摘要:
Herein disclosed is a method for hydrodesulfurization, hydrodenitrogenation, hydrofinishing, amine production or a combination thereof. The method comprises forming a dispersion comprising hydrogen-containing gas bubbles dispersed in a liquid feedstock, wherein the bubbles have a mean diameter of less than about 5 μm and wherein the feedstock comprises a mixture of petroleum-derived hydrocarbons and a naturally derived renewable oil. The feedstock comprises hydrocarbons selected from the group consisting of liquid natural gas, crude oil, crude oil fractions, gasoline, diesel, naphtha, kerosene, jet fuel, fuel oils, and combinations thereof. The method further comprises contacting the dispersion with a catalyst that is active for hydrodesulfurization, hydrodenitrogenation, hydrofinishing, amine production, or a combination thereof. The catalyst comprises homogeneous catalysts and heterogeneous catalysts. The catalyst may be utilized in fixed-bed or slurry applications.
摘要:
The present invention relates to a process for the selective conversion of hydrocarbon feed having a Conradson Carbon Residue content of 0 to 6 wt%, based on the hydrocarbon feed (8). The hydrocarbon feed (18) is treated in a two-step process. The first is thermal conversion (12) and the second is catalytic cracking (26) of the products of the thermal conversion (12). The present invention results in a process for increasing the distillate production (16) from a hydrocarbon feedstream for a fluid catalytic cracking unit. The resulting product slate from the present invention can be further varied by changing the conditions in the thermal (12) and catalytic cracking (26) steps as well as by changing the catalyst in the cracking step (26).
摘要:
A continuous liquid phase hydroprocessing process, apparatus and process control systems, where the need to circulate hydrogen gas through the catalyst is eliminated. By mixing and/or flashing the hydrogen and the oil to be treated in the presence of a solvent or diluent in which the hydrogen solubility is high relative to the oil feed, all of the hydrogen required in the hydroprocessing reactions may be available in solution. The oil/diluent/hydrogen solution can then be fed to a plug flow reactor packed with catalyst where the oil and hydrogen react. No additional hydrogen is required; therefore, the large trickle bed reactors can be replaced by much smaller tubular reactors. The amount of hydrogen added to the reactor can be used to control the liquid level in the reactor or the pressure in the reactor.

Disclosed is a method of manufacturing a diesel fuel base stock improved in low-temperature flowability, including: fractionating in a first fractionator a synthetic oil obtained by Fisher-Tropsch synthesis into at least two fractions of a first middle fraction containing a component having a boiling range corresponding to diesel fuel oil, and a wax fraction containing a wax component heavier than the first middle fraction; hydroisomerizing the first middle fraction by bringing the first middle fraction into contact with a hydroisomerizing catalyst to produce a hydroisomerized middle fraction; hydrocracking the wax fraction by bringing the wax fraction into contact with a hydrocracking catalyst to produce a wax-decomposition component; and fractionating in a second fractionator a mixture of the produced hydroisomerized middle fraction and the produced wax-decomposition component, wherein rectification conditions in the first fractionator and/or rectification conditions in the second fractionator are adjusted to selectively reduce an n-paraffin having 19 or more carbon atoms in a heavy component contained in the diesel fuel base stock. Furthermore, disclosed is a diesel fuel base stock obtained by the manufacturing method.
