WebJun 21, 2024 · The catalytic evaluation for dodecane cracking at 550 °C shows the gas yield as the main product with naphtha as a side product. The gas yield consisted of 50% light olefins from ethylene to butene. However, the process yielded 9% of coke that led to faster catalyst deactivation because of nanozeolite-Y evolution and product transformation. WebThe catalytic cracking of n-dodecane over HZSM-5 zeolite catalyst was investigated at 400-450 °C under supercrit. and subcrit. pressures (0.1-4.0 MPa). The results show that both the activity of the catalyst and its stabilization towards deactivation decrease with … pubs.acs.org We would like to show you a description here but the site won’t allow us.
