Dear all,
I am currently doing a research for my FYP project which is on a production of biodiesel. Have read through a lot of journal and research papers, however there was no any producing results according the usual papers when we were doing it in lab. We are trying to produce a biodiesel through enzymatic catalyst which is mainly the lipases enzyme from the waste cooking oil. So far we had followed using a 50g of WCO, Methanol : oil ratio = 6:1 , 6% of enzyme loading and the reaction time would be from 6 to 8 hours. Any suggestions on how we could improve it ?
Thank you
According to Digambar Singh and Vegneshwaran V. Ramakrishnan and several other experts, the optimum parameters for biodiesel production can vary depending on the feedstock and the specific process. Here are some key factors to consider:
- Different feedstocks (such as palm, soybean, or salmon oil) have varying properties and optimal conditions.
- For palm oil-based biodiesel, the transesterification method is commonly used.
- For salmon oil, a 10% enzyme concentration, a temperature of 45°C, a reaction time of 16 hours, and a 1:4 oil/alcohol molar ratio led to an 87.23% biodiesel yield.
- Molar ratio between alcohol and triglycerides: Excess alcohol ensures complete conversion of fats or oils to esters.
- Reaction time: Longer reaction times may improve yield but should be balanced with efficiency.
- Catalyst: Sodium hydroxide or potassium hydroxide is commonly used.
- Reaction temperature: Typically, around 60-70°C.
It is important to stress that these parameters can vary based on the specific feedstock and process. Optimizing them for each case is essential to achieving the best biodiesel yield and quality.
