Furnace Black

The Furnace Black process is the most common production method of

Carbon Black. It uses liquid hydrocarbons as feedstock and natural gas

as heat source.

The Furnace Black method offers a great flexibility in producing

a multitude of Carbon Blacks without the need to change

equipment or feedstock.

In addition, the Furnace Black process offers the best environmental

and work safety benefits as it is fully enclosed, reducing the

emission of process gases

Gas Black Process

The Gas Black process was developed in the mid-1930s by DEGUSSA A. G.. It is a continuous process using vaporized

oils as feedstock. In contrast to the Furnace Black process,

the range of particles is quite small and consistent. This consistency is one big advantage of the Gas Black Process

as it facilitates the predictability of the product characteristics

and avoids complex readjustments of the production equipment. Another unique advantage of the Gas Black Process is the constant supply of oxygen during the production cycle, which imparts very special acidic characteristics, not provided by other Carbon Black processes. The final product is almost exclusively used in coating and printing industries, as the fine particles are of a special interest in these segments.
