Furnace carbon blacks

Typical applications in the chemical field (Beaver, op. cit.) include detarring of manufactured gas, removal of acid mist and impurities in contact sulfuric acid plants, recovery of phosphoric acid mists, removal of dusts in gases from roasters, sintering machines, calciners, cement and lime Idlns, blast furnaces, carbon-black furnaces, regenerators on fluid-catalyst units, chemical-recoveiy furnaces in soda and sulfate pulp mills, and gypsum kettles. Figure 17-74 shows a vertical-flow steel-plate-type precipitator similar to a type used for catalyst-dust collection in certain fluid-catalyst plants.

Carbon black, which was produced by the smoke-impingement process by the Chinese over 1000 years ago, is now the most widely used filler for polymers. Much of the 1.5 million tons produced annually is used for the reinforcement of elastomers. Furnace carbon black is the most widely used carbon black.

We have chosen to present below the results obtained on furnace carbon black N115, because of its intermediate surface area of 145 m2 g-1. The fitted high resolution XPS spectra of Cls and FIs components are given in Fig. 23. Due to the complexity of the morphology of carbon blacks, ten components were required, in order to take into account the envelope of the Cls spectra. Details of the fitting procedure can be found in [101], The different assignments for C and F atoms involved in each component are shown in Table 7. For Cls envelope, there are two major peaks. The peak at lower BE, located at 284.3eV, can be assigned to the component Cls (1) which corresponds to non-functionalised sp2 and sp3 C atoms that are not affected by fluorination. The area of component (1), which is noted...

The low-pressure adsorption isotherms of microporous carbons differ considerably from the previous examples. In micropores, assumed to be slit-like in carbons, adsorbed molecules interact with two surfaces, as opposed to just one on an open surface. Thus, on microporous carbons significant adsorption already occurs at low pressures and is much larger as compared to an open surface. This is also the case in comparison to an open surface that contains defects. For example, at a P/Pq of 10 on the microporous CB, approximately 10% of the monolayer is already formed (Fig. 18.4), whereas on the nonmicroporous thermal and furnace carbon black, less than 2% are formed (All data are presented in Fig. 18.3).
