Nano-sized zeolite catalyst having a high silica to alumina ratio

A catalyst includes a zeolite, wherein the zeolite has: a CHA framework; a particle size less than or equal to 100 nanometers; and a silica to alumina mole ratio in the range of about 50:1 to about 150:1. The catalyst can include a metal dopant. The catalyst can be used for purifying a product by flowing a reactant across the catalyst to form the product; and condensing or separating the product. The product can be an olefin or alkenes with an increased carbon chain. The catalyst can be used for selective catalytic reduction of nitrogen oxide or a gas to liquid reaction. A method of producing the catalyst can include selecting the concentration of a crystal growth inhibitor based on the ratio of the silica precursor and an alumina precursor such that the zeolite crystals have a mean particle size less than or equal to 100 nanometers.

Chemical Conversion of Carbon Dioxide and Gaseous Hydrocarbons to Solvents
20210363087 · 2021-11-25 ·

Catalytic chemical conversion of carbon dioxide gas combined with a hydrocarbon gas, comprising natural gas, methane, ethane, propane, butane or pentane, over a transition metal oxide, produces organic solvent products. The process converts oxidized carbon compounds to valued organic products and can reduce or eliminate the carbon footprint of industrial electric power generation industry. Catalytic processes are taught for chemical conversion of oxides of carbon, principally carbon dioxide (formed by combustion of hydrocarbons), to solvent compounds comprising acetone, butanol, pentane and related organic products. The catalysts are transition metal oxides, selected from the group comprising manganese, iron and cobalt or combinations thereof.
