Conversion of flaxseed oil into biodiesel using KOH catalyst: Optimization and characterization dataset

Area of Science:

• Chemical Engineering
• Renewable Energy Sources
• Biomass Conversion

Background:

• Biodiesel production from vegetable oils is a key area in renewable energy research.
• Flaxseed oil is a viable feedstock for biodiesel due to its fatty acid profile.
• Optimization of transesterification process parameters is crucial for maximizing biodiesel yield.

Purpose of the Study:

• To optimize the process variables for biodiesel production from flaxseed oil.
• To determine the optimal conditions for transesterification using KOH catalyst.
• To achieve a high biodiesel yield from flaxseed oil.

Main Methods:

• Utilized response surface methodology (RSM) with a face-centered central composite design (FCCD).
• Investigated independent variables: methanol oil ratio, KOH catalyst weight, temperature, and reaction time.
• Analyzed biodiesel yield as the response variable.

Main Results:

• The maximum biodiesel yield achieved was 98.6%.
• Optimal conditions were identified as a methanol oil ratio of 5.9:1, 0.51% KOH catalyst, 59.2°C, and 33 minutes reaction time.
• Analysis of Variance (ANOVA) confirmed the statistical significance of the optimized parameters.

Conclusions:

• Response surface methodology effectively optimized the transesterification process for flaxseed oil biodiesel.
• The study demonstrated a highly efficient method for producing biodiesel from flaxseed.
• The optimized process offers a sustainable route for biodiesel generation with high yield.
