Abstract

Simplicity and environmental friendliness are essential for zeolite synthesis. Here, we report that NaY (NaY-R) zeolite is accomplished over an ambient pressure environment and adopt rice hush ash as silicon source. A floated sealant on zeolite gel may cleverly creates a quasi-sealed environment for reducing water evaporation. Importantly, the catalytic performances of Co loading NaY-R (Co/NaY-R) on a dual-bed catalytic system with ZSM-5 or Beta zeolite are comparable to those of the corresponding catalytic system formed by commercial NaY zeolite (NaY-C). Meanwhile, dual-bed catalytic systems show significantly enhanced selectivity for gasoline ranged hydrocarbons (C_5-11) and isoparaffins compared to the pristine Co/NaY. These results indicate the proposed synthetic protocol can achieve green, safe, and energy-saving synthesis of NaY zeolite, which enriches the insight into designing novel zeolite synthetic route.

期刊介绍： Microporous and Mesoporous Materials covers novel and significant aspects of porous solids classified as either microporous (pore size up to 2 nm) or mesoporous (pore size 2 to 50 nm). The porosity should have a specific impact on the material properties or application. Typical examples are zeolites and zeolite-like materials, pillared materials, clathrasils and clathrates, carbon molecular sieves, ordered mesoporous materials, organic/inorganic porous hybrid materials, or porous metal oxides. Both natural and synthetic porous materials are within the scope of the journal. Topics which are particularly of interest include: All aspects of natural microporous and mesoporous solids The synthesis of crystalline or amorphous porous materials The physico-chemical characterization of microporous and mesoporous solids, especially spectroscopic and microscopic The modification of microporous and mesoporous solids, for example by ion exchange or solid-state reactions All topics related to diffusion of mobile species in the pores of microporous and mesoporous materials Adsorption (and other separation techniques) using microporous or mesoporous adsorbents Catalysis by microporous and mesoporous materials Host/guest interactions Theoretical chemistry and modelling of host/guest interactions All topics related to the application of microporous and mesoporous materials in industrial catalysis, separation technology, environmental protection, electrochemistry, membranes, sensors, optical devices, etc.
