This study reports on the delignification of Prosopis juliflora biomass using microwaveassisted alkaline pretreatment. Response surface methodology was employed to analyze the effect of process variables on delignification. Four independent process variables such as microwave irradiation power (270-450 W), microwave irradiation time (3-5 min), alkali concentration (0.75-1.25% wt/vol) and liquid to solid ratio (LSR; 10-20 mL/g) were analyzed. A second-order nonlinear equation was developed to validate the model. The experimental results suggested that all the variables exhibited a similar response. The developed model was statistically valuated using analysis of variance. The optimum conditions determined from the study were as follows: microwave power of 360 W, irradiation time of 4.40 min, alkali concentration of 1.24% wt/vol and LSR of 13.16 mL/g. Maximum delignification of 75.12% was obtained using microwave-assisted alkali pretreatment method. The delignified Prosopis juliflora biomass was characterized using scanning electron microscopy and Fourier transform infrared spectroscopy studies. It was confirmed that microwave-assisted alkali pretreatment for a short duration facilitated maximum removal of lignin from biomass. The present study, therefore, helps in developing a suitable strategy both for satisfying the energy need and management of the exotic weed.

A recent turbulence in the oil market, as well as the ever-decreasing stocks of fossil fuels, has led to growth of interest in various alternative technologies like automotive hybrid vehicles. Despite the rapid increase of markets of hybrid-electric vehicles, their scope for the Gulf Corporation Council region still needs to be explored further. Awareness about benefits of using hybrid-electric vehicles is fast spreading in the Gulf Corporation Council region and this has positive impacts both in terms of consumer satisfaction and reduction of environmental pollutants. The major aim of presented work is to explore the benefits of using hybrid vehicle technology in terms of savings in cost and reduction in greenhouse gas emissions. Emissions savings were found to be in a range of 9–13%. Fuel savings per 100 km were in a range of 8–10 L. The presented work discusses various issues related to background, features, and components of hybrid vehicles. Trends in the design, energy management, component sizing, energy costs, greenhouse emissions, fuel economy, and performance of these vehicles have been analyzed. Further conclusions and recommendations have been made about these issues keeping in focus market trends in the Gulf Corporation Council region.

Munir et al. 8 investigated the production of biodiesel from Capparis spinosa L. seed oil.The properties of the biodiesels depend on the properties of feedstock 9 . To use biodiesel as a fuel, the properties of the biodiesel should comply with biodiesel standards 10 . Biodiesel standards specify the limits for the properties such as density, kinematic viscosity, acid value, iodine value, induction period, cetane number, copper corrosion, calorific value, flash point, cloud point, pour point, cold filter plugging point CFPP , etc. 10 . The American standard ASTM D6751 and European standard EN 14214 are the commonly used biodiesel specifications 10 . Selected properties of different biodiesels from literature are given in Table 1 2 . From Table 1, it is seen that the many biodiesels do not have properties within the limits specified by the standards 10 .One of the approaches to overcome the biodiesel quality issue is to blend different biodiesels such that the resulting biodiesel blend meets the specifications. Moser 11 had adopted this approach and studied the fuel property enhancement of biodiesels through the complementary blending of field pennycress biodiesel, and meadowfoam Abstract: Biodiesel is a viable alternative to petroleum diesel. The properties of the biodiesel depend on the feedstock used to produce it. A significant difference in properties exists between different biodiesels. Therefore, standards for biodiesel fuel had been developed considering many factors such as safe handling, corrosion, ignition quality, stability, cold flow property, and performance. For using biodiesel as fuel, the properties of the biodiesel should be within the limits specified in the standard. Unfortunately, biodiesel produced from many feedstocks does not comply with the specifications for all the properties. To utilize biodiesel with poor quality, biodiesels can be blended so that the properties of the blend comply with the specifications. Determining the optimal biodiesel blend ratio experimentally requires a lot of effort particularly when the number of parameters to be optimized is more and when the number of constituent biodiesels in the blend is more. In this work, the application of non-dominated sorting genetic algorithm to predict optimal blends for different scenarios is demonstrated.
