Selected Fuel Properties of Alcohol and Rapeseed Oil Blends
(Molecular Diversity Preservation International (MDPI), 2020-07-25)
- article
The alcohols ethanol and 1-butanol are interesting options as blending components for renewable fuels. We studied whether it is possible to mix these alcohols with a little refined material, rapeseed oil, to obtain stable ...
Pyrolysis treatment of nonmetal fraction of waste printed circuit boards : Focusing on the fate of bromine
(SAGE Publications, 2020-01-06)
- article
Advanced thermal treatment of electronic waste offers advantages of volume reduction and energy recovery. In this work, the pyrolysis behaviour of nonmetallic fractions of waste printed circuit boards was studied. The fate ...
An economic study of combined heat and power plants in district heat production
(Elsevier, 2020-11-25)
- article
Combined heat and power plants are playing an essential role in Finland to reduce carbon dioxide emissions in district heat production. Some of the existing district heat producers need to adopt renewable energy sources ...
Downhole electric heater with high heating efficiency for oil shale exploitation based on a double-shell structure
(Elsevier, 2020-11-15)
- article
To improve the heating efficiency of the downhole electric heaters used in oil shale exploitation, double-shell downhole electric heaters with continuous helical baffles (DS-DEHs) were developed in this study. These heaters ...
Emissions from a medium-duty crdi engine fuelled with diesel : biodiesel blends
(Silesian University of Technology, 2021-03-15)
- article
In the present work, biofuels produced from different raw fatty materials have been proposed as a dominant fuel component in biodiesel–diesel fuel blends. Biofuels were produced from pork lard and rapeseed oil by alkali ...
Kinetics and thermodynamics evaluation of carbon dioxide enhanced oil shale pyrolysis
(Nature Research, 2021-01-12)
- article
The pyrolysis process of oil shale is significantly affected by atmospheric conditions. In this paper, the pyrolysis experiments of oil shale under non-isothermal conditions are carried out using nitrogen and carbon dioxide ...
Hygrothermal Behaviour of Ventilation Cavities in Highly Insulated Envelopes
(EDP Sciences, 2020-06-30)
- article
This article presents long-term experimental studies on the moisture safety in the ventilation cavities of highly insulated (HI) structures. The tested HI-walls had thermal transmittances of 0.11-0.13 W/m2K. A wall with a ...
An application of seasonal borehole thermal energy system in Finland
(Elsevier, 2021-06)
- article
Borehole thermal energy system is an important component of the future low temperature heating networks. Applications of such systems are available around the world presenting various configurations. However, the mobility ...
Energy consumption and product release characteristics evaluation of oil shale non-isothermal pyrolysis based on TG-DSC
(Elsevier, 2020-04-01)
- article
Thermogravimetric-Differential Scanning Calorimetry Analysis (TG-DSC) was applied to study non-isothermal pyrolysis characteristics of oil shales, such as the starting point, stability, pyrolysis interval and product release ...
Influence of lunar semidiurnal tides on groundwater dynamics in estuarine aquifers
(Springer, 2020-03-14)
- article
The influence of lunar semidiurnal tides on coastal groundwater aquifers has been conceptualized for decades. However, a thorough understanding of the impact of tides on groundwater dynamics due to the widely distributed ...
