The slurry phase hydrocracking of vacuum residue was investigated by Kim et al9.

The experimental conditions varied in a wide range of temperature, pressure, andFile Size: 1MB. Abstract. Residue hydrocracking has been attracting more and more attention to the refining industry in recent years, and one of the best approaches is ebullated bed residue hydrocracking (EBRH).

STRONG ebullated bed residue hydrocracking uses a new type of reactor, and a 50 KTA demonstration unit has been put into operation by: 1. Comparing the type distribution in each product, it is suggested that, with the use of Al 2 O 3-B 2 O 3 catalyst, main reaction of TK-AR hydrocracking was the hydroconversion of aromatics in feedstock to saturates and naphthenic compounds in gas oil, while USY catalyst converted all types in residual oil to naphtha, kerosene and gas oil Cited by: 6.

Residual oil fairways. Similar residual oil targets also occur in many hydrocarbon basins in so-called residual oil zone fairways, which have recently been investigated as a potential new type of geological storage target.

Residual oil fairways occur within saline aquifers on the paths along which oil migrated over geological time before reaching current oil reservoirs.

In this article, we will focus on cocurrent downflow, which, because of its relatively lower pressure drop and the absence of flooding, is by far the most common mode of operation in industrial practice. Trickle-bed reactors are used primarily in the petroleum industry for hydrocracking, hydrodesulfurization.

hydrocracking, hydrovisbreaking, donor-solvent processes. Carbon rejection processes: coking, visbreaking, and other processes such as solvent deasphalting. Both hydrogen addition and carbon rejection processes have disadvantages when applied to upgrade heavy oils or residua.

For instance, removal of nitrogen, sulfur andFile Size: KB. hydrocracking Hydrocracking Severe form of hydroprocessing •Break carbon‐carbon bonds •Drastic reduction of molecular weight Reduce average molecular weight & produce higher yields of fuel products 50%+ conversion Products more appropriate for diesel than gasoline 5File Size: 2MB.

Many oil refineries employ hydroprocessing for removing sulfur and other impurities from petroleum feedstocks. Capable of handling heavier feedstocks than other refining techniques, hydroprocessing enables refineries to produce higher quality products from unconventional- and formerly wasted- by:   Purchase Hydrotreatment and Hydrocracking of Oil Fractions, Volume - 1st Edition.

Print Book & E-Book. ISBNBook Edition: 1. Distillate hydrocracking is a refining process for conversion of heavy gas oils and heavy diesels or similar boiling-range heavy distillates into light distillates (naphtha, kerosene, diesel, etc.) or base stocks for lubri- cating oil Size: 1MB.

Figure 1. Catalytic hydroprocessing units within a refinery, including distillate hydrotreating and hydrocracking. Catalytic hydroprocessing of liquid biomass is a technology that offers great flexibility to the continuously increasing demands of the biofuels market, as it can convert a wide variety of liquid biomass including raw vegetable oils, waste cooking oils, animal fats as well as Cited by: Hydrocracking of heavy oils with metal dispersed catalysts is the most suitable to obtained low boiling point or middle distillate with high value products.

In order to understand the catalytic behavior in slurry-phase reactor, several model substrates are utilized and Cited by: It is pointed out in the conclusion that from heavy, high-resin crude oils and tars, containing up to 70% residue above degree C, approximately 61% by weight of motor fuels can be obtained.

UOP has long experience in designing “black oil” units as UOP was the first licensor to commercialize residue hydrotreating. The RCD Unionfining process is a fixed-bed catalytic hydrotreating process, combining unique process design parameters with state-of-the-art residue hydrotreating catalysts.

We provide solutions for the integration of. In principle there are two solutions for upgrading residual oils and for obtaining a better product distribution. These are carbon out and hydrogen in processes.

Examples of carbon rejection processes are the Flexicoking process (Exxon) and the FCC process discussed earlier.5/5(1).

Theme description In the refinery sector, both the fuel and the feedstock market as well as the more stringent environmental regulations are exacerbating the need of maximizing the residue conversion .Residue upgrading helps refiners get more from a barrel of oil and adds more to your bottom line.

UOP offers various solutions for upgrading both atmospheric and vacuum residue streams. The choice of technologies depends upon both the quality of the resid stream and the quality of .Residual oil is oil found in low concentrations naturally or in exhausted oil fields.

Often mixed with water, it cannot be recovered by conventional techniques. However, part of it can be recovered using carbon dioxide-enhanced oil recovery (CO2 EOR) which involves injecting carbon dioxide into the well reducing viscosity and enhancing flow of the oil.

The technique is not new but has not.
