In the recent, literature study shows that different biomass
feedstock like oily seeds can be converted into various useful
products using pyrolysis for example hemp seed (liquid yield 40% at
350 C), safflower seed (liquid yield 44% at 500 C), castor
seed (liquid yield 64.4% at 550 C), tamarind seed(liquid yield
45% at 400 C), pistacia khinjuk seed (liquid yield 51% at
600 C) , Jatropha curcas L. (liquid yield 55% at 550 C) .
Above studies show that high liquid yield can be obtained at
temperature between 450 and 600 C and short vapor residence
time
