Stratified steam explosion energetics

Bioethanol Production from Steam Explosion Pretreated Straw

1.1 Motivation and environmental aspects The combustion of fossil fuels is responsible for 73% of carbon dioxide emissions into the atmosphere and therefore contributes significantly to global warming. Interest in the development of methods to reduce greenhouse gases has increased enormously. In order to control such emissions, many advanced technologies have been developed, which help in reduc...

Mild Steam Explosion and Chemical Pre-treatment of Norway Spruce

The aim of this work is to open up the structure of wood while retaining a large amount of hemicelluloses, in particular (galacto)glucomannans. The effects of pre-treatments on wood meal from spruce (Picea abies) with a reducing agent (NaBH4) combined with steam explosion at very mild conditions were investigated. The effects of steam explosion at 160 °C were studied for various residence times...

Steam explosion pretreatment for enhancing biogas production of Alpine hay

Growing grassland biomass in an extensive way and its subsequent transformation into hay for a further utilization in a biogas-based biorefinery concept could be a solution to increase incomes and maintain the grassland area. In this way, gassland can be promising biomass sources for decentralized energy generation. Efficient biogas production from this lignocellulosic biomass requires a pretre...

Extreme dynamics and energetics of Coulomb explosion of Xe clusters.

Unique features of Coulomb explosion (CE) of many-electron elemental Xe(n) (n = 13-2171) clusters driven by ultraintense and ultrashort near-infrared laser pulses (peak intensities 10(15)-10(20) W cm(-2) and pulse lengths of 10-100 fs) manifest ion dynamics and energetics in the extreme, with ultrafast (5-15 A fs(-1)) velocities and ultrahigh (keV-1 MeV) energies. Relations were established bet...
