Alternative Processing Technology for Converting Vegetable
Jun 1, 2008So vegetable oils (palm oil and soybean oil) and animal fats (chicken fat) were used as FCCfeed solely or blending VGO in the laboratory-scale TSRFCC unit. For palm oil cracking
In the presence of the catalyst (3%), the maximum conversion was 99.7% at the ethanol-to-oil molar ratio of 10:1 and 100 °C in 180 min whereas in the absence of the catalyst,

2012 Biodiesel Diesel Fuel. mass transfer rate between oil and alcohol phase.75鈭?7 found that with the use of biodiesel as a cosolvent, a high Introducing a cosolvent into the
Green Diesel Production by Catalytic Hydrodeoxygenation
A valuable alternative to biodiesel is green diesel, which is obtained by the catalytic deoxygenation (DO) of vegetable oils. DO is a thermal process, typically conducted in a hydrogen atmosphere
The maximum biodiesel yield of 97% was attained at 75 °C with 1 wt% catalyst concentration and oil-methanol molar ratio of 1:06 at 350 rpm and 90 min. Also, these process
State of the art of vegetable oil transformation into biofuels
Vegetable oils do not dissolve in water, which make the separation easier, due to the polarity difference between water and vegetable oil molecules. The viscosity of plant oils is
The process involves transesterifying vegetable oil with methanol in two fixed-bed reactors with glycerol separation, enhancing triglyceride conversion. Ban et al. [ 132 ] reported a simulation of
Simulation of the soybean oil hydrotreating process for green
Mederos-Nieto et al. (2018) simulated the hydrotreatment of vegetable oil in Aspen Plus® v10 with two different raw materials from the same plant: crude castor oil (RCO) and castor
were a 9:1 ratio of methanol/oil, 6% by weight of catalyst load (g), reaction of 130 min at 65 C, and allowed the conversion of 96% of ester [ 59 ]. 2.2.3.
Passion Fruit Seed Oil as Alternative Feedstock for Biodiesel
Edible and non-edible seed oil crops have proven to be recognized sources of vegetable oils for biodiesel production, although the production process has been developed for edible seed oil,
Jun 25, 2005Freedman compared both crude and refined vegetable oils as feedstocks and found that the yield of methyl esters was reduced from 93% to 98% for the refined oil to 67% to 86% for

In the presence of the catalyst (3%), the maximum conversion was 99.7% at the ethanol-to-oil molar ratio of 10:1 and 100 °C in 180 min whereas in the absence of the catalyst,
Effect of free fatty acids contents on biodiesel quality. Pilot plant
Biodiesel was produced from 100 L of used frying oil in the pilot plant using the optimum conditions. A simplified process flow schematic for biodiesel production is shown in Fig.
Review of the hydrotreating process for conversion of vegetable oil into renewable diesel fuel. Plant-derived fuels can be a substitute for fossil fuels. However, the raw oil (straight
- Can vegetable oil blends be processed in a FCC small scale pilot plant?
- Blends of VGO (visbreaker gas oil) and vegetable oils as well as pure vegetable oils could be processed successfully in a fully continuous FCC small scale pilot plant. No fundamental modifications were necessary during the test runs. The system did not encounter any difficulties.
- Is co-processing of vegetable oils with conventional feedstocks a good idea?
- Co-processing of vegetable oils with conventional feedstocks in existing FCC plants is a promising option*. The advantages include small required investments and the use of large-scale facilities with high conversion efficiencies [17], [18], [11].
- What is the optimum methanol-to-oil ratio for biodiesel conversion?
- The highest biodiesel conversion was achieved by the combination of 20/28 kHz. Under the optimum conditions (methanol-to-oil molar ratio 8:1, catalyst content 1.8%, the water content less than 0.4%, the acid value less than 2 mg KOH/g), the biodiesel conversion was 96.3%.
- How to convert acid oil to biodiesel?
- The process produced biodiesel of high quality, but the product yield was only 60% of the theoretical yield. A two-step enzymatic process for conversion of acid oil to biodiesel consisting of hydrolysis of AGs by lipase followed by esterification of FFAs with methanol by another lipase has been used [41, 42].
- What happens to the conversion of vegetable oil to hydrocarbons?
- During the catalytic conversion of vegetable oils, the process decreases at higher blends of vegetable oil. It is important to note that vegetable oils contain around 11 wt.% oxygen, which cannot be converted to hydrocarbons.
- Is microwave assisted in continuous biodiesel production from waste frying palm oil?
