Abstract: A method for converting natural gas and carbon dioxide into hydrogen and carbon monoxide using a Ni—Al2O3 catalyst. In one embodiment, the method includes using a dual-mode cyclic reactor. Moreover, the disclosed technology relates to a catalyst, its preparation method, and the process of converting natural gas with carbon dioxide to hydrogen (H2) and carbon monoxide (CO). The catalyst is used in a cyclic reactor system process that contains two modes of operation (Mode I and Mode II) and two different feeds (Feed A and Feed B), one per mode of operation. Feed A can be a methane, or methane-rich stream. Feed B is specified to be a carbon dioxide, or carbon dioxide-rich stream.

Abstract: A method for producing carbon nanotubes includes subjecting a plastic material and an acidic zeolite to a pyrolysis reaction so as to form a hydrocarbon compound having 1 to 6 carbon atoms. The acidic zeolite has a molar ratio of SiO2 to Al2O3 ranging from 5.1:1 to 80:1. Another method for producing carbon nanotubes includes subjecting a hydrocarbon compound having 1 to 6 carbon atoms and a catalyst to a catalysis reaction so as to obtain the carbon nanotubes. The catalyst includes a support and a plurality of ferromagnetic nanoparticles supported on the support. The ferromagnetic nanoparticles have an average diameter ranging from 20 nm to 30 nm, and are derived from acetylacetonate of a ferromagnetic transition metal.

Abstract: A method of producing a Se/Biochar-Au—Bi2O3/TiO2 catalyst includes acid treatment of a palm waste with phosphoric acid to form an acid-treated palm waste, carbonizing the acid-treated palm waste to form an acid-treated biochar, and chlorinating acyl groups present on the acid-treated biochar with oxalyl chloride to form a chlorinated biochar. The method may include reacting the chlorinated biochar with an organoselenium compound to form an organoselenium-functionalized biochar and mixing the organoselenium-functionalized biochar with Au-doped Bi2O3/TiO2 particles to form the Se/Biochar-Au—Bi2O3/TiO2 catalyst.
