Production of biofuel and biochar by thermal pyrolysis of linseed seed

The pyrolysis oil produced from nonfood related biomass can be used both as an energy source and a feedstock for chemical production. In the present work, linseed seeds (Linum usitatissimum L.) were pyrolyzed in a semibatch rector at a temperature range of 350-575 degrees C and at a heating rate of 20 degrees Cmin(-1). The Fourier transform infrared analysis of the biofuel indicates the functional groups such as alkanes, alkenes, alkynes, and amines. The composition of the liquid product was analyzed using gas chromatography-mass spectrometry and found that the main constituents were oleanitrile, n-octadecane, 2-tridecanone, heptadecanenitrile, tetradecane, and 2-nonadecanone. The obtained liquid product can be used as a valuable chemical feedstock. The physical properties of the biofuel obtained were close to that of petroleum fractions. The pyrolysis char can be used as an adsorbent as well as a solid fuel due to its high calorific value.
