The Effect of Calcination Temperature on Metakaolin Characteristic Synthesized from Badau Belitung Kaolin

Abstract

The effect of Metakaolinization on the thermal and physicochemical properties of Badau Belitung kaolin is presented. Calcination of Badau Belitung kaolin indicated that kaolin was transformed to metakaolin at temperature above 500°C. The metakaolin was characterized using X-ray Diffraction (XRD), Fourier Transform Infrared (FT-IR) and Brunauer-Emmett-Teller (BET). The XRD diffraction pattern of the metakaolin was highly amorphous as a result of calcination effect on the raw kaolin. The FTIR spectra of the metakaolin produced showed that the material was thermally stable at temperature range of 500–700°C, whereas the specific surface area values of the raw kaolin and the metakaolin formed were increased with increasing calcination temperature from 500°C to 700°C.

Synthesis and Characterization ZSM-5 Based on Kaolin as a Catalyst for Catalytic Cracking of Heavy Distillate

“…The previous studies have reported the determination of physical-chemical characteristics of "Badau Belitung kaolin" and their dehydroxylation effect during metakaolinization and metakaolinization on the specific surface area (Ulfiati et al, 2020a;Ulfiati et al, 2020b). The current study aims to observe the physicochemical properties and catalytical performance of ZSM-5 catalyst based on kaolin produced.…”

Synthesis and optimization of Ni/Mo-impregnated kaolin-based ZSM-5 as a catalytic hydrocracking catalyst for heavy petroleum distillates

“…16 Furthermore, much effort has been expended to loading Ni and Mo onto the supports of ZSM-5 catalysts in order to boost their catalytic activity. 19 Earlier studies 20,21 evaluated the physical-chemical properties of Badau Belitung kaolin and their dihydroxyl meta-kaolinization on a specic surface area. The physicochemical properties and catalytic performance of the kaolin-based ZSM-5 developed for heavy distillate catalytic cracking were revealed in 2022.…”
