Abstract: | The combined catalytic reactions using different types of petroleum residuum and coal were performed at 425°C and 60 minutes
in the presence of hydrogen to upgrade both materials to high quality synthetic fuels. In order to improve this coprocessing
technology, the effect of the chemical and physical properties of both materials on the coprocessing product yields was investigated
through a parametric study. In all reaction combinations, substantial increase in maltene production and high coal conversions
of over 84% were observed regardless of petroleum residuum type and coal rank. The petroleum residuum properties of specific
gravity and conradson carbon residue had effects on asphaltene production and coal conversion. The results of quantitative
analysis for the amount of coal upgraded during coprocessing lead to conclude thata large amount of coal converted to maltene fraction due to high catalytic activity and reactive hydrogen donor richness of
coprocessing system. However, most of the heavier fractions were formed primarily from coal regardless of the type of residuum
used. |
