The Influence of Laser Biotechnology on Energetic Value and Chemical Parameters of Rose Multiflora Biomass and Role of Catalysts for bio-energy production from Biomass: Case Study in Krakow-Poland

A study of energy recovery from three groups (control, laser stimulated (3times/3sec) and laser stimulated 3times/9sec) of <i>Rose multiflora</i> biomass after 5 years field experiments was undertaken. The energy content of <i>Rose multiflora</i> biomass control group is 17.574 MJ/kg, laser stimulated (3times/3sec) group is 18.255 MJ/kg and laser stimulated (3times/9sec) group is 17.698 MJ/kg. The elemental composition of the samples was investigated using Eltra CHS 580 analyzer and it shows that the <i>Rose multiflora</i> biomass of control group contains 53.53% of carbon, 7.19% of hydrogen and 0.04% of sulfur; laser stimulated (3times/3sec) group of <i>Rose multiflora</i> biomass contains 53.11% of carbon, 7.22% of hydrogen and 0.04% of sulfur; and laser stimulated (3times/9sec) group of <i>Rose multiflora</i> biomass contains 53.16% of carbon, 7.37% of hydrogen and 0.03% of sulfur. The energy flow (exothermic and endothermic) and thermal degradation analysis were carried out using calorimeter (model: KL-12Mn) and European PN-EN and ASTM standards respectively. It has been observed that <i>Rose multiflora</i> biomass is more reactive to combustion as compared to municipal solid waste (MSW). Moreover, pyrolysis and gasification can be used to convert <i>Rose multiflora</i> biomass to liquid or gaseous fuel. This paper also presents analysis of chemical properties, surface area analysis and concentration of Ni/SiO<SUB>2 </SUB>and Ni/SiO<SUB>2</SUB> with K<SUB>2</SUB>O as promoter for catalytic cracking of tar and enhancing bio-yield production from technologies such as pyrolysis and gasification of biomass.
