The selectivity toward lower olefins during the methanol-to-olefins conversion over H-SAPO-34 at reaction temperatures between 573 and 773 K has been studied with a combination of operando UV-vis diffuse reflectance spectroscopy and online gas chromatography. It was found that the selectivity toward propylene increases in the temperature range of 573-623 K, while it decreases in the temperature...
One of the main challenges in next decades for chemical industry is valorization low-grade industrial waste streams into valuable materials, as their increasing amount can have a major environmental impact. For example, copper mining industry, flotation tailings be valorized solid acid catalysts, such zeolites. Numerous studies shown that modification zeolites by metal ions has positive effect ...
