Please note: The word (petrol) is the British description of (gasoline). The biodiesel fuel is not intended to be blended with gasoline but it is usually blended with petroleum diesel (i.e. the fraction which is obtained by fractional distillation of crude oil in a refinery).

The combustion engine in a car (run on gasoline) differs from the engine in a car (run on diesel).

You seem a bit confused. Biodiesel is usually made my transesterification with methanol to make diesel. https://en.wikipedia.org/wiki/Biodiesel_production

Ethanol or higher alcohols can be produced from sugar or starches (like corn) and are commonly used as a gasoline (Petrol) additive. "Biodiesel" is not a good gasoline blend component -high Cetane # compounds (for diesel blending) almost always have low Octane numbers.

I observe you are a bit confused. Your questions are in two phases: (1) Production of biodiesel and (2) Blending.

Production of biodiesel can be employed using ethanol , methanol or other types of alcohol in the presence of catalyst.

As biodiesel is meant to be used in diesel engine/IC engines as Prof. Anastas Ivanov Ivanov rightly highlighted, you can blend with diesel/fossil diesel but not petrol. However, biodiesel can as well be blended with methanol, ethanol and nano particles based on the objectives of the researcher (e.g improve the cold flow properties such as pour and cloud points, and reduction of NOx). In developed countries, B20 is mostly used. Researcher have reported the effect of blending ratio of biodiesel with diesel on diesel engines.

Actually I am not confused I have produced biodiesel by transesterification with methanol, it able to dissolve with diesel but not dissolving with gasoline, by diluting with methanol it dissolves. Hence I have asked that question

I'm not sure what you mean by dissolve. I assume your biodiesel is liquid that mixes with conventional diesel. Are you trying to mix it wilth gasoline and having compatibility issues? Are you observing two liquid hydrocarbon phases? Why do you want to mix biodiesel with gasoline?

the methanol used to increase the octane number and ecological preservation but mix it with gasoline in different fraction and that is the compatible engine for these kinds of mixtures

Methanol is used as both a gasoline additive and a standalone motor fuel in China. In the US it is mostly sold as a petrochemical. There are some methanol vehicles - including some race cars but it is usually used to produce MTBE or DME if it is used in gasoline.

Bio Diesel can be blended with petroleum diesel in various amounts usually controlled on a volume or weight basis or a density gravity method. It should not contain free methanol or gasoline.

Thank you :)

It is a biodegradable and cleaner-burning alternative to petroleum diesel. Biodiesel can be blended and used in many different concentrations. They include B100 (pure biodiesel), B20 (20% biodiesel, 80% petroleum diesel), B5 (5% biodiesel, 95% petroleum diesel), and B2 (2% biodiesel, 98% petro- leum diesel

for the mixture bioethanol gasoline it is the mixture with better property is the E10 (10% bioethanol)

Simply can be blended with diesel fuel according to mass basis (by mass) or volume basis (by volume). Generally many papers in the open literature recommended 20% blended ratio as best blending ratio.
