The technique of anaerobic fermentation for butanol production have arosen increasing attention, since the butanol as regeneration bioenergy is important to solve the world's energy shortage problem. This study uses a bibliometric approach to quantitatively assess current research trends on anaerobic digestion for butanol, by using the data from the Science Citation Index-Expended database and the Derwent Innovations index of the Web of Science. A metric analysis was made on related literature and patents in these two databases, which was indexed considerly from 2001 to 2011. Results indicated that in recent years there had been a notable growth trend in publication outputs. During this period, USA had the largest number of publications. However, of all the institutes, CHINESE ACAD SCI held primacy over the most publications. The mainstream of anaerobic digestion for butyl alcohol research was in the environmental chemistry, engineering, biochemistry molecular biology related fields. Three journals including Journal of chemical and engineering data, Bioresource Technology, Journal of chromatography, Journal of chemical thermodynamics were the most popular ones in this field. In addition, keyword analysis shows that the process, reactor, pretreatment and co-digestion were the hotpots of the latest 18 years.
