“…The pyrolysis of methyl ricinoleate is the preferred method since castor oil has a higher viscosity, thus resulting in tarry materials and poisonous gases during its direct pyrolysis [7,61,77]. Many studies have been performed considering different pyrolysis temperatures [7,61,77,[87][88][89]. For instance, Vernon and Ross have shown that the glycerol portion of the castor oil molecule is degraded at around 425 7C, giving acrolein [87].…”

“…On the other hand, Lima et al [93] emphasize that the pyrolysis of castor oil can be performed between 350-400 7C. Recently, Figueiredo et al [89] reported a more feasible and low-energy cost process, the low-temperature pyrolysis process at 380 7C of castor seeds yielding 50 wt-% of pyrolysis oil. Today, at the industrial level, castor oil is still reacted with superheated steam at high pressure, even if this operation is very energy intensive and often produces colored materials that contain polymerized byproducts (polyricinoleic acids) [87].…”

“…some 50 wt.%, but also by some compounds resulting from a partial degradation of the lignin matrix of the seed. In a parallel study, Figueiredo et al 26 focused their work on a fine analysis of the products obtained from castor seed pyrolysis and compared the pyrolysis yields in liquid products with three other raw feeds: soybean seeds, soybean tort and Jatropha curcas tort. Fractions of the obtained biooils were also submitted to a number of characterizations in an attempt to understand their potential as an additive to mineral diesel.…”

“…Figueiredo et al [14] founded that the fatty acids such as 9-octadecenoic acid (9Z, 12Z)-octadecadienoic acid and (8Z, 11Z)-octadecadienoic acid could be produced by pyrolysis of castor seeds. But in this work, the fatty acid and fatty acid methyl esters were produced by pyrolysis of oleaginous fermented mass.…”
