Abstract This study investigates the production of diesel fuels by integrated Fischer–Tropsch synthesis over a bifunctional cobalt catalyst consisting component (Co–Al 2 O 3 /SiO ) and zeolite-containing (ZSM-5). The catalytic properties were tested in continuous-flow reactor with stationary bed at 240–250°C, MPa, gas WHSV 1000 h –1 . effects SiO /Al ratio HZSM-5 zeolite on performance, deactiv...

In the present work, B-ZSM-5 zeolite membranes were synthesized on porous tubular α-alumina supports by several subsequence in situ crystallization hydrothermal treatments. The TiO2- Bohmite and ɣ- alumina intermediate layers were applied to improve the lattice matching between zeolite layer and the support. The uniform membrane intermediate layers with low permeation resistance were...

ZSM-5 zeolites are highly silicate materials that have significant application in catalytic processes petrochemistry, especially due to their high selectivity. Most reactions the petrochemical industry acid-catalyzed. The acidic properties of zeolite depend on number acid centers, i.e. presence hydrogen ions, and therefore, this paper possibility reducing sodium content pores with modulus (SiO2...

The elucidation of the selective catalytic reduction mechanisms over state-of-the-art metal-promoted zeolites is essential for nitric oxides removal in automobile and stationary source applications. In this work, H/ZSM-5 catalysts modified with transition metals, including copper, manganese, nickel, were prepared by using an incipient wetness impregnation method evaluated ammonia. Results indic...
