Modification of bayah banten natural zeolite as heterogeneous catalyst in biodiesel production

Abstract

The purpose of this study was to produce a biodiesel through the reaction of waste cooking oil with methanol by using a modifi ed Bayah Banten zeolite as catalyst. This catalyst was produced from its natural from by using potassium hydroxide (KOH) as a reactant in 100 ml of distilled water. The reaction to produce a biodiesel was performed at various temperature and time to get the optimum condition. The advantages of this catalyst were eco-friendly, easily separated after the reaction process, and can be reused as a catalyst. The molar ratio of waste cooking oil and methanol for transesterifi cation process was 1:7. The yield of biodiesel at various optimum temperatures and times is 94% (50 gram of KOH/100ml), 87,8% (75 gram of KOH/100ml), and 86% (100 gram of KOH/100 ml). Biodiesel results were analyzed by GC Ester content and modifi ed catalysts were characterized using XRD, FTIR, and SEM-EDX.

Effect of Temperature and Concentration of Zeolite Catalysts from Geothermal Solid Waste in Biodiesel Production from Used Cooking Oil by Esterification–Transesterification Process

“…The results obtained in this study were better than those of other researchers who used zeolites as catalysts. In a study conducted by Hartono et al [37], using Banten Bayah natural zeolite modified with potassium hydroxide, the yield of biodiesel was 94%. Meanwhile, Al-Jamal et al [38] used zeolite tuff impregnated with KOH for biodiesel production and provided a maximum biodiesel yield of 96.7%.…”

The Effect of Chemical Activation Using Base Solution With Various Concentrations Towards Sarulla Natural Zeolite

“…Natural Zeolite (NZ) is usually formed as a secondary mineral in several geological activities in the Earth's crust. Indonesia has got many sources of natural zeolite which are widely spread across various regions such as Lampung (Elysabeth et al, 2019), Bayah (Hartono et al, 2019), Tasikmalaya (Dewi et al, 2016), Ende-Flores (Noelaka et al, 2018), Malang (Erlynata et al, 2014), Gunung Kidul (Hernawan et al, 2015) as well as in Sarulla -North Tapanuli (Sihombing et al, 2020). NZ is available in large quantities at low-cost exploitation and until today, it has not been fully utilized.…”
