How is titration used in biodiesel?

How is titration used in biodiesel?

Acid/Base Titration The process of titration works to neutralize free fatty acids present in both regular and wast vegetable oils. Being on the opposite end of the pH scale, a base will balance out an acid.

Why is heated waste vegetable oil titrated?

When vegetable oil is heated extensively during the cooking process it causes the formation of free fatty acids (FFA’s). These FFA’s when combined with a base catalyst such as Potassium Hydroxide (KOH) or Sodium Hydroxide (NaOH) will form soaps.

Is biodiesel an acid?

Biodiesel, which refers to fatty acid alkyl esters, has attracted considerable attention as an environmentally friendly alternative fuel for diesel engines, and biodiesel has several advantages as a renewable, biodegradable, and nontoxic fuel.

How do you make biodiesel from waste cooking oil?

Transesterification is the chemical process that transforms waste oil into diesel fuel. It’s a long name for a relatively simple concept. During this process, we combine an ester with an alcohol. In the case of biodiesel, the “ester” is used cooking oil, which is combined with methyl alcohol, or methanol.

What is the chemical formula for biodiesel?

It is a straight-chain hydrocarbon with a molecular formula C2H5OH, and is sometimes written EtOH. Figure 2 Molecular structure and 3-D model of ethanol.

How do you calculate biodiesel yield?

Popular Answers (1)

  1. Yield of biodiesel(%) =mass of biodiesel obtained / mass of oil used. Normally we get an yield of 95-100%.
  2. Ester Content (%)= cumulative mass of methyl esters/ mass of biodiesel.
  3. Conversion Efficiency(%).

Why biodiesel is an attractive fuel?

Biodiesel is a domestically produced, clean-burning, renewable substitute for petroleum diesel. Using biodiesel as a vehicle fuel increases energy security, improves air quality and the environment, and provides safety benefits.

Can I put biodiesel in my diesel car?

Biodiesel and conventional diesel vehicles are one and the same. Although light-, medium-, and heavy-duty diesel vehicles are not technically alternative fuel vehicles, almost all are capable of running on biodiesel blends. B20 and lower-level blends can be used in many diesel vehicles without any engine modification.
