“…It is reported by Baker and Harris (1976) that continuous addition of sulfur compounds to the gas phase inhibits carbon deposition onto Fe304, Cr203, and stainless steel. The same is reported by Durbin and Castle (1976) and Kishi and Roberts (1975). H2S has been found to reduce the amount of carbon deposited on iron and nickel surfaces.…”

“…In a previous study in our laboratory, polishing 304 stainless steel and Incoloy coupons demonstrated significant carbon reduction (by 80% or more) during pyrolysis of both isobutane and n-butane (Chen, 1987). Durbin and Castle (1976) polished various metal samples to study carbon deposition from pyrolysis of acetone. They reported no effect from this polishing, presumably because of surface annealing as the temperature of the samples was raised.…”

The objective of this study was to determine if polishing Incoloy 800 metal coupons significantly reduced coke formation during pyrolysis of light hydrocarbon feedstocks. All experiments were conducted at 700 °C, 1 atm, and 1-h contact and using methane, ethane, ethene, propane, propene, and isobutane. The ratio of carbon formed from the unpolished coupons to that from polished varied from a low of 5.6 for isobutane up to 28.1 for ethene; most were between 5.6 and 7.9. The polishing

“…Similarly, Marek and Albright [22,23] and Gregg and Leach [24] also found reduced coke formation on the metal surface after polishing. However, Durbin and Castle [25] found that the amount of coke on a polished specimen did not drop compared with the unpolished specimen during acetone pyrolysis. They explained that this might be because of the increasing temperature on the metal surface during the process of heat treatment.…”

Comparison of Growth Characteristics and Properties of CVD TiN and TiO2 Anti-Coking Coatings

Coating metals with anti-coking materials inhibit their catalytic coking and are especially beneficial in the pyrolysis of hydrocarbon fuels. It is believed that growth characteristics and properties may play a pivotal role in the anti-coking performance of chemical vapor deposition (CVD) coatings. In this study, TiN and TiO 2 coatings were obtained by CVD using TiCl 4 -N 2 -H 2 and TiCl 4 -H 2 -CO 2 systems, respectively. The effects of deposition time, residence time, and partial pressure were examined, and the coating microstructure was characterized by scanning electron microscopy (SEM). The results reveal that the effect of deposition parameters on the growth characteristics of TiN and TiO 2 coatings is very different. The growth of the TiN coating shows characteristics of the island growth model, while the TiO 2 coating follows the layer model. In general, the growth rate of the star-shaped TiN crystals is higher than that of crystals of other shapes. For the TiO 2 coating, the layer mode growth characteristics indicate that the morphology of the TiO 2 coating does not change significantly with the experimental conditions. Coking tests showed that the morphology of non-catalytic cokes is not only affected by the temperature, pressure, and coking precursor, but is also closely related to the surface state of the coatings. Both TiN and TiO 2 coatings can effectively prevent catalytic coking and eliminate filamentous cokes. In some cases, however, the N or O atoms in the TiN and TiO 2 coatings may affect common carbon deposits formed by non-catalytic coking, such as formation of needle-like and flaky carbon deposits.
