Polypropylene is a thermoplastic that is widely applied in various automotive industries. Polypropylene is used as a matrix in composite manufacturing because it has the advantages of ease of processing, corrosion resistance, mechanical stiffness, low density, and affordable prices. The advantages of organic fillers (rice husk) are environmentally friendly, low density, and renewable. However, there is a weakness of polypropylene composites using rice husk filler, namely the lack of compatibility between the Polypropylene matrix which is hydrophobic while the filler (rice husk) is hydrophilic,

MAgPP is an effective coupling agent, not only in cellulosic-fibre filled polyolefine composites, but in rice husk flour filled polypropylene composite systems as well. It gives a utilizable construction polymer matrix composite (PMC) material even at a 40 wt.% RH filling degree. The strength and modulus increases by adding the rice husk but the elongation decreases in a non-monotonic way.

Abstract Rice husk is an agricultural waste from the rice milling process that results in environmental problems during its handling. Biomass (such as rice husk) can be transformed into biofuel via pyrolysis. Pyrolysis is a thermal decomposition of organic compounds in biomass at high temperatures in the absence of oxygen. The main difference of pyrolysis liquid compared to fossil fuel is the significant amount of oxygen (O) content instead of its carbon (C) and hydrogen (H). Thus, making pyrolysis liquid has a lower heating value and inferior properties limiting its direct fuel application. O

Abstract:

This study investigated the removal of metal cations (Cd(II)) and metalloid anions (Se(IV)) from their aqueous solution by using agricultural waste (rice husk biochar). Rice husk biochar samples were prepared under 300, 500, and 700 °C pyrolysis conditions and their physicochemical properties were characterized. Aqueous Cd(II) and Se(IV) sorption kinetics and isotherms of rice husk biochar were studied. The results showed that the yield of rice husk biochar decreased from 41.6% to 33.3%, the pH increased from 7.5 to 9.9, and the surface area increased from 64.8 m2/g to 330.0 m2/g as the pyroly

Generally, biomass consists of various amounts of minerals. These minerals influence the biomass characteristics and behavior during their use in a thermochemical process such as pyrolysis. The conversion during pyrolysis and its final product will be affected. This research was carried out to study the impact of washing treatment in water and acid solutions on the rice husk as the raw material for pyrolysis. Also, the effect of acid strength (citric acid as the weak acid while nitric acid as the strong acid) and its concentration (1, 5, and 10 wt.%) was investigated. The results confirmed fro

The thermogravimetric behaviors and the kinetic parameters of uncatalyzed and catalyzed pyrolysis processes of a mixture of powdered raw rice husk (RRH) and its ash (RHA) in the form of pellets were determined by thermogravimetric analysis at three different heating rates, i.e., 5, 10, and 20 K/min, from 303 to 873 K. This research aimed to prove that the rice husk ash has a catalytic effect on rice husk pyrolysis. To investigate the catalytic effect of RHA, rice husk pellets (RHP) with the weight ratio of RRH:ARH of 10:2 were used as the sample. Model-free methods, namely Friedman (FR), Kissi

Biomass based energy is looked upon as a major component of the global renewable energy sector. Biomass not only act as a source of energy but also as a source of chemical products. Pyrolysis is considered as the most effective conversion process because of its wide array of products: biochar, pyrolytic oil and syngas. Thus, when considering biochar as the main product slow pyrolysis is the preferred option. But presence of lignin in the biomass and the working temperature effects the biochar production. Therefore, an experimental study was carried out to optimize char production from rice hus
