Necessity and exploitation of fossil fuel products are implacable in serving the needs of humanity despite being a finite and limited resource. To meet the thrust of energy, biofuels derived from varieties of renewable resources are imperative in fulfilling the demand of renewable fuels on a large scale without creating environmental concerns. Biofuels are inevitably the result of the carbon fixation process which stores chemical energy, ultimately reducing the total amount of carbon dioxide. Different kinds of biofuels like bioethanol, biomethanol, biogas, and biodiesel are derived depending on varieties of feedstock materials. Among these, production of biodiesel augments the progression of clean and renewable fuel. In this review, we have discussed the production of biodiesel derived from various feedstock and using several processes like pyrolysis, direct blending, micro-emulsion, and trans-esterification, with critical discussion focussing on increasing biodiesel production using nanocatalysts. Biodiesel production mainly proceeds through homogenous and heterogeneous catalysis via trans-esterification method. The review further discusses the significance of nanocatalyst in heterogeneous catalysis based trans-esterification for large scale biodiesel production. With the advent of nanotechnology, designing and modification of nanocatalyst gives rise to attractive properties such as increased surface area, high thermal stability, and enhanced catalytic activity. The role of nanocatalysts have been extensively studied and investigated in regard to the increased biodiesel production. Along with the modification of nanocatalysts, we have briefly discussed the physico-chemical properties and the role of the optimization parameters as it plays a pivotal role in enhancing the biodiesel production commercially.

用于生物柴油生产的纳米催化剂的制备和优化:概述

尽管化石燃料产品是一种有限和有限的资源,但满足人类需求是不可或缺的。为了满足能源的需求,从各种可再生资源中提取的生物燃料必须在不引起环境问题的前提下满足大规模的可再生燃料需求。生物燃料不可避免地是固碳过程的结果,固碳过程存储化学能,最终减少了二氧化碳的总量。根据原料的种类,衍生出不同种类的生物燃料,例如生物乙醇,生物甲醇,沼气和生物柴油。其中,生物柴油的生产促进了清洁和可再生燃料的发展。在这篇评论中 我们讨论了衍生自各种原料并使用热解,直接共混,微乳液和酯基转移等几种方法的生物柴油的生产,而关键的讨论集中在使用纳米催化剂提高生物柴油的生产上。生物柴油的生产主要通过酯交换法通过均相和异相催化进行。该评论进一步讨论了纳米催化剂在基于异质催化的酯交换反应中对大规模生物柴油生产的重要性。随着纳米技术的出现,纳米催化剂的设计和改性产生了引人注目的特性,例如增加的表面积,高的热稳定性和增强的催化活性。关于增加生物柴油产量的纳米催化剂的作用已被广泛研究和调查。随着纳米催化剂的改性,我们已经简要讨论了理化性质和优化参数的作用,因为它在提高商业化生物柴油生产中起着关键作用。
