“…This is also implied that the FCC catalyst is adverse to decrease the coking formation. The liquid yield is about 48.2 wt% of gasoline and diesel fraction at 650 o C. For Ca 12 Al 7 catalyst, all of the tested parameters (the heavy oil conversion, the yields of coke and gas) are reduced except that the liquid yield when compared to the FCC catalyst at 650 o C.

“…Previous studies found that the base catalyst has advantages of high cracking stability, good hydrothermal properties, high light olefins yield and anti-coking property [10,11]. Furthermore, the base catalysts are widely applied in the reactions of transesterification to produce biodiesel [12] and the coke gasification because of its high reactivity, good production selectivity, and mild reaction conditions [13,14].…”

Abstract. The residue cracking gasification process is intended to convert vacuum residue into light olefins by cracking and co-production the H 2 -rich syngas by gasifying the cracking-generated coke. In this paper, a bifunctional base catalyst is used and tested vacuum residue cracking gasification in a fluidized bed reactor in comparison with the effects over FCC catalyst and SiO 2 . The result shows that higher light olefins yield is produced with Ca 12 Al 7 as the cracking catalyst in comparison with that over the FCC catalyst and SiO 2 . The coke over the Ca 12 Al 7 catalyst is gasified well at 800 o C in steam. The content of H 2 is about 55.5 vol% and with the content of CH 4 is less than 0.2 vol% when compared to 36.6 and 2.4 vol% over the FCC catalyst, respectively.

Solid oxide catalysts derived from various renewable sources have produced significant yield of methyl esters of enhanced purity. These materials are sourced for due to their advantages ranging from low cost, recoverability and reusability, environmental benign-ness, thermal stability and high quality product generation. For a possible greener production process, many researchers in literature reported the use of biomass-derived heterogeneous catalyst in biodiesel synthesis producing high quality pure product. The catalysts were majorly modified through simple physical cost effective and energy saving operations. This paper explores some of these bio-based heterogeneous catalyst used in biodiesel production via transesterification and esterification approach and their performance in FAME yield and conversion. The feedstock consideration which warrant the route selection, various approaches that are adopted in biodiesel production, performance of renewable heterogeneous catalyst and the measures that were adopted to enhance efficiency of the catalyst were considerably highlighted. It is observed that the prospects of organic-based solid catalyst in biodiesel development is a promising enterprise compared to the conventional methods utilizing homogeneous chemical catalyst, which generates wastewater requiring treatment before disposal and generates product that may cause engine malfunction. This review work aimed at providing detailed and up-to-date record of the trend in renewable catalyst development in biodiesel synthesis. This is expected to inform a suitable selection and reaction conditions in the development of biodiesel from the very many feed stocks.

“…In contrast, transesterification studies reported by Boz and Kara [55] and Endalew et al [25], among others, show high BD yields working at 60°C with improved solid catalysts. The reaction time was set to reach the maximum possible conversion in 2 h as reported in other studies for heterogeneously catalysed systems [60]. Agitation rate reported range is quite wide, depending on the transesterification study for homogeneous or heterogeneous catalysts, the agitation may vary from 1200 rpm [61] to 100 rpm [62], respectively.…”

Vegetable oils are a vast triglyceride source for biodiesel production; i.e. fatty acid methyl esters (FAME), with methanol and a catalyst via transesterification reaction. The aim of this work was to study heterogeneously catalysed biodiesel production with solid oxides such as mayenite (Ca 12 Al 14 O 33 ) and alumina (Al 2 O 3 ) as catalyst carriers using edible rapeseed oil as feedstock. These oxides were impregnated to have Li 2 O and MgO concentrations of 5-10 and 5-30 wt% on each carrier, respectively. The catalysts were characterized using N 2 -physisorption (BET/BJH), scanning electron microscopy (SEM), and X-ray diffraction (XRD) analyses. The synthesized catalysts were mesoporous ranging from 119 to 401 Å and their chemical phase composition was confirmed by the XRD. The catalyst coating (MgO/Li 2 O) was studied, along with the catalyst amount in the reactor and the assessment of the transesterification reaction kinetics. The reaction was studied at 60°C, atmospheric pressure, agitation rate of 180 rpm, and a reaction time of 2 h in a 6:1 molar ratio of methanol to oil. For each catalyst, loadings of 2.5, 5, and 10 wt% relative to the oil weight were evaluated. The highest biodiesel yield was obtained by 5 wt% (relative to oil weight) impregnated mayenite catalyst coated with 10 wt% of Li 2 O. The kinetic data fits to a pseudo-first-order model having a reaction rate constant equal to 0.045 min -1 under these mild reaction conditions.
