Experimental results are reported on the (Ca-looping) multicyclic CO2 capture of CaO and nanosilica/CaO composites derived from Ca(OH)2 and nanosilica/Ca(OH)2 dry mixtures subjected in-situ to linear and Constant Rate Thermal Analysis (CRTA) preheating programs in either air or air/CO2 atmospheres. By means of CRTA preheating the rates of the reactions taking place during pretreatment are kept ...

In Ghana, however, ordinary Portland-limestone cement in recent times continues to remain the alternative construction material compared other brands. With rising trend of infrastructural development country undertaken by individuals and real estate companies, there have been categories different brands alongside existing being produced Ghana. The usage lowquality resulting poor bonding materia...

The CaO.SiO2 gel preparation process was carried out based on the Sol-Gel method by mixing CaO Sol with SiO2 sol in a ratio of 1: 5. Starch-based binders variations amount 1%, 2%, 3%, 4%, and 5% were added. dry has resulted. ground, sieved, sintered at temperature 1000oC for 3 hours, then molded into catalyst tablet hydraulic press. 9 mm diameter mold used compression pressure 90 kg/cm2 an aver...

Energy Dispersive X-Ray Fluorescence Technique was used to study the chemical compositions of rice husk in four selected Local Governments, namely-Wudil, Tofa, Kura and Rano Kano State, Nigeria. Rice is edible part paddy one major agricultural wastes that has potential produce composition which can be useful manufacturing industries. The samples were obtained during dry season grounded into pow...

The effect of CaO on the formation of β- and γ-zirconia nanoparticles from α-zirconia was investigated and their stability evaluated via mechanical activation. α-ZrO2+8.5wt%CaO powder was milled for 2-150 hours with ball-to-powder weight ratios (BPWR) of 40:1 and 60:1. Structural evaluations were conducted using X-Ray diffraction and scanning electron microscope (SEM). Thermal analysis wa...

ABSTRAKKabupaten Padang Pariaman memiliki sumber daya pozzolan yang belum termanfaatkan secara optimal. Pozzolan adalah bahan mengandung senyawa silika dan alumina. Untuk pemanfaatan optimal dilakukan analisis karakterisasi potensi sebagai silika. Silika bisa dimanfaatkan untuk baku utama diberbagai industri, seperti industri gelas, keramik, katalis, pertanian pengolahan limbah. mengetahui kual...

In this work the performance of a screening analytical method for Energy Dispersive X-Ray Fluorescence (EDXRF) analysis in terms accuracy and precision was evaluated through rock standard reference materials. The allowed division elements into four groups taking account excitation energies measurement conditions sample. Two materials were used 15 sample replicates prepared analyzed, then statis...

dyke swarms emplacement constitutes one of the conspicuous features of the neoproterozoic arabian-nubian shield (ans) (~950-540ma). based on field investigations, petrographic and geochemical characteristics the dyke swarms in nw sinai (egypt) comprise of mafic (dolerite-trachy-basalt-basalt), intermediate (basaltic-andesite trachy-andesite) and felsic (rhyodacite-rhyolite) varieties. geochemic...

the influence of increasing the sio2/k2o molar ratio on the electrochemical action of a waterbornepotassium silicate zinc-rich coating was investigated by means of electrochemical impedancespectroscopy (eis) and corrosion potential (ecorr) measurements. the eis results showed thatincreasing the sio2/k2o molar ratio in the range of 3.135 to 5 by the addition of nano-sio2 to theresins improved th...
