Renewable fuels cannot be evaluated clearly as a part of sustainability from their air pollution point of view. A comparison test series have been conducted and from their results external cost has been calculated. Three different fuels and their controlled blends have been investigated, which are the fossil diesel, conventional, standardized biodiesel, and a new type, so called TBK-biodiesel. Fuels have been investigated in a bus Diesel-engine, which operated in steady state points. Air pollution components like CO2, CO, HC, NOx and particulate have been taken into consideration for the calculation. The calculation method is a self-made one. On the basis of the results it can be stated that the overall external costs are higher in all cases of engine operating if renewable fuel is blended in the tested fuel.

Near Future

Global total petroleum deficit and environmental concern on the emissions issues concerning pure diesel had started a technological race in producing alternative sources of energy which includes renewable fuel. Among the developed renewable fuels is the biodiesel which is a type of fuel derived from various sources of vegetable plants and waste fuels. Various biodiesels have been engineered to beat par to or even perhaps, a leap better in term of performance topure diesel. In short,biodiesel has shown a promising sign as the best candidate in overcoming total dependent on petroleum-derived fuel.This paper gives review on various tests and experiments conducted on biodiesel in order to highlight the potentials preserved by the fuel and to further endorse for a more mass usage of biodiesel and simultaneously for Malaysia to be a potential global producer of biodiesel fuels in the near future.

High Production Cost

In lieu of rising crude oil prices, exhaustion of petroleum feed stocks and environmental challenges, only renewable fuels have the potential to match the energy requirements of the future. Among the various renewable fuels, butanol has recently gained a lot of attention because of its advantages over other biofuels. Its microbial production by clostridia through ABE fermentation is being explored for improved yield and cost effectiveness. Using lignocellulosic wastes successfully for butanol production through ABE fermentation is a major breakthrough to deal with the future energy crisis. Genetic engineering of microbes to increase the carbon and redox balance, cell recycling, media optimization, mathematical modelling and tolerance improvement strategies are being attempted to overcome the hurdles of high production cost, by products formation leading to low yield and product toxicity. Along with genetic engineering major research is cantered on heterologous host engineering for improved butanol production and tolerance. This review highlights the recent advances in improving yield and tolerance to butanol in both Clostridial and heterologous hosts from genetic engineering and fermentation methodology aspects.  Int.

Operating Temperature Range

Plasma science has attracted the interest of researchers in various disciplines since the 1990s. This continuously evolving field has spawned investigations into several applications, including industrial sterilization, pollution control, polymer science, food safety and biomedicine. nonthermal plasma (NTP) can promote the occurrence of chemical reactions in a lower operating temperature range, condition in which, in a conventional process, a catalyst is generally not active. The aim, when using NTP, is to selectively transfer electrical energy to the electrons, generating free radicals through collisions and promoting the desired chemical changes without spending energy in heating the system. Therefore, NTP can be used in various fields, such as NOx removal from exhaust gases, soot removal from diesel engine exhaust, volatile organic compound (VOC) decomposition, industrial applications, such as ammonia production or methanation reaction (Sabatier reaction). The combination of NTP technology with catalysts is a promising option to improve selectivity and efficiency in some chemical processes. In this review, recent advances in selected nonthermal plasma assisted solid–gas processes are introduced, and the attention was mainly focused on the use of the dielectric barrier discharge (DBD) reactors.
