Structured catalysts based on sepiolite with tailored porosity to remove diesel soot

A Novel FCC Catalyst Based on a Porous Composite Material Synthesized via an In Situ Technique

“…The potential to use sepiolite and its derivatives for applications as a catalyst or catalyst carrier is great. [7][8][9] In this study, to overcome the challenges of using microporous zeolite, a new synthesis technology for the production of a hierarchical zeolite material with controllable hierarchical mesopore using in situ crystallization has been developed. The aim of the current work was to study the synthesis and properties of composite materials that have a wide-pore structure and were obtained using sepiolite, kaolin and pseudoboehmite, and to investigate the catalytic properties of the FCC catalyst prepared from the composite material.…”

Catalytic Activity of Cr2O3/sepiolite in the oxidation of benzyl alcohol

“…Indeed, the H3 typehysteresis was known as typical characteristics for formation of tubular pores in the solids. The specific surface area of such material is about 192 m 2 /g [11,16]. Secondly, TEM image reveals that the 20.4 wt% Cr 2 O 3 /sepiolite is composed of nanofibers.…”

Performance and Stability of Wet-Milled CoAl2O4, Ni/CoAl2O4, and Pt,Ni/CoAl2O4 for Soot Combustion

“…TPO tests under NO/O 2 were conducted in a fixed-bed tubular microreactor (φ = 4 mm; bed length = 70 mm) from 25 to 750 • C with a heating rate of 5 • C/min. 100 mg of catalyst was mixed with 10 mg of soot particles obtained by diesel fuel combustion [71] and stirred with a spatula for 5 min in order to reproduce the loose contact conditions [72]. The mixture was diluted in 1000 mg of SiC (particle size 500 µm), to prevent the formation of hot spots in the catalytic bed, and placed in the center of the tubular microreactor, in contact with a k-type thermocouple used to control the catalyst bed temperature.…”
