had only average catalytic activity, measured by reduction onset potential (E. onset = 0.09 V), and selectivity, based on number of electrons transferred(n = 2.4). This coal–based AC also had the lowest specific surface area
PTFE membrane filters are among the most efficient industrial air filters. PTFE-coated filters are often used in dust collection systems to collect particulate matter from air streams in applications involving high temperatures and high particulate loads such as coal-fired power plants, cement production and steel foundries.7
coal for the production of coke (Ref. 5.2.). Coal tar is obtained by the distillation of bituminous coal (Ref. 5.3.). Coal tar pitch is composed almost entirely of polynuclear aromatic compounds and constitutes 48-65% of the usual grades of coal tar (Ref. 5.3.). The purpose of this work was to evaluate the sampling and
Depending on the requirements of materials, Berghof Fluoroplastics adds various additives to PTFE. The following additives are particularly suitable out of the many options: Glass (usually in the form of short fibres) Coal. Graphite. Metal powder (bronze, chrome nickel steel) Molybdenum disulphide. PEEK.

The solution was impregnated in porous PTFE membranes, and then evaluated for CO 2 permeation during sequential cycles. As can be seen from Fig. 8, the membrane did not lost performance for up to 15 cycles, having its permeation to CO 2 varied from 54 to 77 Barrer.
