Catalytic cracking of vegetable oils and vacuum gas oil

Fuel, 2013
Abstract The effect of vegetable oil unsaturation on the distribution and composition of the products of oil conversion over an equilibrium cracking catalyst was studied. Co-conversion of vacuum gas oil and vegetable oils under catalytic cracking conditions make it possible to increase the yield of gasoline fraction by 10 wt.%.

Hydrocracking of vacuum gas oil-vegetable oil mixtures for biofuels production

Bioresource Technology, 2009
Hydrocracking of vacuum gas oil (VGO)--vegetable oil mixtures is a prominent process for the production of biofuels. In this work both pre-hydrotreated and non-hydrotreated VGO are assessed whether they are suitable fossil components in a VGO-vegetable oil mixture as feed-stocks to a hydrocracking process.

Co-processing of Hydrothermal Liquefaction Biocrude with Vacuum Gas Oil through Hydrotreating and Hydrocracking to Produce Low-Carbon Fuels

Energy & Fuels, 2020
In this study, we investigate the potential of co-processing hydrothermal liquefaction (HTL) biocrude with vacuum gas oil (VGO) in a hydrocracking process with hydrotreating as the first step.

Catalytic cracking of heavy vacuum gas oil

Applied Catalysis, 1986
Abstract Four fractions of Wilmington crude oil in the boiling point range 375 – 630°C were analyzed for their chemical and physical properties and used as feeds in catalytic cracking testsat 560°C. The contributions to the activity of the catalyst from the matrix and from thermal reactions were separated from that of the zeolite. The activity of the

Extraction Refining of Heavy Vacuum Gas Oil

Russian Journal of Applied Chemistry, 2001
Selective refining of heavy vacuum gas oil and a combined fraction of light and heavy vacuum gas oils to remove aromatic and organoelement compounds and heavy metals by five-step countercurrent extraction with N-methylpyrrolidone or dimethylacetamide in the presence of heptane containing 1 wt % toluene was studied.

Tuning the morphology and textural properties of ZSM-5 additive for co-cracking of waste plastics with vacuum gas oil to light olefins.

Waste Management
Typical cracking catalysts, called equilibrium catalyst (E-Cat) are ultra-stable Y (USY) zeolite often used with 15% commercial ZSM-5 zeolite additive (ZSM-5(COM)) to boost olefin yield.

Extraction Refining of Light Vacuum Gas Oil

Russian Journal of Applied Chemistry, 2001
Highly selective refining of light vacuum gas oil by five-step countercurrent extraction of aromatic and heteroatomic compounds with N-methylpyrrolidone or dimethylacetamide in the presence of low-boiling nonpolar solvents was studied. The resulting refined oil can be used as high-quality raw material in hydrocracking and catalytic cracking.

Sustainable design and optimization of co-processing of bio-oil and vacuum gas oil in an existing refinery

, 2020
In order to lower the production cost of bio-fuels and add renewable carbon into the fossil fuels, the co-cracking of bio-oil and vacuum gas oil (VGO) has been proposed by utilizing the existing infrastructures in a refinery.
