Here we report a Ni anode modified by BaZr0.9Yb0.1O3−δ particles that demonstrates stable performance in CH4 (without coking) and decreased sulfur poisoning.
The technology of desulfurization of coke during coking is conceptually designed, in which the coking oven gas (COG) is blown into the coking chamber of the coke oven during the coking stage.
Important open circuit potentials and power densities were reached by operating the fuel cells in the temperature range varying from 800 to 950 °C, without anode coking, carbon clogging and cracking phenomena.
DBD and catalyst hybrid reaction enabled higher CH4 and CO2 conversion without having serious coking problem.
The new anode material, described today in the journal Science, resists sulfur poisoning and carbon coking, even when running at low temperatures, and without compromising performance.
This work addresses the revamp study of the crude distillation unit (CDU) heat exchanger network (HEN) of a typical refinery with and without the consideration of the free hot streams available in the delayed coking unit (DCU).
Coke oven workers have a high probability of exposure to PAHs during the coking process.
Without the promoter Pt shows the same initial specific activity (TOF) on both supports, but deactivates rapidly due to coking.
(He later sold; Mrs. Coking did not).
With or without the presence of modifiers, the addition of H2S to the feed gives rise to a strong increment in the rate of catalyst coking.
