Title: Fuel Properties of Nigerian Castor seed Oil Biodiesel Authors: Mohammed, Ibrahim ARIS; Musa, Umaru; Onifade, K.R; Aberuagba, F Abstract: This paper presents an explicit account of the fuel properties of biodiesel produced from Nigeria castor seed oil. The oil was first characterized for its physico-chemical properties. This was subsequently followed by transesterification of the castor seed oil with methanol in a laboratory reactor using 1% w/v potassium hydroxide (KOH) catalyst at a temperature of 45 °C, mole ratio of methanol to oil of 6:1 and reaction time of 60 minutes. Standard fuel characterization (ASTM fuel tests) was carried out on the resulting biodiesel. Experimental results shown that optimum of 96% methyl ester yield were obtained at 45 °C with a corresponding purity of 98.06% against the European Union lower limit of 96.5%. The important properties of the biodiesel such as specific gravity, flash point, total sulphur, pour point, kinematic viscosity, cetane number, cloud point and water and sediment values were 0.88, 150 °C, 0.006%, 1 °C, 2.5 mm²/s, 48.32 ± 2, 6 °C and 0.04% vol respectively. These values compared favorably with the ASTM and EN standards for biodiesel. The result validates that Nigeria castor seed oil methyl ester could be used as an alternative to petroleum diesel.

Title: ECONOMIC PERFORMANCE OF ACID AND ALKALINE CATALYST PROCESSES FOR BIODIESEL PRODUCTION FROM ANIMAL FAT Authors: Suleiman, B; Abdulkareem, A.S; Musa, Umaru; Mohammed, I.A; Suleiman, Y.B; Oluwadamilare, S.S Abstract: Several processes have been proposed for biodiesel production, but the ultimate aim of any process is to be economically feasible. The quest to identify the most economically feasible process configuration for biodiesel production from animal fats suggest the use of simulation approach to obtain the necessary data at optimal operating parameters and specified feed and product specifications for economic assessment. Two processes configurations for biodiesel production from virgin and waste animal fat using acid and alkaline catalysts were identified and selected respectively. Acid and alkaline process configurations using both virgin and waste animal fat as feed were simulated to produce biodiesel with minimum purity of 99.9 % using Aspen Hysys version 7.2 at oil feed flow rates of 1.16 kmol/h and 1.19 kmol/h respectively. The raw materials requirement, product flow (desired and undesired), utility consumption and equipment sizes were evaluated from the simulation process. The result of economic analysis of alkaline transesterification of waste fat oil shows that the process has the highest total capital investment of $935 353.67 but yet is the most favoured with highest profit before tax resulting from its higher gross income and low cost of raw materials. Similar observation was made in the acid catalyzed process where the use of waste animal fat had the highest total capital investment of $1 995 507 and the most preferred option with highest net profit of $384 410. Among all the various processes investigated an alkaline process using waste animal fat is the most economical option for biodiesel production capable of handling industrial scale production.

Title: Optimisation of Biodiesel Production from Sandbox (Hura crepitans) Seed Oil Authors: Usman, M.; Adebayo, S.; Aliyu, M.; Dauda, S.M Abstract: Transesterification reaction is the most common method of biodiesel production from fats or vegetable oil. In this research, Sandbox (Hura crepitans) seed oil is used as feedstock extracted by solvent extraction using N- hexane as solvent. The study evaluates properties of the oil for it suitability in biodiesel production, biodiesel yields as it is affected by the reacting conditions such as methano-oil molar ratio, reaction temperature, catalyst concentration and reaction time, the reaction conditions are optimized using a two-step four factor factorial design. Results indicate that the feedstock is suitable for biodiesel production, catalyst concentration and reaction times interaction are the important factors that has greater effect on the yield of ethyl ester. The optimum yield condition for Sandbox (Hura crepitans) were 0.2wt/wt molar ratio, 30oC temperature, 0.4wt% catalyst concentration and 60 min reaction time yielding 93% ethyl ester (biodiesel), and all the measured properties of Sandbox (Hura crepitans) of biodiesel met with ASTM6751 standard exception of high polarization rate and slightly high viscosity that can be normalize by appropriate blending. The result showed that only molar ratio showed a negative effect on the reaction. Hence adhering to the standards for high quality biodiesel and economically cheap production process.

Title: Value-Added Sesame (Sesamum indicum) Seed Candy Quality Prediction Authors: Salihu, O.A.; Olorunsogo, S.T. Abstract: Sesame seed candy is a type of candy that is made by combining sesame seeds and either sugar or honey. These ingredients are then formed into a bar or ball shape through pressing. This study aimed to investigate the effect of storage duration and influence of three packaging material on the quality of value-added sesame seed candy. Sesame seed candy samples were packaged in different materials, including Aluminum Foil Laminated Pouches (AFLP), Low Density Poly Ethylene (LDPE, 400 gauges), High Density Poly Ethylene (HDPE, 700 gauges) and stored for 60 days at room temperature. Proximate analysis, sensory analysis and microbial analysis of the samples were carried out every 5 days. The storability analysis of the sesame seed candies shows that both storage duration and packaging material has influence on the total plate count with p-value less than 0.0001. The longer the duration of storage the more the growth of bacteria. The mold count is only affected by the packaging material. Based on the experimental result, aluminum foil laminated pouches are the best material to package the candy and it will still maintain some of its vital qualities over a period of time.
