Hydrocracking of Maya crude oil in a slurry-phase reactor. I. Effect of reaction temperature

Effect of Temperature on Gas and Liquid Products Distribution in Thermal Cracking of Nigerian Bitumen

“…This phenomenon could be associated with the breaking down of the paraffinic chains present in asphaltenes and other large molecules present in the bitumen in the early stage of the reaction, and with the cracking of smaller ones in the latter stages of the reaction. The obtained result was similar to the one reported by Martinz-Grimaldo and co-workers [28].…”

Promotion effects with dispersed catalysts for residue slurry hydroconversion

“…At 450°C, when reaction time was varied (t 0 , 30 min, 45 min and 60 min), we observed that gas production increased linearly with the reaction time as illustrated by Fig. 1 and similarly to Martinez-Grimaldo et al [18] at 410°C. Fig.…”

Formation of hydrocarbon compounds during the hydrocracking of non-edible vegetable oils with cobalt-nickel supported on hierarchical HZSM-5 catalyst

“…The non-edible vegetable oil of 200 ml was placed into the reactor, which was containing the catalysts of 1 g. Then, a reactor was purged with nitrogen to remove air dissolved in oil for 30 min, as reported in previous study [13]. The catalyst was activated under flowing H 2 for 1 h. In previous study, Martinez-Grimaldo et al [14] activated hydrocracking catalyst at 350 o C for 1 h. The reaction temperature was carried out at a temperature of 400 o C for 2 h. In practically, the reaction pressure changed between 10 bar and 15 bar. Liquid products were analyzed by gas cromatography-mass spectrometry with standard GC : Agilent HP 6890 models 19091S-433, HP-5MS capillary column 30 m x 250 µm x 0.25 µm.…”
