High-density polyethylene (HDPE) was converted to a mixed of lower and higher hydrocarbons over micro (ZSM-11 zeolite with MEL structure) and mesoporous (MCM-41) modified materials. The main liquid hydrocarbons (LHC) were: ...

Concrete materials subjected to long term exposures to high temperatures suffer severe degradations in its mechanical properties (cohesion, friction, strength and stiffness) and changes in their failure mechanisms. These ...

Increasing awareness of environmental protection has made both governments and the industry aim for lowering carbon dioxide emissions. For the transport industry this means increasing engine efficiency, replacing fossil ...

In this thesis, the main physical and chemical characteristics of sugarcane bagasse and poplar wood submitted to a thermo-chemical torrefaction process were studied. The materials were dried at a temperature of 105°C for ...

This study aimed to evaluate the effects of glycerol inclusion levels in the fermentation of different carbohydrates and diets for ruminal microflora through the technique of in vitro gas production. The glycerine inclusion ...
