Abstract

In this experiment, nano carbon material was synthesized with nebulized spray pyrolysis method using palm oil. The catalyst used in this study was ferrocene with a concentration of 0.015 g/ml; 0,020 g/ml; and 0.025 g/ml. The catalyst was contacted with carbon precursors using floating catalyst method. The carrier gas used in this study was nitrogen gas at a rate of 1.21 sccm. Nebulized process was conducted for 30 minutes with an operating temperature of 650°C; 700°C; 750°C; 800°C; 850°C; and 900°C. In this study, nano carbon material was synthesized by deposition directly on the walls of the tube / stainless steel reactor so no need a substrate as a growth medium carbon nano. The characteristics of nano carbon material was analyzed by several methods, such as SEM, EDS and XRD. The XRD analysis of carbon sample synthesized at 0.025 g/ml catalyst and all variations of temperature showed the presence of the C (002) and C (100) peak indicated a graphitic structures. From SEM observation, it can be seen that the structure of carbon nano spheres were found at temperature of 700°C and mixtures of nanotubes and nanospheres were established at temperature above 800°C.

Abstract

In an effort to improve energy efficiency of the evaporator station, Falling Film Plate Evaporator (FFPE)can be used as solution. Though it indicated an improved performance of evaporator station there has been aserious problems of hard scales formation. Chemical cleaning with commercial formula wasn’t effectiveenough to remove scale at normal operation period. As interim effort the problems is approach by shorteningoperation cycle of FFPE to 8-10 days to prevent thicker scale formation. Therefore research is needed tolook for an effectives and friendly formula for FFPE scales cleaning. The preliminary results showedthat FFPE scale with working cycle of 8-10 days was thin, less than 1 mm thickness and weight of 2.89mg/cm2. The scale has a soft texture, a bit fragile and blackist brown colour. The KA and KB (Kom - 2)combination was more effective than single one (Kom - 1). The factory trial shows that the performanceof FFPE was better after cleaning than before. After acid cleaning and washing the bottom of plate pack wascleaner.

Abstract

The development of industrial field causes increasing amount of heavy metal ions in the environment. A promising method to deal with the problem above is by utilizing reversible thermosensitive gel as an adsorbent to adsorb heavy metal ions in the environment. The purpose of this research is to develop a reversible thermosensitive gel that able to adsorb heavy metal ions from contaminated water. Copolymergel containing zwitterionic betaine N,N’-dimethyl(acrylamidopropyl) ammonium propane sulfonate (DMAAPS) and thermosensitive N-isopropylacrylamide (NIPAM) copolymer was employed as an adsorbent that able to adsorb and regenerate heavy metal ion in salt solutions. The effect of different ion in various salt solutions and temperature on the adsorption, desorption, and swelling degree of the gel were investigated in this research. The solution used in this experiment are Zn(NO3)2 and Pb(NO3)2 solutions. The gels were synthesized using free radical copolymerization. The synthesized gel showed higher adsorption and desorption ability in Pb(NO3)2 solution than that in Zn(NO3)2 solution. However, gel has a higher value of swelling degree in Zn(NO3)2 solution than that in Pb(NO3)2 solution. Other noticeable result is that swelling degree, desorption, and adsorption ability of the gels decreases in all solution as temperature rises.

Abstract

Spray drying widely applied in industry for drying the material because it has many advantages including capable to produce particle up to nanometer size, having a continuous process, and high purity. The method that we used in this research is Flame Spray Combustor. This research has the objective to synthesize particles of silica from waterglass and determine the effect of pH on particle silica produced. Analysis of SEM, XRD, and BET was conducted to determine the morphology, crystallinity, particle’s size, surface area and pore size of the silica particles produced. Morphology of silica is small spherical and has an amorphous structure. At pH 8 to 10 the size of silica particles increases with increasing pH, and at pH 11 the size decreases. The higher pH, the smaller surface area of silica particles produced. Meanwhile, the greater pH, the greater pore size of silica particles produced.
