... Utilizing waste lipids to produce renewable diesel has received widespread attention, but the traditional preparation process is limited by rigorous reaction conditions or complex catalytic systems. This study reports a simple acid addition method to improve the conversion of higher fatty acids and/or higher fatty acid esters into long-chain alkanes under mild hydrothermal conditions over commerci ...

Abstract:
... The efficient biomass energy use is a key prerequisite for the implementation of renewable energy development strategies on a regional level. For the highly efficient energy use in the combustion process, it is necessary to properly regulate the process based on its precise description. The paper aim is to evaluate whether dynamic time warping (DTW) methods can be used for this description, as wel ...
... Increased markets for renewable energy feedstocks have led to an expansion of the woody biomass industry in the Southeastern United States. Virginia has had biomass markets for several decades and provides an opportunity to study both producer and market characteristics. A survey was conducted among biomass harvesting business owners in Virginia designed to characterize harvesting operations and m ...

Abstract:
... Hybrid renewable energy systems (HRESs) are a promising tool for reducing emissions in rural areas. Suitable transaction mechanisms and impartial benefit-sharing strategies are the basis for sustainable HRESs. An HRES that focuses on biomass energy comprising three participants, is proposed and a two-stage benefit optimization and sharing model that is based on a reward-punishment-tiered carbon tr ...

Abstract:
... Torrefaction is one of the most important pretreatment processes to improve the quality of biomass as fuel and overcome its disadvantages. Predicting the chemical exergy of torrefied biomass is essential for evaluating and optimizing the performance of biocoal-based power plants. Therefore, the authors report on a wide range of research that has been conducted to accurately measure the chemical ex ...

Abstract:
... Cocoa beans are produced through on-farm processing where residual biomass is discarded, including cocoa pod husks (CPH), cocoa bean shells and cocoa sweatings. CPH represents about 80% of these residues that are generated during the initial cocoa bean processing steps and their disposal occupies large areas, causing social and environmental concerns. In the last decades, the lignocellulosic compo ...

Abstract:
... The complex daily operation and movement of costly machines transporting biomass to bioenergy plants can significantly affect the economic viability of the system. In particular, while a truck should have a closed route from/to the bioenergy plant, a mobile loader may have different departing and returning locations. This study formulated the closed-open routing of mobile machines as a mixed-integ ...

This review article discusses humic substances – specific organic compounds, which are the substantial part of the bioenergy matrix of the food chains of living creatures and the essence of the exchange interaction of those media. The dead organisms (mostly plants) are transformed into humic substances. A prerequisite for creating the monograph was a steady interest in humic substances from humus ...

Abstract:
... Biomass being a renewable source of energy, has emerged as an attractive target for manufacturing valuable products. These possibilities can be explored to meet the current need for degradable plastic, 2,5-furandicarboxylic acid (FDCA). Integration of chemical and biological approaches for direct biomass conversion into FDCA was evaluated in this study. 5-hydroxymethylfurfural (5-HMF) was chemo-ca ...

The synthesized biochars differ in physicochemical properties and surface chemistry influencing ruthenium metal uptake and dispersion and as a consequence its catalytic behaviour. Selectivity exceeding 95% was obse ...

Understanding the roles of nutrient restriction in extracellular electron transfer (EET) and stability of mixed electroactive biofilm is essential in pollutant degradation and bioenergy production. However, the relevant studies are still limited so far. Herein, the effect of nutrient restriction on the EET pathways and stability of mixed electroactive biofilm was explored. It was found that the el ...
