Methyl Chloride Synthesis over Metal Chlorides-Modified Mesoporous Alumina Catalyst

Abstract: Mesoporous alumina has been successfully prepared using sucrose as templates. Mesoporous alumina-based catalysts, neat and impregnated with metal chlorides, were tested for gas phase methyl chloride synthesis from methanol and HCl. The catalysts were characterized with Transmission electron microscope (TEM), N 2-physisorption, X-ray diffraction (XRD), Fourier Transform infrared spectroscopy (FTIR) and X-ray photoelectron spectroscopy (XPS) to identify the relationship between the catalyst characteristics and t… Show more

“…Methane chlorination and methanol hydrochlorination were integrated into the MCM production. Studies show that under the stoichiometric feeding of MeOH and HCl at a temperature of approximately 280–340 °C, the hydrochlorination reaction reached near complete conversion of MeOH and near 100% selectivity of MCM, which is close to the reaction equilibrium. , Therefore, the reaction temperature was specified to be 300 °C.…”

“…It is a methylating agent and is used to introduce a methyl group (−CH 3 ) into other compounds or molecules, such as methyl iodide. The global capacity of methyl chloride is approximately 900,000 tons per year. There are two methods for producing methyl chloride: methane chlorination and hydrochlorination of methanol. Methane chlorination is a radical chain reaction between methane and chlorine, in which four hydrogen atoms of methane are serially replaced by chlorine atoms, generating CH 2 Cl 2 , CHCl 3 , and CCl 4 . , Methane chlorination exhibits limited selectivity for methyl chloride.…”

“…A small shoulder peak at the higher binding energy side at 1023.4 eV is from ZnCl 2 species adhered to the surface of the porous pZPO-NTs. 81 From XPS data, a quantitative measurement of surface composition can also be done after background subtraction of the peak intensities and normalizing with respect to the relative sensitivity factor. 82 The relative sensitivity factor values for the elements Zn 2p, Pt 4f, and O 1s are 5.589, 5.575, and 0.71, respectively, as mentioned in the Kratos instrument database.…”

“…Zn 2p signal mainly comes from Zn 2+ species at a binding energy value of 1022.0 eV. A small shoulder peak at the higher binding energy side at 1023.4 eV is from ZnCl 2 species adhered to the surface of porous pZPO-NTs nanotubes 81 . From XPS data, a quantitative measurement of surface composition can also be done after background subtraction of the peak intensities and normalizing with respect to the relative sensitivity factor 82 .…”
