Mobilizing mine lands for biobased decarbonization strategies
Biofuels, Bioproducts and Biorefining, EarlyView.Abstract Over 163 000 ha of mine lands in Pennsylvania (PA) have the potential to produce willow as a feedstock for renewable energy generation. Each year these lands could produce between 454 000 and 907 000 dry Mg of willow, which can be a feedstock for bioenergy (i.e., biopower) with carbon capture and sequestration (BECCS) or sustainable aviation ...

An Overview of the Chinese UCG Program
Data Science Journal, 2007 Coal is the dominant source of energy in China, but about 50% of the coal resource is left underground unmined. Because of this, the "long-tunnel, large section, two-stage" Underground Coal Gasification (UCG) technology has been put forward, and the UCG ...

Catalytic pyrolysis characteristics of simulated seawater in lean coal
矿业科学学报, 2020 In the underground catalytic gasification process of lean coal, the solid catalyst cannot be used and recovered, so it is necessary to develop an inexpensive liquid catalyst.In order to explore the feasibility of seawater as a cheap gasification agent ...

Investigation of A Biomass Gasification System Based on Energy and Exergy Analysis [PDF]
arXiv, 2022 Biomass gasification procedure is a very complex process and it is influenced by many physical and chemical factors such as biomass gasification temperature and gasifier type. Thermodynamic assessment methodology based on the energy and exergy analysis can be used to evaluate the system performance and environmental impacts.
