Feedstocks for Lignocellulosic Biofuel Production

What feedstocks are used for lignocellulosic biofuel production? Many different feedstocks can be used for biofuel production. If the process route consists of gasification/pyrolysis followed by a Fisher-Tropsch process, most feedstocks behave similarly. However, if the enzymatic route followed by fermentation is used, each feedstock behaves differently. Most require pre-treatment prior to hydrolysis. Pre-treatment methods…
