Two alkyl-bridged aromatic compounds, with molecular weights of 899.70 g/mol and 1127.99 g/mol, were thermally cracked with 1-hexadecene, 1- octadecene, or trans-stilbene, in a batch microreactor at 375–430 °C for 15 to 45 min. The objective of the study was to investigate the kinetics of the...
Agglomerate formation is a common phenomenon that can cause operating problems in the fluid coking reactor. When agglomerates form they provide longer diffusion paths of the reaction products through the liquid layers and liquid bridges within the agglomerate, which leads to higher mass transfer...
Thermal cracking of the vacuum residue fraction of bitumen and petroleum is an important feature of several refinery processes. At normal process temperatures, this fraction remains liquid, which favors coke formation. In order to understand the reaction yields and intrinsic reaction kinetics of...
Resolution of reaction pathways to coke formation during the upgrading of heavy resources, such as the vacuum residue fraction of bitumen, is hampered by the extreme complexity of these materials. Alternatively, probing the molecular–level reactions and cracking kinetics of model compounds that...
There are increasing social and economic pressures to develop renewable alternatives to fossil derived fuels and chemicals as well as renewable and biodegradable industrial and consumer products and materials. This has led to renewed focus on converting agricultural and forestry feedstocks...
Better definition of asphaltene structure is needed to develop new technology for upgrading, and to understand various bitumen properties. Analysis of asphaltene structure is hampered by aggregation of molecules at a length scale of 5 to 10 nm. At 300°C, the addition of aromatic solvents can...
