Synthesis of transportation fuels from biomass: chemistry, catalysts, and engineering.

Biomass represents an abundant carbon-neutral renewable resource for the production of bioenergy and biomaterials, and its enhanced use would address several societal needs. Advances in genetics, biotechnology, process chemistry, and engineering are leading to a new manufacturing concept for converting renewable biomass to valuable fuels and products, generally referred to as the biorefinery. The integration of agroenergy crops and biorefinery manufacturing technologies offers the potential for the development of sustainable biopower and biomaterials that will lead to a new manufacturing paradigm.

The path forward for biofuels and biomaterials

The Li-S battery has been under intense scrutiny for over two decades, as it offers the possibility of high gravimetric capacities and theoretical energy densities ranging up to a factor of five beyond conventional Li-ion systems. Herein, we report the feasibility to approach such capacities by creating highly ordered interwoven composites. The conductive mesoporous carbon framework precisely constrains sulphur nanofiller growth within its channels and generates essential electrical contact to the insulating sulphur. The structure provides access to Li+ ingress/egress for reactivity with the sulphur, and we speculate that the kinetic inhibition to diffusion within the framework and the sorption properties of the carbon aid in trapping the polysulphides formed during redox. Polymer modification of the carbon surface further provides a chemical gradient that retards diffusion of these large anions out of the electrode, thus facilitating more complete reaction. Reversible capacities up to 1,320 mA h g(-1) are attained. The assembly process is simple and broadly applicable, conceptually providing new opportunities for materials scientists for tailored design that can be extended to many different electrode materials.

Understanding TiO2 photocatalysis: mechanisms and materials.

Highly active Mo catalysts for mixed alcohol synthesis were prepared using Fuji Davison ID silica gel as a carrier. KCl promoted the selectivity to alcohols but reduced CO conversions in particular to hydrocarbons. Productivity of alcohols was largely affected by the reaction conditions. High pressure and short contact time enhanced space-time yield of alcohols, i.e. 420 g (kg-catalyst)−1 h−1 at 5.0 MPa, 573 K, and W/F=1.4 g-catalyst h mol−1. The presence of K effectively prevented the complete reduction of Mo to metal, resulting in the increase in the production of alcohols. The study on addition of ethene and ethanol to synthesis gas revealed that the other roles of K are to retard dehydration of alcohols to alkenes and their hydrogenation to alkanes.
