Abstract
Lignocellulosic biomass is regarded as a promising renewable resource that can be potentially used to provide second-generation biofuels or to produce chemicals. Hydrothermal treatment (HTT) of lignocellulosic biomass has received considerable attention because of its feasibility and efficient generation of valuable products. Recently, much attention has been paid to the studies of using HTT as pretreatment of lignocellulosic biomass for biogas production. These studies show that operational parameters (including temperature, retention time, pressure, solid content, particle size and pH) are crucial for lignocellulose conversion into biogas. Up to now, however, no review could be found on this aspect. In order to optimize the pretreatment process for enhanced biogas production, the above-mentioned operational parameters of HTT are summarized and discussed with respect to the pretreatment of lignocellulosic biomass and their enhancement effects on biogasification. Related studies on hydrothermal treatment of lignin, hemicellulose and cellulose are reviewed. The above parameters adopted in the recent research works for biogas production have been critically addressed. In addition, future research directions are also prospected.
Keywords: Anaerobic digestion, hydrothermal treatment, inhibitory compounds, lignocellulosic biomass, methane production, operation condition.

Catalytic C-H bond activation as a tool for functionalization of heterocycles
The major topic is the functionalization of heterocycles through catalyzed C-H bond activation. The strategies based on C-H activation not only provide straightforward formation of C-C or C-X bonds but, more importantly, allow for the avoidance of pre-functionalization of one or two of the cross-coupling partners. The beneficial impact of ...read more
