Y-zeolite is one of the most popular catalyst used in petrochemical industry, which is also progressively degrading by coking. In this piece of work, the effects of volatilization/decomposition temperature and sample-to-catalyst ratio on the coke formed from heavy oil volatilization/decomposition in the presence of Y-zeolite catalyst have been investigated. Temperature plays a significant role in determining the nature of the carbon formed, with higher temperatures favouring a higher graphitic-to-amorphous carbon ratio. Higher sample-to-catalyst ratios lead to higher amounts of coke, but does not affect the graphitic-to-amorphous carbon ratio as the same volatilization/decomposition temperature. date: 2019-08 date_type: published publisher: Elsevier official_url: https://doi.org/10.1016/j.jaap.2019.104630 oa_status: green full_text_type: other language: eng primo: open primo_central: open_green verified: verified_manual elements_id: 1663483 doi: 10.1016/j.jaap.2019.104630 lyricists_name: Brett, Daniel lyricists_name: Manos, George lyricists_name: Owen, Rhodri lyricists_name: Shearing, Paul lyricists_name: Zhang, Yeshui lyricists_id: DBRET49 lyricists_id: GMANO86 lyricists_id: ROWEN61 lyricists_id: PSHEA33 lyricists_id: YZHAF94 actors_name: Stacey, Thomas actors_id: TSSTA20 actors_role: owner full_text_status: public publication: Journal of Analytical and Applied Pyrolysis volume: 141 article_number: 104630 issn: 0165-2370 citation: Zhang, Y; Owen, R; Shearing, P; Maskell, W; Brett, D; Manos, G; (2019) A study of coke formed by heavy oil volatilization/decomposition on Y-zeolite.
