Exploration of agricultural residue ash as a solid green heterogeneous base catalyst for biodiesel production

Engineering Reports, Volume 5, Issue 1, January 2023., 2023
Transesterification of vegetable oils with homogeneous catalyst for biodiesel synthesis is considered to have a promising future, but it is nonrenewable and hazardous. High production cost, in terms of feedstock oil and catalyst acquisition is one of the major challenges facing the global commercialization of biodiesel.

Comparing Risks for Binomial Reliability Assurance Test Planning

Applied Stochastic Models in Business and Industry, EarlyView.
ABSTRACT Balancing consumer's and producer's risk is an important consideration when planning tests. Instead of focusing on finding a single best test plan, we introduce a general framework to systematically identify a set of binomial test plans by leveraging the inverse relationship between the two risks.

Experimental and numerical engine cycle setup for a dual fuel hydrogen, methane, and hythane with diesel to assess the effect of water injection and nozzle geometry

Environmental Progress &Sustainable Energy, Volume 42, Issue 1, January/February 2023., 2023
Abstract In this study, the potential of gaseous fuels such as hydrogen, methane, and hythane in combination with diesel fuel is assessed in a closed loop thermodynamic framework. An experimental test is conducted with basic diesel fuel and then the model is configured based on the realistic one‐cylinder diesel engine to evaluate the robustness and ...

Biofuel policies used by IEA Bioenergy Task 39 countries: the transition to using the carbon intensity (CI) of biofuels to set targets

Biofuels, Bioproducts and Biorefining, EarlyView.
Abstract The International Energy Agency (IEA) Bioenergy Task 39 countries share a collective ambition to decarbonize their transport sectors, with biofuels and ‘enabling’ policies playing a key role in achieving this goal. ‘Market‐pull’ and ‘technology‐push’ policies have been used successfully, with countries' targets often set using volumetric or ...

The role of Moringa oleifera in the development of alternative biofuels, under the concept of an integral one‐tree biorefinery: A minireview

Biofuels, Bioproducts and Biorefining, EarlyView.
Abstract The Moringa oleifera oil tree is commonly known as the ‘tree of life’ or the ‘miracle tree’ owing to its multiple benefits for humans. The different parts that make up this tree (leaves, seeds and bark) have been used to treat various ailments, diseases and wounds. However, in recent years this tree is being used by the scientific community to

Influence of geometrical manufacturing tolerances on lithium‐ion battery performance

International Journal of Energy Research, Volume 46, Issue 15, Page 23824-23838, December 2022., 2022
The influence of electrode coating thickness, calendaring and electrode cutting tolerance on lithium‐ion battery capacity, energy, resistance and voltage relaxation is investigated through a numerical model. Electrode cutting tolerance has the largest affect upon cell performance characteristics, with calendaring tolerance predominantly affecting the ...
