“…Bayah Natural Zeolite are known as zeolite Mordenite (MOR) and Clinoptilolite (HEU) (Ismetulloh et al, 2019). The XRD patterns ( Figure 1) will be compared with the JCPDS (Joint Committee on Powder Diffraction Standards) data according to the International Zeolite Association (IZA) to prove the similarity in zeolite types (Treacy et al, 2001).…”

Biooil is the main product in the pyrolysis process which is expected to be a liquid fuel replacement solution. But the resulting biooil cannot be directly used as a result of high oxygenated compounds, high viscosity, corrosive, and unstable. Addition of activated natural zeolite catalyst to the pyrolysis process is expected to improve the quality of biooil in order to be used as a renewable liquid fuel. The research aims to determine the influence of acid concentrations on zeolite modification to the characteristics of pyrolysis products. Result of catalyst characterization indicates that zeolite activation using acid will increase Si/Al ratio as well as open the surface of previously hindered zeolite. The yield of char produced in this study tends not to undergo significant changes between the catalytic and noncatalytic pyrolysis by 33% wt. Addition of zeolite catalyst in pyrolysis proved to be able to increase the content of phenol and decrease the content of acetic acid in bio-oil by 6% . Meanwhile, yield of CO2 increases by 20% in the use of catalysts due to the release of oxygen in the oxygenate compounds. The results of this study showed that the resulting biooil still does not meet the specifications of liquid fuels but can be utilized as a renewable chemical feedstock.Keywords: pyrolysis; biomass; natural zeolite;modified

“…Penelitian mengenai penentuan karakteristik dan kemampuan adsorpsi amonium (NH4 + ) dengan zeolit alam Bayah yang berasal dari lokasi yang berbeda masih jarang diteliti. Pada penelitian yang telah dilakukan di antaranya mengenai karakterisasi zeolit alam Bayah (6) , modifikasi zeolit alam bayah menggunakan asam dan pengaplikasiannya dalam pengurangan amonium pada kolam ikan bandeng (7) , dan modifikasi zeolit alam Bayah menggunakan basa untuk aplikasi eliminasi di dalam kolam bandeng (8) . Pengetahuan mengenai pengaruh lokasi tambang zeolit dapat memberikan kontribusi untuk pemahaman karakteristik zeolit alam Bayah.…”

Household waste is one of the most significant contributors to wastewater that can pollute the environment, one of which is ammonium pollution. Ammonium pollution can be reduced by natural zeolite by using the adsorption method. This research aims to utilize natural zeolite as an adsorbent that can reduce ammonium levels in wastewater, determine which natural zeolite has the most significant adsorption power from 4 locations, determine natural zeolite characterization of Bayah. This study is also to create a model equilibrium equations and reaction kinetics from the adsorption method. The method used is the adsorption method, X-ray diffraction (XRD), Scanning Electron Microscope (SEM), and Brunauer-Emmett-Teller (BET). This study's results were that natural zeolites location 4 could adsorb 99.25% of ammonium and showed the highest adsorption capacity of ammonium. Characterization using XRD analysis obtained the types of zeolite mordenite, clinoptilolite, quartz, and heulandite. The surface area of Bayah natural zeolite in the 4th location is 46 m2/g. The suitable equilibrium model for the adsorption of ammonium by natural zeolites is the Freundlich model. The most suitable adsorption kinetics model for the adsorption of ammonium by Bayah natural zeolites is the pseudo-first-order model.

Oil palm shell (OPS) constitutes 60% of the waste generated during the processing of palm oil. However, OPS can potentially be converted into energy and chemicals through pyrolysis. The purpose of this study is to determine and analyse the effect of acid treatment time on the characteristics of natural zeolites, which were then applied to oil palm shell pyrolysis. The effect of the acid treatment time on the products of the pyrolysis was also studied. The acid treatment time was varied: 1, 3, and 5 hours. The crystallinity of the natural zeolites was determined by X-ray diffraction (XRD). Solid, liquid and gaseous pyrolysis products were observed. Proximate, ultimate, and heat analysis were performed on the solid product. The liquid product was characterised using gas chromatography-mass spectrometry (GC-MS). Gas Chromatography (GC) was performed to analyse the composition of the gases produced. The results obtained from this study indicate that longer reflux times reduced the crystallinity of the zeolites. The addition of the zeolite catalysts increased the liquid products of pyrolysis from 24.5 wt% over the parent to 24.6–37.1 wt% over the acid-treated natural zeolites. The reduction of oxygenated compounds in bio-oil was observed in the amount of acetic acid and acetone produced. Copyright © 2021 by Authors, Published by BCREC Group.
