What catalyst is used for biodiesel production?
Strong alkali catalysts such as NaOH, KOH, CH3ONa and CH3OK (potassium methoxide) are used for biodiesel production. However, alkali metal alkoxides are found to be more active than hydroxides .
What technology is used to produce the biodiesel?
Transesterification of oils. The most common technology of biodiesel production is transesterification of oils (triglycerides) with alcohol which gives biodiesel (fatty acid alkyl esters, FAAE) as main product and glycerin as by product.
What equipment do you need to make biodiesel?
At minimum, the equipment you’ll need for home biodiesel production is a stainless steel reactor tank, a wash station to remove the coproducts, and containers for storing the resulting fuel. You can rig up an electric water heater as a biodiesel reactor for less than $1,000, or spend about the same amount on a kit.
What are the 5 sources of feedstock for biodiesel?
- Article 2 Feedstock : Borage Oil & Camelina Oil.
- Article 3 Feedstock : Algae Oil & Canola Oil.
- Article 4 Feedstock : Castor Oil and Choice White Grease.
- Article 5 Feedstock : Coconut Oil and Coffee Oil.
- Article 6 Feedstock : Evening Primrose Oil and Fish Oil.
What affects biodiesel production?
Biodiesel can be produced from plant and animal fats through transesterification reaction. The transesterification reaction is affected by molar ratio of alcohol, presence of water and Free Fatty Acid content, reaction temperature, catalyst concentration and agitation speed.
How can biodiesel production be improved?
In biodiesel production, increasing temperature will increase how quickly biodiesel is produced. A study by Freedman et al. (1984) with soybean oil found that a temperature of 140°F could produce 94% of the total biodiesel yield in about 6 minutes versus a yield of 64% at 90°F (Fig. 4).
What is the best crop for biodiesel?
In the United States, soybeans are the dominant biodiesel feedstock.
- Soybeans. Soybeans produce approximately 1.5 gallons of oil per bushel.
- Rapeseed and Canola.
- Safflower and Sunflower.
- Potential Oilseed Crops.
- Used and waste oil.
- Animal Fats.
Which of the following factors affect the transesterification process?
The transesterification reaction isaffected by molar ratio of alcohol, presence of water and Free Fatty Acid content, reactiontemperature, catalyst concentration and agitation speed.
How are microreactors used for biodiesel synthesis?
Regarding biodiesel synthesis in microreactors through the use of modeling and simulation, literature is even scarcer. Thus, this work aims to discuss the different microdevice designs for biodiesel synthesis and to present how modeling and simulation can be a new approach in the development of microsystems for biodiesel synthesis in microscale.
How many channels does a micro reactor have?
Micro-reactor scaling-up. The aim of this work is to increase the micro-reactor productivity; therefore, single, ten and twenty channels micro-reactors are developed and implemented, in addition, scaling-up using three micro-reactors of multi-channels (20 channels), which is elaborated to achieve high production capacities.
Is the micro-reactor technology a promising tool?
The state-of-the-art of micro-reactor technology has an excessive potential as a promising tool for reactor development and reactor scaling-down, it is one of the auspicious progressive know-how in a chemical engineering field, particularly in the production of a fine chemical.
How are microreactors used in conventional industrial processes?
In the conventional scale processes, researchers and industry professionals apply modeling and simulation techniques in an usual way to develop and optimize equipment and industrial processes. As reported by Hessel et al. , microreactors’ modeling and simulation are still new when compared to conventional scale.
