Application of oxide nobles metals nano-size as catalysts for biomass conversion reactions. Huynh Thanh Cong, Trương Thanh Ngọc, Nguyên Thuy Đoan Trang, Đao Pham Duy Quang, Ho Son Lam Institute of Applied Materials Science Oxide metals has been nano size synthesized with solution of Me(NO3) 2 macerated in to porous of carbon active and heated in stream inert gas Argon by 550 0 C. The result partition data parsing with X-Ray find the Me(NO3) 2 were converted to format ZnO , PbO , Pb 2 O; CuO and Cu 2 O. Survey samples by SEM show the size of these oxides are from 50-100 nm. The results of analysis of products in gas phase reactions by GC/MS showed isomer reaction can occur on a carrier such as activated carbon or humic acid, but the by product is very high. When the presence of metal oxide nanostructures in the composition of the carrier, content of by- products reduced significantly, from 21% to 2- 4%. Conversion increased while the selectivity also increases. Special case of the Cu- oxide carried in activated carbon were appear out reactions dehydrogenation closed ring. while the carrier is humic acid, not only occurs dehydrogenation round, but also play to promote oxidation reactions in conditions of non oxygen atmosphere. On the base catalyst samples obtained were survey responses of biomass conversion into organic compounds in the vapor phase. Product analysis results, indicating that form a number of organic compounds such as ethanol, acetic acid, Propionic acid. I. BACKGROUND: Coal, oil, natural gas is the material basis for human development for over three hundred years. There may be many ways to explain the formation of coal, oil, gas, but the hypothesis of a buried biomass through geological changes seemed acceptable. Thus, over more billions of years, under the influence of temperature, pressure, biomass was made up of coal, oil and gas reserves. The question for scientists in the world that can promote the transformation of biomass into liquid hydrocarbons in artificial conditions is not? Many works have been published that can be done, however, so far it remains just a dream, because in fact, there was no work is applied in practice. In a review of "History of the bio-oil Hydro processing" published in the journal Energy & Fuels, No. 21 (2007) [1], Douglas C. Elliott has over 73 abstract works in the past 25 years and shows, with many models and technologies of different catalysts-all stop at the pilot form with a capacity of 10-100kg of dry biomass per hour . There are many reasons for the above works cannot get to practice. In our opinion, some following problems may be the main causes: The first reason is the energy to produce liquid hydrocarbons from biomass is greater than energy gained. The second reason is the major component of biomass such as cellulose, hemicellulose, lignin is less soluble in common solvents, so the process of technological transformation of these substances difficult. Some form of ionic solvents can dissolve them but the price is too great and the ability to recover almost no solvent. The third reason is transform biomass into synthesis gas as Methane, Carbon dioxide, Hydrogen for further conversion into liquid hydrocarbons in petrochemical technology that can be done but requires more steps and consuming energy. Hydrogenated vegetable oil to get liquid hydrocarbons is no better solution than using it as current as biodiesel. Bio-ethanol away from starch using biotechnology have been put into production, but affect food security, so now many countries are focusing on building up the industrial chain bio-ethanol production from biomass. Transform biomass into sugars and then into ethanol solution of 10-15% using biotechnology to produce bio-ethanol has been studied and applied in actual production, but this technology requires further evidence 10-15% solution of ethanol distilled into ethanol, 96%, meaning that consume energy. Moreover, not 100% biomass is converted into sugar, but also a massive lie in the form of solid waste. Thus, the study of biomass conversion into liquid hydrocarbons to produce the new generation fuel, called “sun fuel” - still many issues to be addressed. That was our goal. Some initial results of the research is presented in the following experiment. II. EXPERIMELTAL SECTION: . Application of oxide nobles metals nano- size as catalysts for biomass conversion reactions.
