Project Title #1: Synthesis of magnetic nanoparticle via Microwave-Induced Hydrothermal Carbonization of Empty fruit bunch for Dielectric Material.

Summary

Since last few decades, biomass has gained much attention as a renewable and sustainable future energy because of sharp depletion and unbalanced market prices of fossil fuels, and environmental issues related to petroleum fuels. There are different technologies available to convert biomass into biofuels including solid fuels (biochar/hydrochar), liquid fuels (bio-oil, methanol, ethanol) and gas fuels (hydrogen and synthetic gas) respectively. Hydrothermal carbonization (HTC) thermally converts various biomass feedstocks to a high carbon containing and smokeless solid fuel called hydrochar. Hydrochar production from industrial or agricultural wastes serves a double purpose: utilizing unwanted residues and obtaining hydrochar product. Recently, researchers focus on improving the reaction conditions and targeted products by using catalyst or applying new heating methods such as microwave heating. The advantage of microwave in material processing is mainly attributed to a homogenous, selective and fast heat that significantly reduces processing time and cost . Furthermore, the microwave heating provides suitable conditions for obtaining new products. Despite the widespread use of microwave heating technology for material processing, its use for promoting HTC of biomass has not been explored. Thus, the main objective of this study is to convert agricultural waste biomass such as rice husk to useful material known as hydrochar via microwave HTC process. Further, the process parameters such as microwave power, radiation time and catalyst ratio of microwave HTC was investigating for high yield of hydrochar from rice husk. Moreover, the chemical, structural and thermal properties of hydrochar will be studied.

Project Title #2: Synthesis, Characterization and Chromatographic Studies on Composite Materials. 

Summary

Water pollution caused by heavy toxic metal ions/dyes from various industrial effluents has gained a great world wide attention. A number of regulation agencies have taken concern to restrict their untreated discharge into public severs, rivers, sea and on land. Therefore, the detection, determination, separation and removal of heavy metal ions/dyes are very important due to their toxic effects on water, posing serious hazards not only to humans, but also potentially unacceptable ecological risks to plants, animals and microorganisms. The chromatographic techniques like ion-exchange, adsoption and thin layer chromatography are well know for the identification, separation and removal of heavy metals/dyes owing to their inexpensive, simple and versatile nature. Apart from the various materials used in chromatographic studies, the use of organic-inorganic type composite materials are advantageous to overcome the limitations associated with inorganic and organic materials. There are several routes for the preparation of these materials, but probably the most prominent one is the incorporation of inorganic building blocks in organic polymers by sol-gel process.

Project Title #3: Design of Integrated Pollution Treatment for Palm Oil Mill

Summary

Major pollutions from a palm oil mill consist of wastewater, greenhouse gases and solid wastes. While solid wastes can be processed into organic fertilizers, an effective treatment for the wastewater and greenhouse gas pollutions remains unavailable. Presently, both wastewater and greenhouse gas pollutions still represent a major environmental issue and threat to the sustainability of palm oil mill operation in particular and palm oil industry in general. The goal of this research project is to design a novel integrated treatment system which can: (1) reduce greenhouse gases (both CO2 and methane) emission by at least 90% from its current level, (2) increase the discharged wastewater quality by two-fold, (3) generate electricity, and (4) produce biodiesel. Several advanced technologies will be integrated to build an advanced treatment system.
