Abstract: The factors responsible for the high chemical oxygen demand (COD) of biochemically treated coke-plant wastewater are identified. The factors responsible for overestimation of the COD in bichromate tests are also determined. Experiments show that the… read more here.

Abstract: Abstract—In the catalytic high-temperature hydrogenation (hydrodealkylation) of a mixture of raw coke-plant benzene and the 180–230°C naphthalene fraction of coal tar, water vapor (steam) acts in two ways: it blocks the smallest pores in the… read more here.
