“…However, the high coking tendency and associated catalyst deactivation are clear disadvantages of zeolites [22,23]. Modifying zeolites with various promoters such as lanthanum [7], gallium [24], and phosphorous [25] can change the acidity and the selectivity toward the desired product. The addition of a second metal promoter with an optimum amount may provide a more diverse control of the surface acidity.…”

“…The addition of a second metal promoter with an optimum amount may provide a more diverse control of the surface acidity. Another advantage of these promoted catalysts is their lower coking tendency compared to base catalysts with rapid inactivation while the promoted catalysts maintain their activity for a longer period of time [8,25].…”

“…A wide range of fuels and raw chemicals conventionally produced from petroleum can be obtained from these raw materials. Bio‐ethanol is well‐known for its potential as an alternative fuel, and also noteworthy is the technological development of bio‐ethanol conversion into hydrocarbons, chemical platforms, and H 2 (via steam reforming) . However, bio‐ethanol valorization is limited by the availability of fermentable biomass, given that sugars production from lignocellulosic biomass (which would not interfere with the human and animal feed chain) is still under development …”

Recent advances in lignocellulosic biomass valorization for producing fuels and commodities (olefins and BTX aromatics) are gathered in this paper, with a focus on the conversion of bio-oil (produced by fast pyrolysis of biomass). The main valorization routes are: (i) conditioning of bio-oil (by esterification, aldol condensation, ketonization, in situ cracking, and mild hydrodeoxygenation) for its use as a fuel or stable raw material for further catalytic processing; (ii) production of fuels by deep hydrodeoxygenation; (iii) ex situ catalytic cracking (in line) of the volatiles produced in biomass pyrolysis, aimed at the selective production of olefins and aromatics; (iv) cracking of raw bio-oil in units designed with specific objectives concerning selectivity; and (v) processing in fluidized bed catalytic cracking (FCC) units. This review deals with the technological evolution of these routes, in terms of catalysts, reaction conditions, reactors, and product yields. A study has been carried out on the current state-of-knowledge of the technological capacity, advantages and disadvantages of the different routes, as well as on the prospects for the implementation of each route within the scope of the Sustainable Refinery. /jctb 2 -C 4 olefins 147 a % Relative area: Percentage of total peak area detected by GC/MS semi-quantitative analysis.

“…The research work on the conversion of ETP over zeolite and transition metal oxide catalysts were reviewed by Li. The existing researches show that ZSM-5 is the best candidate for propylene production (Li et al, 2016). Levyne (LEV), which belongs to CHA type zeolite, exhibit the specific shape selectivity for the transformation of methanol or ethanol (Venkatathri and Yoo, 2008;Inoue et al, 2009;Bhawe et al, 2012).…”

The transformation of ethanol to propylene (ETP) was investigated over H-ZSM-5 (40) and H-LEV (40) catalysts. For H-ZSM-5 (40), the propylene yield kept constant at about 20.0% during 8 h. For H-LEV (40), higher initial propylene yield reached 34.0%. However, there is almost no propylene obtained over H-LEV (40) catalyst after 2 h. H-ZSM-5 (40) catalyst exhibited higher stability than H-LEV (40). The lower stability of H-LEV (40) is probably due to coke deposition. The reactant and products adsorption performances in the ethanol conversion reaction over H-ZSM-5 (40) and H-LEV (40) catalysts were studied by Monte Carlo simulations. Results show that the higher adsorption amount of ethanol, ethylene and propylene in H-LEV (40) led to the more difficult desorption of products and higher content of coke deposition.
