In that way, there are plenty of advantages derived from its use, such as higher flash and combustion points. On the other hand, the oxidative stability of these samples is shorter, not complying with the European standards. That is the reason why the use of antioxidants, such as butylated hydroxyanisole (BHA), is vital to comply with the standards and make biodiesel marketable. The aim of this research work was to study the effect of BHA at different concentrations (up to 2000 ppm, depending on the kind of sample) on several biodiesel samples derived from several vegetable oils (rapeseed, seed and fried used oils). The results obtained pointed out the improvement of the induction point for all the samples as BHA concentration increased. Moreover, there was an influence of the raw material composition (concerning fatty acid profile) on the induction point of the biodiesel obtained and the subsequent optimum concentration of BHA. Thus, the fatty acid profile was different depending on the sample, being important the higher amount of methyl linoleate of seed and fried used biodiesel, which implied shorter induction points in these samples. As a consequence, for the latter, higher amounts of BHA (around 1400 ppm) were needed. As a conclusion, all the samples studied showed suitable oxidative stability values (over 8 hours) with the use of BHA (at variable optimum concentrations).","PeriodicalId":250863,"journal":{"name":"2019 International Conference in Engineering Applications (ICEA)","volume":"79 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131818786","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Requirements for safety measures and smart devices, for buildings that affect air pollution, along with construction, industry and transport activities. So technological innovation and energy efficiency objectives, with inclusive and sustainable industrialization, in building envelopes with high energy performance and sustainability, in line with european regulations and Industry 4.0. The methodologies aim at dematerialized technologies, with the use of LED light connected to IoT and in the interaction with IT intelligent systems, with photovoltaic and communicative potential with the user and the city, on HCL principles. In addition to Oled and Pled on organic active components for the electronics industry, inorganic LED semiconductors are highlighted that conquer the market for reliability, durability, light intensity, high efficiency and low price. They become the protagonists of lighting, in intelligent systems of efficient and communicative building envelopes through lighting with the city. The criteria are those of reduction of energy consumption and visual comfort, with the use of engineered functional materials, with high optical and photochromic properties, low voltage and low impact, with a good return on investment costs. Construction strategies using sustainable nanostructured materials with high luminous potential and lightness, for air quality and low energy consumption, towards LEC (Light-emitting electrochemical cell) technologies. The challenge is in the application of intelligent LEDs connected to efficient and sustainable envelope systems with innovative chromatic performances, eco-design, development and in the perspective of circular economy.","PeriodicalId":250863,"journal":{"name":"2019 International Conference in Engineering Applications (ICEA)","volume":"107 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126074425","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
