Investigation on Saprolitic Laterite Ore Reduction Process using Palm Kernel Shell Charcoal: Kinetics and Phase Transformation

نویسندگان

چکیده

The performance and kinetic of saprolitic laterite reduction using palm kernel shell charcoal anthracite were studied. coal represents the conventional high-grade carbon content matter, biomass-based reductant. experiment was conducted at a temperature ranging from 800oC 1000oC. XRD analysis applied to observe phase transformation. For study, two models, namely (1) Jander (2) Ginstling-Brounhstein diffusion model, applied. mineral results indicated that both reductants yield Magnetite Goethite in laterite. best fit model is obtained by with energy activation 33.68 kJ/mol

Xylene removal from dilute solution by palm kernel activated charcoal: Kinetics and equilibrium analysis

Xylene is an aromatic hydrocarbon that is a highly toxic compound. Therefore, it is essential to remove this component from wastewater before discharging it to the environment. In this research work, palm kernel biomass was activated chemically by H3PO4 and synthesized activated charcoal was applied to separate xylene from aqueous media. The prepared activated charcoal was characterized using F...

Removal of heavy metal from industrial wastewater using chitosan coated oil palm shell charcoal

* Corresponding author This research focuses on understanding biosorption process and developing a cost effective technology for treatment of heavy metals-contaminated industrial wastewater. A new composite biosorbent has been prepared by coating chitosan onto acid treated oil palm shell charcoal (AOPSC). Chitosan loading on the AOPSC support is about 21% by weight. The shape of the adsorbent i...

An Experimental Study of Briquetting Process of Torrefied Rubber Seed Kernel and Palm Oil Shell

Torrefaction process of biomass material is essential in converting them into biofuel with improved calorific value and physical strength. However, the production of torrefied biomass is loose, powdery, and nonuniform. One method of upgrading this material to improve their handling and combustion properties is by densification into briquettes of higher density than the original bulk density of ...
