A fluidized bed reactor that is operating in the bubbling regime has been developed for the conversion of bio-oils to syngas.The reactor consists of a 7.6 cm I.D. (or internal diameter) bed, with an expanded freeboard. The volume of the reactor can be adjusted to vary the gas residence time. This reactor has been used to carry out either thermal or catalytic cracking for reforming bio-oils.A ga...

The presence of polycyclic aromatic hydrocarbons (PAH) in the oil obtained at pyrolysis of Jordan oil shale in a fluidised-bed reactor in the atmosphere of nitrogen and nitrogen/steam has been investigated. The final pyrolysis temperature was 520 °C, at which the maximum oil yield was established. The derived oils were fractionated into chemical classes using mini-column liquid chromatography f...

Two-stage riser catalytic cracking of heavy oil for maximizing propylene yield (TMP) process proposed by State Key Laboratory of Heavy oil Processing, China University of Petroleum, can remarkably enhance the propylene yield and minimize the dry gas and coke yields, and obtain high-quality light oils (gasoline and diesel). It has been commercialized since 2006. Up to now, three TMP commercial u...

In this paper, fuzzy logic control of a fluid catalytic cracking unit (FCCU) is proposed. Fluid catalytic cracking (FCC) process is a unit that converts heavy distillates like gas oil or residues to gasoline and middle distillates using cracking catalyst. About 45% of worldwide gasoline production comes from FCC processes and its ancillary units. Since a typical FCC unit can process a large amo...

To address the issues of greenhouse gas emissions associated with fossil fuels, vegetable oilseeds, especially non-food oilseeds, are used as an alternative fuel resource. Vegetable oil derived from these oilseeds can be upgraded into hydrocarbon biofuel. Catalytic cracking and hydroprocessing are two of the most promising pathways for converting vegetable oil to hydrocarbon biofuel. Heterogene...

Gas-particle flows are involved in various industrial applications in the energy, oil and gas fields, like coal gasification, production of light hydrocarbons by fluid catalytic cracking, catalytic combustion and different treatments aiming to reduce or eliminate pollutants. In addition, gas-particle flows take part to interesting natural phenomena, like volcanic eruptions, and their understand...

Abstract Simulation of heavy oil thermal cracking process is very important but few researches have been published now. In this paper, a simulation framework based on the carbon number-based approach(CNCA) has been established. A systematic division rule is put forward for dividing cracked products into 59 carbon number components. Then the cracking reaction network has been structured and the ...

Tall oil fractions obtained from Norwegian spruce pulping were hydrodeoxygenated (HDO) at pilot scale using a commercial NiMo hydrotreating catalyst. Comprehensive two dimensional gas chromatography (GC×GC) showed that HDO of both tall oil fatty acids (TOFA) and distilled tall oil (DTO) produced highly paraffinic hydrocarbon liquids. The hydrotreated fractions also contained fatty acid methyl e...
