Biodiesel Production from Waste Cooking Oil Using Different Types of Catalysts

Abstract

The global energy demand is increasing day by day. Fossil fuels such as crude oil, coal and gas are the main source of energy worldwide. However, fossil fuels, which cause acid rain, the greenhouse effect and other such environmental problems, will eventually be depleted, and renewable energy seems to be the most reasonable solution in this regard. Renewable biofuels have significant potential and can meet the world’s current energy demand. One of the important biofuels is biodiesel, and in the future it can replace petroleum. Waste cooking oil was used as a raw material in biodiesel production in order to reduce the production cost of the offered additive. In this study, the aim was to optimize the process parameters for biodiesel production within the acceptable limit values in the literature. Therefore, the molar ratio of methanol to waste cooking oil (9:1–15:1), catalyst concentration (1–5% by weight) and reaction time (60–120 min) were studied for two catalyst types, potassium hydroxide and ion exchange resin Amberlyst 15. The biodiesel obtained with maximum efficiency for each catalyst was also compared with the international biodiesel standards.

“…Proses transesterifikasi ini secara umum dilakukan dengan pelarut metanol dan katalis basa, skema reaksi transesterifikasi dapat dideskripsikan pada Gambar 1. Minyak jelantah direpresentasikan sebagai trigliserida, bereaksi dengan methanol dan katalis basa yaitu NaOH menjadi biodiesel (campuran Fatty Esters) dan gliserin (Ulukardesler, 2023).…”

A Novel PETG Microchannel Reactor for Microwave-Powered Biodiesel Production

“…This is because biodiesel can be produced, utilised, and stored while maintaining the pre-existing petroleum infrastructure of today [3]. Particularly within the context of compression ignition engines, the utilisation of biodiesel is feasible without engine modifications [4]. In addition, biodiesel shares similar physical and chemical properties as fossil diesel, thus eliminating compatibility issues [5].…”

Utilization of iron fillings solid waste for optimum biodiesel production

“…However, the biodiesel production process can be further optimized by leveraging solid wastes as catalysts in a heterogeneously catalyzed process. Heterogeneous catalysis offers distinct advantages over its homogeneous counterpart, including ease of separation, potential for catalyst reuse, and enhanced reaction efficiencies ( Weldeslase et al, 2023 ; Ulukardesler, 2023 ; Veluru et al, 2022 ; Salihu et al, 2021 ; Nixon et al, 2022 ; Hasan and Ratnam, 2022 ; Shaban, 2012 ; Elgharbawy et al, 2021 ; Suzihaque et al, 2022 ; Monika and Pathak, 2023 ; A Alotaibi et al, 2024 ). Several researchers have investigated the use of solid waste as a catalyst in the synthesis of biodiesel.…”
