Abstract

Statement of the Problem: Egypt is a country that faces major environmental issues; ranging from pollution of water bodies to the litter piling up in the streets to the severely polluted air. Egypt is facing an energy crisis because the energy consumption of oil has increased due to the increase in population, while the production has remained stagnant. One of the best ways to tackle this problem is to use renewable energy.  The proposed solution that is capable of partially solving the air pollution, agricultural solid waste and energy crisis problems is the production of fuel from rice straw. The Dutch Avantium Technologies proposed using ethoxymethylfurfural (EMF) as a fuel which is produced from furfural. Furfural is a valuable chemical that has many uses in the fields of renewable energy, medicine, agriculture, paints and dyes, plastics and resins, solvents, and organic products. Methodology & Theoretical Orientation: Six different factors with the potential to affect the furfural production were assessed using ANOVA. From this analysis the optimum operating conditions were evaluated. The reaction kinetics of the formation and subsequent degradation of furfural were determined experimentally. All tests and analyses carried out were done using standard methods. Findings: Production of furfural by acid hydrolysis was found to be possible. Optimum operating conditions for furfural production from rice straw were experimentally determined using analysis of variance to ensure statistical significance. Reaction kinetics were determined to be used in the design of a reactor in a furfural production plant. Conclusion & Significance: Furfural is emerging with increasing value in many fields. The ability to easily produce furfural from rice straw, which would otherwise end up as a solid waste cannot be overstated. This has the double advantage of reducing solid waste and creating a valuable product that can greatly impact the renewable energy sector.
