“…Biodiesel is an energy conversion product made from animal fat and vegetable oil through the trans-esterification process. Several researchers have used plants and their products to generate energy such as rubber seed (Jose et al, 2011), Rubber seed oil (Dhawane et al, 2017), oil palm biomass (Bhatia et al, 2017), Wilson's Dogwood , Brassica napus seed oil (Anwar et al, 2017), Koelreuteria integrifolia oil , jatropha oil (Nisar et al, 2017), castor oil (Baskar and Soumiya, 2016), Eruca sativa (Mumtaz et al, 2016) and Pongamia biodiesel as fuel (Perumal and Ilangkumaran, 2017). But, the production of bio-diesel from lignocellulosic biomass is not suitable due to low oil contents.…”

Abstract. Lignocellulosic biomass is one of the abundant renewable bioresources on earth. Its chemical composition, i.e., lignin hinders ethanol production and commercialization. Pretreatment processes are vital for efficient separation of the complex interlinked components and enhance the availability of every component, i.e., cellulose and hemicellulose. However, for the bioethanol production, a major barrier is the removal of strong lignin component which is highly resistant to solubilization and a major inhibitor for hydrolysis of cellulose and hemicellulose. Pretreatment of biomass is necessary to make it susceptible to microorganisms, enzymes, and pathogens. Consequently, for the ethanol production, pretreatment of lignocellulosic biomass process is very costly. The initial pretreatment approaches include physical, physicochemical and biological methods. It found out that; pretreatment methods have a significant impact on efficient production of ethanol from biomass. However, extensive research is still necessary for the development of new and more efficient pretreatment processes for conversion of lignocellulosic biomass to ethanol. Present review article presents recent development on lignocellulose biomass pretreatment. We discussed the different pretreatment methods along advantages, disadvantages, and challenges for bioethanol production. This review includes benefits and drawbacks and chemical, physical, physiochemical and biological pretreatment along with existing problems. For the production of ethanol, this review will help researchers regarding selection, development and further planning of pretreatment for different lignocellulosic residues.

I S S N 2321-807XV o l u m e 12 N u m b e r 12 J o u r n a l o f A d v a n c e s i n C h e m i s t r y Transesterification of Waste Cooking Oil Catalysed by Crystalline Copper Doped Zinc Oxide Nanocatalyst AbstractBiodiesel has its unique position in the field of renewable energy as alternate fuel to diesel due to fuel price, energy requirement and petroleum crisis. In this study, biodiesel was produced from Waste Cooking Oil (WCO) using Copper doped Zinc Oxide (CZO) nanocatalysts. The synthesized Copper doped Zinc Oxide nanocatalysts were characterized by X-Ray Diffraction (XRD) and High Resolution Transmission Electron Microscope (HRTEM). Design of experiment was framed using Taguchi method to limit the experiments and to find the optimum reaction conditions. The effect of process parameters such as oil-to-methanol ratio (O/M), catalyst type, catalyst concentration, temperature and time on the transesterification reactions using characterized Copper doped Zinc Oxide nanocatalyst were investigated. The 4% (weight /weight) nanocatalyst concentration, 1:5 Oil to methanol molar ratio at 60°C temperature and 40 minutes of reaction time were found to be optimum, in which the maximum biodiesel yield of 98 % (w/w) was obtained. Hence it was determined that nanocatalysts exhibited good catalytic activities on biodiesel production from Waste Cooking Oil (WCO). Keywords:Biodiesel, Waste Cooking Oil, Copper doped Zinc Oxide, Transesterification. IntroductionFossil fuels such as petroleum, coal and natural gas are the major sources of increased pollution level. Studieshave shown that biodiesel being less polluting, non-toxic and biodegradable; it can be used directly in most diesel engines without much engine modifications. Biodiesel is commonly produced by transesterification of lipids, animal fats, grease and waste cooking oils [1,2,3,4,5,6,7,8,9,10,11,12,13].Catalyst plays an important role in transesterification reactions. Homogeneous catalysts result in the formation of soap which makes more complication in the reaction and also in the product separation. Heterogeneous catalysts has its own benefits such as ease of separation, easy recovery and can potentially be re-used. Finally, all these benefits leads to a reduced production cost [1,2,3,6]. Due to the nanodimension and morphological structure, the nanocatalyst composites provides higher catalytic activity [14,15]. This research work aims at conversion of WCO into biodiesel using the transesterification process with CZO nanocomposite as heterogeneous catalysts. Since nano particles have a large surface-to-volume ratio compared to bulk materials, they are attractive to use as catalysts for the transesterification reactions. Materials and methods MaterialsCupric sulphate, Zinc sulphate, Sodium carbonate were the chemicals used for synthesizing nanocatalyst. Methanol was used for transesterification reactions. All chemicals were of analytical grade purchased from Merck, India. Transesterification was carried out using Waste Cooking Oil, Copper doped Zinc Oxide nanoca...
