It has been widely accepted worldwide, that the greenhouse effect is by far most challenging threat in new century. Renewable energy adopted to prevent excessive effects, and enhance sustainable development. Malaysia a large amount of biomass residue, which provides country with much needed support foreseeable future. This investigation aims analyze potentials gases from major residues Malaysia...

Submerged cells of the basidiomycete Nidula niveo-tomentosa, a microbial producer of 4-(4-hydroxyphenyl)-butan-2-one, were supplemented with (13)C-labeled L-phenylalanines and with [1-(13)C]glucose. Labeled transformation products were detected by a novel method of analyzing stable isotope-labeled metabolites, gas chromatography (GC) coupled to an atomic emission detector, and by GC-mass spectr...

Limited information is available about the thermodynamic evaluation for biomass gasification process using updraft gasifier. Therefore, to minimize errors, the gasification of dry refinery sludge (DRS) is carried out in adiabatic system at atmospheric pressure under ambient air conditions. The objectives of this paper are to investigate the physical and chemical energy and exergy of product gas...
