Abstract:
Analytical pyrolysis was applied to investigate the composition of pyrolysate from seven switchgrass samples differing in cytotype and cutting systems. The content of ash in original samples ranged from 3.2 to 6.4%, cellulose from 31 to 44% , lignin from 3.5 to 8.7%. Pyrolyses were conducted at 700 °C with a microscale pyrolysis apparatus (pyroprobe) and evolved products were analysed by GC-MS (lignin phenols, C5-C6 carbohydrate fragments), GC-MS after trimethylsilylation (levoglucosan) and GC-FID (acetic acid, propionic acid, acetol). Pyrolysates of all the samples were dominated by acetic acid (3.7-5.2%), acetol, 0.9-1.5%, 4-vinylphenol (0.3-1.2%), 4-vinylguaiacol (0.2-0.5%) and levoglucosan (0.2-2%). Yields of total quantified products (18 compounds) ranged from 7 to 11% and tended to increase with increasing lignocellulose and decreasing ash content.
