World Biodiesel Production And Potential

Given the potential impacts of biodiesel production on the edible oils market, Section 3 and 4 assess the potential implications in some detail.

The utilization of biodiesel is not new, since it has been used as a substitute for mineral diesel since early 20th century, but in small quantities. What is new is that from 2005 onwards biodiesel production and use has increased significantly, spearheaded by the EU (mostly in Germany and France), currently responsible for about 80% of the world production. Despite this European dominance, biodiesel production is expected to stabilize in the coming years in the EU, with substantial growth expected in South America (Brazil, Argentina and Colombia) and Asia, as explained in this study.

One of the most serious obstacles to the expansion of the biodiesel industry is the cost of the raw material which can easily represents 60 to over 80% of the total costs, though there are considerable geographical variations depending on the feedstock and local conditions. Therefore, availability of feedstock, cheaply and in large scale, is fundamental to the expansion of this industry. There are two major factors to take into consideration when dealing with feedstocks for biodiesel production. Firstly, is the source, and secondly is composition. In the first case it is important to know if the oil is derived from food on non-food crops; the second consideration is to know the composition of the oil and how appropriate it is as a feedstock (e.g., see Karman, Rowland & Smith, 2008).

Despite the considerable potential of biodiesel, given the growing demand for edible oils and the high cost of the feedstock, this potential may be rather limited in the future unless biodiesel can be extracted from other raw material. Other important constraint is its sustainability, as the extension of land required for biodiesel production is considerable larger than in the case of bioethanol. The extent to which biodiesel may become eventually a global commodity remains uncertain, but it is highly unlikely that it will reach the same level as bioethanol.


Catalytic Conversion Of Glycerol Fine Utilization

Catalytic conversion of glycerol fine Utilization

Biomass energy mainly refers to bio-ethanol, bio-diesel and bio-hydrogen production. Wherein, biodiesel is an alternative to animal fats in the glyceryl group with methanol or ethanol and other lower alcohols obtained long-chain fatty acid alkyl monoester. The main characteristics of biodiesel is low sulfur content, high oxygen content, free of environmental pollution caused by aromatic hydrocarbons; has good low temperature performance; has better lubricating properties; has a good safety performance; with more good combustion properties (high cetane number); diesel engine without modification, can be added directly.

The main byproduct of biodiesel production is glycerin, each producing about 9 kg of biodiesel to obtain 1 kg of crude glycerol byproduct. Purification of the latter subject to filtration, purification, chemical additives and distillation process, if used in food, cosmetics, pharmaceuticals and other areas, it needs to be further bleaching, deodorization, ion exchange to eliminate trace impurities. The cost of crude glycerin made by the pure glycerol is very expensive, how to use new technology and new technology research and development and processing costs low, there is a huge potential for development of crude glycerin, key and guarantee for sustainable development of biodiesel industry.
