[RAMUBAB]

HIII  FRIENDS..

please tell me any organic solvent or any suitable agent for reducing viscosity of palm sludge (which comes during processing of palm oil), we want to use palm sludge as a fuel for oil fired furnaces.

Hi Ramubab, you can write normally, I'm not deaf.

I doubt any agent used in tiny amounts can reduce viscosity radically.

Mixing with an other fuel of low viscosity works. Kerosene is well-known for that, and Diesel oil or very light heating oil would be candidates.

Heating the fuel works fine if you can. Both methods are used when burning rapeseed oil in Diesel car engines.

Transform the triglyceride in an ester is the standard method to get a fluid fuel (search for "di-ester") from a thick oil. Done industrially, easy enough for individuals to proceed at home, see the Web.

Though, I wonder (others here may know it better) if the carboxylic part can be removed from the fatty acid, since palmitic acid is saturated. This should mean:
React an acid to scoop the palmitic acid http://en.wikipedia.org/wiki/Palmitic_acid
Heat the palmitic acid to remove CO2
Get C15H32, resembling Diesel oil.
I presume it's less interesting than esterification.
