A lab-scale downdraft fixed bed reactor was used for the study of sewage sludge, a non-lignocellulosic biomass, torrefaction to enhance the thermochemical properties of sewage sludge. The torrefaction was carried out for a temperature range of 200–350 °C ... see more

In the energy realm there is a pressing need to make decisions in a complex world characterized by biophysical limits. Exergy has been promoted as a preferred means of characterizing the impacts of resource consumption and waste production for the purpose... see more

The object of research is the effect of thermohydraulic irreversibility of energy processes in the cycle of a refrigeration machine using an ozone-safe non-azeotropic mixture as a refrigerant on its energy efficiency. One of the most problematic places du... see more

The internal combustion engine with provoked ignition is a thermal machine that enables obtaining mechanical power from the chemical energy of a fuel. The objective of this work was to evaluate the performance of an internal combustion engine through the ... see more

The raw materials used for the production of biodiesel can be vegetable oil, animal tallow or residual fat. Among them, the use of soybean oil stands out. The present study aims to analyze the exergy efficiency of the soybean oil pretreatment process of a... see more

PV modul performance can be evaluated in terms both energy and exergy based on wavelengths spectrum of the sun method, which take into account the contribution of chemical potential in term photonic energy and exergy corresponding to photonic energy of a ... see more

Abstract. In the last few years there are tendency for cancer study to develop in discovery of new chemical entity (NCE) for new drugs. The needed of NCE based on reality that cancer therapy reaches a resistant level very fast. By developing NCE, multiply... see more
