Abstract:

This research work is on the determination of the properties of palm oil as potential base oil for producing bio based lubricants. The samples analysed were obtained from the open markets in the South West, South East and South South zones of Nigeria. Some of the physical and chemical properties such as viscosity, flash point, pour point, cloud point, specific gravity, acid number, noack volatility and aniline point were analysed. The samples were degummed, neutralised and bleached to remove the red colour (carotene) and gummy materials. The bleached samples were tested to determine the above

Abstract:

The production of biodiesel using vegetables oils is studied. Palm oil and its use for production of biodiesel have been focused. Palm tree is very productive and one of the most profitable for biodiesel production. Among the oilseed crops palm tree produce more oil per hectare. Palm oil has a good availability and a competitive price. The production of palm oil at the industrial plantation level has caused environmental damage. The Roundtable on Sustainable Palm Oil has established principles and criteria in order to certify a sustainable cultivation of the palm oil. The experimental work inv

Abstract:

Oil palm has been considered one of the most favorable oilseeds to biodiesel production in Brazil. The crop has been cultivated in the north and northeast regions under commercial plantations and agroforestry systems. As the oil palm is a perennial crop, it is important to understand how the intensive cultivation affects the dynamic of soil organic matter in the long term. The goal of this work was to determinate the greenhouse gas emissions associated to the main production steps and the changes on soil organic carbon under oil palm plantations. Soil and greenhouse gas samples were collected

Abstract:

This dissertation consists of three closely related essays on upgrading in agro-commodity value chains, which is an important issue for many developing countries that produce and export commodities in mostly unprocessed form. The essays are based on fieldwork in Malaysia and focus on its palm oil, which is the world’s largest oils and fats product by production and export volumes. The first essay examines the suitability of vertical specialisation for participation and upgrading in agro-commodity value chains based on the case of Malaysian palm oil. It uses data from interviews, site visits, a

Abstract:

It is estimated that about 26 million metric tons of oil palm oil residues are produced annually in Malaysia. The oil palm residues contain high ash content, high alkali metals and low lignin content. Ash and alkali metals lead to slagging in a combustion reactor and fouling of surfaces in convective tubes of heat exchangers. Low lignin content leads to disintegration of pellets during pellet handling and storage. This research thesis investigated the pelletization performance and the ash reduction on Empty Fruit Bunches (EFB) and Palm Kernel Shell (PKS) of oil palm residues by two different p

Abstract:

A large part of energy carriers and chemicals of our society come from fossil fuels; due to their critical exploitation and environmental concerns, alternative solutions should be promoted. The goal of this work is to understand the environmental impacts of different supply chains of levulinic acid production. To enable this comparison, a cradle-to-gate LCA was conducted on different kinds of biomasses, under an innovative thermochemical process called Biofine. The study concerns biomass not only of agri-food origin (corn stover, barley straw, wheat straw), but also deriving from the waste co

Abstract:

Energy is a basic requirement for human existence and its consumption increases every year. Currently, most of the energy needs come from conventional fossil fuels, such as gasoline, liquefied petroleum gas, petrodiesel and natural gas. However, the use of fossil fuels has serious environmental problems associated with it. One of the most promising alternative (renewable) energy sources is biodiesel. Usually the production of biodiesel is a catalyzed process, in which alkaline or acid catalysts are used, for the conversion of triglycerides (transesterification reaction) and free
