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 °C and at a heating rate of 20 °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.
