Process simulation and evaluation of alternative solvents for jatropha curcas l seed oil extraction in biodiesel production (august 2011) ming-hao chiou, bs, national chung hsing university. The amount of raw oil content in the seed again depends on the quality of the seed the output of the raw oil from the extraction unit is a key determining factor for deciding the capacity of the transesterification unit the cost of the extraction stage is based on the capacity of the extraction plant, which, in turn, is based on the seed yield. Jatropha curcas l seeds were obtained during the month of november, 2014 from the locality of sta maria, bulacan, philippines the plant material was taxonomically identified research article abstract seeds of jatropha curcas l collected from the locality of sta maria, bulacan, philippines were utilized in the study. (piecing together the puzzle for jatropha curcas being a source for biodiesel) i just received an interesting report about using jatropha bushes for biodiesel production titled: “best practices for long-term jatropha development, a position paper by knowgenix jatropha curcas is being heavily planted for harvesting of it nuts to produce biodiesel.
Jatropha oil is extracted from jatropha seeds using a jatropha oil extraction machine the yield of these seeds determines the volume of the oil to be extracted. Domestication and breeding of jatropha curcas l recent ﬁndings indicate that the seed yield of jatropha at maturity nutrient extraction from the soil . Jatropha can be a competitive feedstock when compared to soybeans and rape seed, which produce lower oil yields than jatropha (us doe 2010 figure 5) the seed kernel contains predominantly crude fat (oil) and protein, while the seed coat contains mainly fiber (brittaine and lutaladio 2010).
Kiwi seed oil has a nutritionally interesting fatty acid profile, but a rather low oxidative stability, which requires careful extraction procedures and adequate packaging and storage for these reasons and with the aim to achieve process intensification with shorter extraction time, lower energy consumption and higher yields, four different non-conventional techniques were experimented.
