In the last few years, important efforts have been made to synthesize so‐called “multipore” zeolites, which contain channels of different dimensions within the same crystalline structure. This is a very attractive subject, since the presence of pores of different sizes would favor the preferential diffusion of reactants and products through those different channel systems, allowing unique catalytic activities for specific chemical processes. In this Review we describe the most attractive achievements in the rational synthesis of multipore zeolites, containing small to extra‐large pores, and the improvements reported for relevant chemical processes when these multipore zeolites have been used as catalysts.

“…Methanol can be produced indirectly from the gasification of biomass through the process listed earlier and serves as a reactant to form many other high valued products such as acetic acid [46,47], acetic anhydride [47], BTX [48], chloromethanes [49], dimethyl oxalate [50], dimethyl carbonate [51], ethanol (and other higher alcohols [52]), ethylene [53] , ethylene glycol [54], formaldehyde [55,56], methyl acetate [57], methyl chloride [58], methyl formate [59][60][61], methyl esters [62,63], methyl glycolate [211,64], MTBE [65][66][67][68], methylamines [69][70][71], olefins, [72][73][74], propylene [75] and vinyl acetate [76]. Methanol can be the reactant to form many higher alcohols but one common practice is methanol coupling to form ethanol.…”

This article reviews subjects dealing with the chemistry, catalytic poisoning, newer catalyst technologies and possible future solutions to increase the efficiency of creating high-value products by thermochemically converting gasified biomass (producer gas). This article puts emphasis on bi-functional catalysts containing transition metals coupled with zeolites for renewable-fuel production. High-value products such as gasolinerange hydrocarbons, dimethyl ether, aldehydes, isobutane, isobutene and other olefins can be produced with gasified biomass due to the gas containing syngas (H 2 + CO). The chemistry and production of these chemicals are discussed in this article. The importance of certain process variables, such as temperature, space velocity, gas ratios, and pressure are discussed along with the importance of reactor design. The subject of the importance of the cleanliness of the producer gas, so that maximum high-value product yield can be achieved with the greatest efficiency, is also discussed.
