Catalytic supercritical water gasification: Interaction of sulfur with ZnO and the ruthenium catalyst

Christian Ludwig, Frédéric Vogel, Gaël Peng

Continuous catalytic supercritical water gasification (CSCWG; 400 degrees C, 28 MPa) of microalgal biomass (Chlorella vulgaris) was carried out at the microalgae production site of ZHAW in Wadenswil (Switzerland) non-stop over a period of 100 h. Characteri ...

Geomechanical modelling of CO₂ injection in deep aquifers

Chao Li

CO2 sequestration in deep geological formations is considered as a promising technology to reduce the impact of CO2 on the greenhouse effect. Practically, large-volume of CO2 could be injected into a system that consists of a highly porous host reservoir c ...

Fault reactivation during CO2 sequestration: Effects of well orientation on seismicity and leakage

Victor Vilarrasa Riano

Injection or withdrawal of fluid at depth may trigger felt seismicity. Such human-induced seismicity is a key environmental concern related to the exploitation of natural underground resources. Thus, understanding how to avoid triggering felt earthquakes p ...

Trace gas and aerosol interactions in the fully coupled model of aerosol-chemistry-climate ECHAM5-HAMMOZ: 2. Impact of heterogeneous chemistry on the global aerosol distributions

Isabelle Bey, Luca Pozzoli

We use the ECHAM5-HAMMOZ aerosol-chemistry-climate model to quantify the influence of trace gas–aerosol interactions on the regional and global distributions and optical properties of aerosols for present-day conditions. The model includes fully interactiv ...

Chemistry and climate interactions

Luca Pozzoli

Atmospheric trace gases and aerosols and climate interact in many ways. A quantitative assessment of the influence of trace gases and aerosols on climate can only be achieved if the interactions and feedbacks among these three major components are accounte ...

Alluvionnement des retenues par courants de turbidité

Giovanni De Cesare

Reservoir sedimentation by turbidity currents All lakes created on natural rivers are subjected to reservoir sedimentation. The construction of a dam significantly modifies the flow conditions of natural streams inside and downstream of an artificial lake. ...
