The energy content of Rose multiflora 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 Rose multiflora biomass of control group contains 53.53% of carbon, 7.19% of hydrogen and 0.04% of sulfur; laser stimulated (3times/3sec) group of Rose multiflora biomass contains 53.11% of carbon, 7.22% of hydrogen and 0.04% of sulfur; and laser stimulated (3times/9sec) group of Rose multiflora 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 Rose multiflora biomass is more reactive to combustion as compared to municipal solid waste (MSW). Moreover, pyrolysis and gasification can be used to convert Rose multiflora biomass to liquid or gaseous fuel. This paper also presents analysis of chemical properties, surface area analysis and concentration of Ni/SiO2 and Ni/SiO2 with K2O as promoter for catalytic cracking of tar and enhancing bio-yield production from technologies such as pyrolysis and gasification of biomass. http://pubs.sciepub.com/wjee/3/2/5/wjee-3-2-5.pdf laser biotechnology rose multiflora biomass catalyst pyrolysis gasification energy
