This paper aims to study decomposition behavior in pyrolytic environment of four lignocellulosic biomass (oil palm shell, oil palm frond, rice husk and paddy straw), and two commercial components of biomass (pure cellulose and lignin), performed in a thermogravimetry analyzer (TGA). The unit which consists of a microbalance and a furnace flowed with 100 cc (STP) min Nitrogen, N2 as inert. Heati...

Lignocellulose is a generic term for describing the main constituents in most plants, namely cellulose, hemicelluloses, and lignin. Lignocellulose is a complex matrix, comprising many different polysaccharides, phenolic polymers and proteins. Cellulose, the major component of cell walls of land plants, is a glucan polysaccharide containing large reservoirs of energy that provide real potential ...

In this research, biosorption efficiency of different agro-wastes was evaluated with rice husk showing maximum biosorption capacity among the selected biosorbents. Optimization of native, SDS-treated and immobilized rice husk adsorption parameters including pH, biosorbent amount, contact time, initial U(VI) concentration and temperature for maximum U(VI) removal was investigated. Maximum biosor...

Barley is the only crop in the Poaceae family with adhering husks at maturity. The color of husk at barely development stage could influence the agronomic traits and malting qualities of grains. A barley mutant with a white husk was discovered from the malting barley cultivar Supi 3 and designated wh (white husk). Morphological changes and the genetics of white husk barley were investigated. Hu...

Until recently no accurate method existed for the quantitative determination of small amounts of tartaric acid in the urine. In 1931 Underhill, Peterman, and Krause (1) reported a calorimetric method based upon the reaction between metavanadates and tartaric acid in which a golden red color results. We are able to report upon its accuracy, for this identical method was developed independently b...

This study is focused on the emission of fixed bed combustor batch operated. Real-time analyser ELPI (electrical low-pressure impactor) system was used to size-segregated particulate matter emission ranging from 40 nm to 10 μm. The results show that total number concentration were 3.4 × 10(3), 1.6 × 10(4), and 1.5 × 10(5) particles/cm(3) · kg(fuel), while total mass of particles were 12.2, 8.0,...

Consolidated bioprocess assures an efficient lignocellulosic conversion to fermentable sugars and subsequently to bioethanol. Such a single-step hydrolysis and anaerobic fermentation was achieved with acclimated Clostridium thermocellum DSM 1313 on different mildly pre-treated agricultural lignocellulosic residues without any additional enzymes/and strains. Acclimation was achieved by serially ...

Extruded pellets were made based on deoiled rice bran and paddy husk using glycerol and cashew nut shell liquid as plasticizer. Effects of incorporation levels of glycerol (GL, 6 to 14 %) and cashew nut shell liquid (CNSL, 6 to 14%) on the physical and functional characteristics of extruded pellets based on deoiled rice bran and paddy husk powders were studied. For A3 samples (12% GL) radial ex...
