ABSTRACT
Bioethanol is by far the most widely used biofuel for transportation worldwide. In the second generation of bioethanol process, lignocellulosic materials, which are abundant and renewable agricultural wastes, are used to produce bioethanol. Establishment of a few commercial facilities for lignocellulose conversion to bioethanol has proven that the main obstacles of this pathway have been overcome, but more eorts are required to develop this technology for a variety of feedstocks and conditions. Ongoing improvement and enhancement of the conversion processes are expected in the future, due to the development of pertinent technologies and sciences. In this chapter, process design, owsheeting, and simulations of bioethanol production from lignocellulosic material through fermentation of sugars from lignocellulose hydrolysis will be discussed, taking into account the fundamentals of chemical engineering, bioprocessing, and similar simulations in the petrochemical industry.
