Top 10 Questions for Biodiesel Technology Development Manager Interview

1. Can you explain the process of biodiesel production and highlight the key factors that affect the efficiency of the process?

The process of biodiesel production involves converting vegetable oils or animal fats into a renewable and non-toxic fuel. The key steps are:

• Feedstock selection: Choosing the right feedstock (e.g., soybean oil, palm oil, waste cooking oil) is crucial as it influences yield and quality.
• Pretreatment: Removing impurities and contaminants to improve conversion efficiency.
• Transesterification: Reacting the feedstock with an alcohol (e.g., methanol, ethanol) to form biodiesel and glycerol as a byproduct.
• Purification: Washing and drying the biodiesel to remove impurities and meet quality standards.

Efficiency is influenced by factors such as:

• Feedstock quality
• Reaction temperature and time
• Catalyst type and concentration
• Alcohol-to-oil ratio

2. Describe the different technologies used for biodiesel production and discuss their advantages and limitations.

Biodiesel can be produced using various technologies:

• Base-catalyzed transesterification: Utilizes a strong base (e.g., sodium hydroxide) and offers high conversion rates. However, it produces significant wastewater.
• Acid-catalyzed transesterification: Employs an acid (e.g., sulfuric acid) catalyst and generally results in lower conversion rates but reduced wastewater production.
• Enzymatic transesterification: Uses immobilized enzymes as catalysts, leading to high product purity but slower reaction rates and higher costs.
