Pseudomorphic Reaction: A New Approach to Produce Bulk Mesoporous Silica as Catalyst Support in Methane Reforming
Pseudomorphism is known as a suitable technique for producing mesoscale pore in silica powders keeping their original morphologies. Herein, silica discs with several millimeter dimensions have been prepared using the same method. This method has been utilized through application of pseudomorphism reaction of preshaped bodies by immersion in a solution containing surfactant and swelling re...
متن کاملIron ochre – a pre-catalyst for the cracking of methane
BACKGROUND Iron ochres are gelatinous sludges that can cause problems in terms of water management. In this work, the application of iron ochre obtained from a river has been applied to catalytically crack methane - another potential waste product - into two useful products, hydrogen and a magnetic carbon-containing composite. RESULTS The powder X-ray diffraction (XRD) pattern of the iron och...
متن کاملStability and Thermodynamics of the PtCl2 Type Catalyst for Activating Methane to Methanol: A Computational Study
Stimulated by the report of high-yield, low-temperature catalytic conversion of methane to methyl bisulfate (Periana et al., Science 1998, 280, 560), we studied the relative stability and reaction mechanism of the Pt(NH3)2Cl2 and Pt(bpym)Cl2 complexes in concentrated sulfuric acid. We find that the mechanism involves a series of steps beginning with C-H activation to form an intermediate ion-pa...
متن کاملA novel integrated process for the functionalization of methane and ethane: bromine as mediator
We describe a novel, integrated multi-step process for the partial oxidation of alkanes to alcohols, ethers or olefins using O2 as oxidant. The sequential transformations are (1) alkane bromination to alkyl bromide(s) and HBr, (2) reaction of this mixture with solid metal oxide (MO) to neutralize the HBr and to generate oxygenated products or olefins plus solid metal bromide, and (3) oxidation ...
متن کاملSpectrophotometric determination of hydrazine using bromine and methyl red
Hydrazine has been determined by its oxidation to nitrogen with a known excess of bromine. Bromine in acidic medium bleaches the dye methyl red. A known excess of bromine when treated with hydrazine is reduced to bromide and the unreacted bromine is determined using methyl red. The molar absorptivity is calculated to be 9.95 x10 L molcm. The method obeys Beer’s law in the range 0-6 μg of hydraz...
