    Biodiesel fuel (Fatty acid methyl esters: FAME) have lower volatility than petro-diesel fuel due to the larger molecular size of FAME. Recent studies report that the distillation temperature of biodiesel fuel can be lowered by the cross-metathesis reaction with short-chain olefin using ruthenium catalyst. In this study, the effect of cross-metathesis reaction conditions on the distillation characteristics of reformulated biodiesel fuel is investigated to reveal the reaction conditions for fitting the distillation curve of biodiesel fuels to that of petro-diesel fuel. Furthermore, the reactivity of typical biodiesel fuels such as RME (rapeseed oil), SME (soybean oil), and WME (waste cooking oil) for crossmetathesis reaction were examined to reveal the reaction conditions appropriate for their fatty-acid compositions.

    This paper describes how to produce a biodiesel fuel (BDF) from the waste soup of ramen noodles, especially focusing on the recovery process of the oil (triglycerides) from a large amount of waste soup or the oily wastewater disposed of by pouring it down the sink by a ramen restaurant. By combining a semi-transparent bucket (~6 L) with a cock and solvent extraction, it is shown that oil can be recovered easily from 300 or more bowls of ramen noodle waste soup, with an energy profit ratio (EPR) of more than 5.2. The initial cost of the bucket is about 1600 yen, so it has little effect on the price of the BDF produced from the oil in the ramen noodle waste soup, and it is shown that the increase in running cost to produce BDF by this method is about 2.3 yen/L if the rate of recovery of hexane (solvent) is over 99%, which is approximately equivalent to the production cost of waste-cooking-oil BDF production by previously reported methods. Furthermore, in the case of applying the proposed method based on the solvent extraction to the recovery of oil from the oily wastewater disposed of by a ramen noodle restaurant, it is shown that oil can be recovered from the waste soup of ramen noodles just after disposal as well as from the oily wastewater that spent one day in the grease trap. In the former case, EPR is 5.0, and the estimated amount of BDF is greater than 100 L/month for one restaurant. However, in the case of using the oily wastewater from the grease trap, EPR is less than 2.0 because of the reduction of yield of BDF due to a greater oxidation deterioration of the recovered oil, when the alkyl catalyst method is used. Therefore, it is desirable to recover oil from the oily wastewater at the drain pipe just after the sink.

    This paper describes the effect of methanol addition to urea solution for the freezing point depression on the performance of SCR catalyst. In experiments, the effect of methanol addition to urea solution on the NOx reduction performance of SCR catalyst was investigated by using a small-scale catalytic reactor with a simulated exhaust gas. The results show that NOx conversion rate is deteriorated by adding methanol to a reductant even if the mass content of urea in a solution is kept constant.

The purpose of this study was to demonstrate mass production of microalgae in greenhouse photo-bioreactors by aeration with enriched CO2from a diesel engine tri-generation system. The study also demonstrates the capability of algal oil extraction and fuel production processes using a super-heated methanol vapor method with wet microalgal biomass. Approximately 60% of CO2emitted from the diesel engine was absorbed by the monoethanolamine (MEA) system, and one-third of the absorbed CO2was recovered. Cultivation was optimal at 2 vol% CO2for 7.5 hours per day during 2 weeks of the growth phase, after which starvation stress resulting from addition of NaCl and enriched CO2aeration with 10 vol% CO2was induced to increase the oil content. The super-heated methanol vapor method enables effective generation of fatty acid methyl esters from wet microalgae.

    Engine oil dilution can occur because biodiesel fuel (Fatty acid methyl ester: FAME) has lower volatility than petro-diesel fuel. Recently, it was reported that the FAME was broken down to low-molecular structure by cross-metathesis reaction and therefore improving the volatility of FAME. In this study, the improvement of oil dilution was investigated by long-term engine test using the surrogate fuel which simulated FAME after the cross-metathesis reaction. From the experimental result, the dilution ratio using surrogate fuel became about one third in comparison with the case of using FAME only, therefore the oil dilution was improved

    “Drop-in” biofuels have a high potential as an alternative to petro-fuels. Because drop-in biofuels are hydrocarbon fuel, there are no issues related to poor oxidation stability such as in FAME. Diesel fuel which is named “SoladieselRD“ is liquid bio-hydrocarbon and is the hydro-treated oil of micro-algal triglyceride. In this study, the engine performance and exhaust emission characteristics using SoladieselRD were investigated and compared with those using petro-diesel fuel (gas oil). A test was conducted using a single-cylinder, water-cooled, direct-injection diesel engine with a common-rail type high-pressure injection system. From the experimental results, it was clear that the ignition delay of SoladieselRD is shorter than that of petro-diesel, and the trade-off relationship between PM and NOx emissions by SoladieselRD was better than that of gas oil. Therefore, it was concluded that SoladieselRD has a high potential for simultaneously reducing exhaust gas emissions, combustion noise, and specific fuel consumption.
