19. oxide + calcium phosphate

Kouzu , Yamanaka , Hidaka , Tsunomori , Heterogeneous catalysis of calcium oxide used for transesterification of soybean oil with refluxing methanol, , Year: 2009, Volume: 355, Page: 94-99. DOI:

Based on the results of research conducted, it can be concluded that the minimum temperature shell decomposited to obtain Calcium oxide was 800C. The higher decomposition temperature used will improve the crystallinity of CaOas shown on the XRD diffractogram. The formation of CaOwas also supported by FTIR spectra in the area around 500 cm−1 which indicate the presence of Ca-O vibration. It is confirmed by the XRF data showing the percentage of CaO in the samples > 99 %. The maximum biodiesel yield was 82.25% which was produced in the transesterification reaction using catalyst CaO from shell of calcination at 900C for 10 h, under reaction conditions of catalyst loading of 3 wt.%, methanol to oil ratio of 15:1, reaction time of 3 h and temperature of 60 C.

The catalyst used for producing biodiesel in this study was derived from blood cokle shells () calcined at 800C and 900C for 10 hours. Transesterification was done using basic materials of waste cooking oil (WCO) and methanol. Theyield of biodiesel produced here can be seen in Figure . Figure a shows the effect of reaction time on the biodiesel yield. It can be seen from the figure that the yield of biodiesel increased with increasing reaction time. The longer the reaction time of transesterificationthen the more the opportunity of reactant molecules to collide, so the yield of biodiesel results increased. The optimum biodiesel resultwas obtained at a reaction time of 3 h, and a longer time the yield will decline. This is because in the early stages of the transesterification reaction, the biodiesel production took place rapidly and then the rate declined until it reaches equilibrium at the reaction time of 3 hours. If reaction time is too long it will result in the formation of glycerol and emulsion in the product, increasing the viscosity and affect the purity of biodiesel. Maximum yield biodiesel synthesized using the catalyst calcination at 800C is 79.28 %. This resultis lower than the biodiesel results obtained with the use of catalyst calcination at 900C for 10 h (82.25%). The low biodiesel obtained using catalyst calcined at 800C is due to incomplete decomposition of CaCO3 to CO2 and CaO.

Gasification of dry palm oil empty fruit bunch (EFB), by using a temperature-programmed instrument was performed to determine the amount of synthesis gas produced. Dry and finely crushed EFB was pre-mixed with calcium oxide. Temperature-programmed gasification (TPG) was done at temperature from 50°C - 550°C and also from 50°C - 700°C using 5% oxygen in He. Both experiments were held for 1hr at the final temperature. The products were monitored using an online mass spectrometer. Major products detected from this reaction were H2, CO, CO2 and CH4. The effect of calcium oxide amount (CaO: EFB ratio) was also investigated. A very significant increase of H2 and CO was observed when nano-sized calcium oxide was used as catalyst compared to bulk one. Reaction at 700°C using nano-sized CaO reduces the production of carbon dioxide during gasification. The characteristics of the catalyst used were analyzed by using XRD and XPS show some significant changes from CaO to CaCO3.

Synthesis of Nitric Oxide - University of Reading

AB - The modification of surface features such as nano-morphology/topography and chemistry have been employed in the attempt to design titanium oxide surfaces able to overcome the current dental implants failures. The main goal of this study is the synthesis of bone-like structured titanium dioxide (TiO2) nanotubes enriched with Calcium (Ca) and Phosphorous (P) able to enhance osteoblastic cell functions and, simultaneously, display an improved corrosion behavior. To achieve the main goal, TiO2 nanotubes were synthetized and doped with Ca and P by means of a novel methodology which relied, firstly, on the synthesis of TiO2 nanotubes by anodization of titanium in an organic electrolyte followed by reverse polarization and/or anodization, in an aqueous electrolyte. Results show that hydrophilic bone-like structured TiO2 nanotubes were successfully synthesized presenting a highly ordered nano-morphology characterized by non-uniform diameters. The chemical analysis of such nanotubes confirmed the presence of CaCO3, Ca3(PO4)2, CaHPO4 and CaO compounds. The nanotube surfaces submitted to reverse polarization, presented an improved cell adhesion and proliferation compared to smooth titanium. Furthermore, these surfaces displayed a significantly lower passive current in artificial saliva, and so, potential to minimize their bio-degradation through corrosion processes. This study addresses a very simple and promising multidisciplinary approach bringing new insights for the development of novel methodologies to improve the outcome of osseointegrated implants.

Preparation and properties of calcium oxide from …

The determination of chemical composition of catalyst was performed using X-ray flourescense (XRF) and the results are shown in Table 1. It can be seen from the table that the majorities composition of the catalyst was calcium oxide (CaO). The table shows the results of quantitatively characterization by XRF in which the chemical composition of calcium oxide (CaO) has the largest percentage by weight with the percentages of CaO obtained were 99.14 % and 99.09 % respectively. Besides CaO, catalyst from this shells also contained small amounts of oxides such as K2O, SrO, Cl2O, Fe2O3 and MnO.
