“…3). One can imagine that the compartments grow following the same mechanism as normal tubes, and the growth termination occurs as the catalyst particles are wrapped by graphene shells completely [25], [26], [27] and [28]. Wang and co-workers [12] have discussed the growth and formation of individual CN x nanobell, which is morphologically analogous to some compartment units of the type II nanotubes.…”

In the presence of catalysts, carbon nanotubes (CNTs) can efficiently grow in the environment generated by the rapid decomposition of normal explosives. Controlling the reaction parameters of a mixture of picric acid (PA) with cobalt acetate and paraffin can lead to a welldefined morphology of CNTs. The formation of bamboo-shape tubes is favorable at relatively high Co(AC) 2 /PA and paraffin/PA ratios. It is found that the bamboo-shape tubes are different in morphology and structure and can be categorized roughly into two types, according to the participation of the catalyst nanoparticles. The formation of the two types is discussed.

Abstract.A process of bio-methanol from biogas was studied by modifying kinetic model of reaction's Richardson and Paripatyadar comparing with laboratory data. Bio-methanol process consists of 2 steps: reforming reaction (at atmospheric pressure, temperature 500 -750 o C) and methanol synthesis (at constant pressure 40 bar, temperature 140 -280 o C). The reaction model of each step was individual simulated. Next both steps were integrated, then they were simulated using ASPEN PLUS software. This work investigated the optimum operating condition and predicted result of both reactions. The developing model was obtained, then it was applied for ten thousand liters per day of methanol. The simulation result received from reforming reaction showed increasing temperature effect to rising in CH4 and CO2 conversion and relating with laboratory result. The optimum condition of methanol synthesis is temperature 200 o C under constant pressure 40 bar.
