Vol.8 (2018) No. 6 ISSN: 2088-5334 Properties of DMF-fossil Gasoline RON95 Blends in The Consideration as The Alternative Fuel Anh Tuan Hoang # , Danh Chan Nguyen * # Ho Chi Minh city University of Transport, Ho Chi Minh city, Vietnam E-mail: anhtuanhoang1980@gmail.com, tuan.hoang@ut.edu.vn * Ho Chi Minh city University of Transport, Ho Chi Minh city, Vietnam E-mail: chanck06@gmail.com Abstract—The use of endless biomass sources form agricultural by-products for the renewable fuel synthesis has been being considered as the extremely useful works meeting the strict strategies of environment protection. In this work, 2,5-dimethylfuran (DMF) synthesized from available rice straw in Vietnam was mixing with fossil gasoline RON95 to determine and measure the key properties of DMF-gasoline RON95 blends based on corresponding ASTM standards in the consideration as a new alternative fuel for modern gasoline engines. Each 5% volume fraction of DMF was used for mixing purposes to create 21 samples with the change of DMF volume fractions from 0% to 100%. As a result, the linearization of density, octane number, and latent heat of vaporization was conducted; meanwhile, the stoichiometric air/fuel ratio, heating value, and self-ignition temperature of DMF-gasoline RON95 blends were also reported. This work provided the full properties of blends of DMF-gasoline RON95 blends based on experimental results. Achieved results can be used for the next steps to investigate the applicability of DMF-gasoline RON95 blends to practical experiments or simulation studies. Keywords—DMF, fossil gasoline, biomass, physical properties, gasoline engines I. INTRODUCTION Ever-increasing global demand related to fuels for transportation sectors leading to the imbalance of the demand-supply have promoted researchers to look for several renewable resources to offset the shortage of the supply [1][2]. Many years ago, the first generation renewable bio-based fuels produced from edible vegetable oil or seed resulted in the conflict in the food-chain and concerns about the economic-social growth as well as the food security [3][4]. Thus, the current efforts of the study on bioenergy production are to concentrate on utilizing endless and abundant nonfood biomass resources or municipal wastes [5][6]. Among the above-mentioned biomass resources, lignocellulose is known as the potential material for bioenergy production through biological and chemical pathways, which are is illustrated in Figure 1.
