EFFECT OF THE FILTRATION WITH BLEACHING EARTHS ON SEVERAL QUALITY PARAMETERS OF THE BIODIESEL OBTAINED FROM AFRICAN PALM OIL

Abstract: In this work, we studied the performance of bleaching earths as removal agents of Total Contamination from samples of Colombian biodiesel obtained from palm oil. The effect of temperature and the dose of three commercial adsorbents were studied on quality p

APPLICATION OF SPECTRAL INVERSION AND FUZZY LOGIC INTERPOLATION IN POST-STACK RESOLUTION ENHANCEMENT ON A SEISMIC VOLUME OF THE COLOMBIAN LLANOS BASIN

Abstract: To improve the stratigraphic interpretation of 3D seismic data it is pursued to increase the vertical resolution by means of a Spectral Inversion (Puryear & Castagna, 2008; Qiu, Junhua, Xiaohui, Hu, & Lei, 2016) and the lateral resolution using a fuzzy logic

AGGREGATE STRUCTURE ANALYSIS OF COLOMBIAN HEAVY CRUDE OIL-DERIVED ASPHALTENES USING SMALL ANGLE X-RAY SCATTERING

Abstract: Small-Angle X-ray Scattering (SAXS) technique was used to characterize the structure of Asphaltene ag - gregates as a function of its concentration in Toluene solutions. Asphaltene concentration ranged from 0.01 to 1% w/v. Solid Asphaltenes were obtained fr

EVALUATION OF COLLOIDAL STABILITY, KINEMATIC VISCOSITY AND FLASH POINT OF B10 DIESEL/BIODIESEL BLENDS USING NANO-STRUCTURED ADDITIVES BASED ON Al2O3 AND OLEIC ACID

Abstract: Alumina nanoparticles were synthesized by sol-gel method and submitted to thermal treatment at 750 and 1000 °C. X-ray diffraction was used to determine crystal formation with sizes up to 280 nm. To achieve stable suspensions, a nano-additive was mixed with th
