P 22077 The coke yield over the nanoparticles

In addition, for TiNi2 and AlNi2 nanoparticles, it was found that coke yields were approximately 0.17 and 0.13 ± 0.02 wt%, indicating that functionalizing the supports with NiO inhibited coke formation more effectively. However, the highest enhancement in coke inhibition was obtained with the PdO-functionalized nanoparticles, with which no significant residue could be observed after gasification; secondary xylem could be related to the inhibition of asphaltene self-association on the nanoparticles surface. Results indicate that functionalized nanoparticles were able to inhibit coke formation to different extents and hence prevent catalyst poisoning.
