“…At present, the fixed-bed reactor MTP process has been developed by employing HZSM-5 zeolite as a catalyst [5,6]. HZSM-5 zeolite has 0.53 × 0.56 nm straight channels and 0.51 × 0.55 nm sinusoidal channels with appropriate acidity, and exhibits high reactivity and good shape-selectivity towards the MTP process [7].…”

Nanocrystal HZSM-5 zeolite aggregates with different SiO 2 /Al 2 O 3 molar ratios were prepared under low temperature and were used to catalyze the conversion of methanol to propylene and butene. The coke location, coke content, and coke species deposited on HZSM-5 aggregates were investigated. The near-graphite carbon on the external surface of HZSM-5 zeolite (SiO 2 /Al 2 O 3 molar ratio = 400) was distinguished by transmission electron microscopy (TEM) and energy dispersive spectrometer (EDS). The carbon distributions in the micropores and on the external surface of the spent HZSM-5 were revealed by thermogravimetric analysis (TGA) and Brunauer-Emmett-Teller (BET) results. Coke preferred to deposit in the mircopores of low SiO 2 /Al 2 O 3 molar ratio samples (200, 300) with relatively uniform Al distribution, while coke also preferred to deposit on the external surface and in the intergranular spaces of high SiO 2 /Al 2 O 3 molar ratio sample (400) with an obviously poor Al core and rich Al shell.

“…Methanol is a leading candidate to provide the hydrogen necessary to power a fuel cell, especially in vehicular applications (Ledjeff-Hey et al, 1998;Mokrani & Scurrell, 2009;Olah et al, 2009). Methanol is currently used as a feed stock for a variety of widely used organic chemicals, including formaldehyde, acetic acid, chloromethane, and methyl tert-butyl ether (MTBE).…”

“…Following, an overview of the process configurations selected for the techno-economic assessment of the synthesis section is provided taking the layouts from related references [8][9][10][11] as basis for the design. For each of the three considered concepts, the process from biomass-derived syngas to the respective final products is described.…”

“…A few commercial plants were operated using the MTG (methanol-to-gasoline) technology or combining the MTO (methanol-to-olefins) and MOGD (Mobil olefins-to-gasoline and distillate process) technologies for gasoline production. These plants were shut down after the recovery of crude oil prices [8]. Currently, such processing is regaining attention but using biomass instead of coal as feedstock.…”

The conversion of low-grade lignocellulosic biomass such as residual wood or straw to synthetic fuels and chemicals is currently being developed within the bioliq® concept (at the Karlsruhe Institute of Technology -KIT, Germany). The aim of this study is to model and assess three different synthesis process concepts with DME (dimethyl ether) as a platform chemical. The process concepts are designed and assessed using existing technologies, as well as the previous studies for pyrolysis and gasification sections. The respective considered products in the selected concepts are synthetic gasoline, ethylene and propylene.Using biomass for these applications can reduce fossil CO2 emissions by replacing non-renewable carbon sources. The techno-economic assessment concludes that total energy efficiency ranges between 37.5% and 41.1% for the production of gasoline and olefins, respectively. The resulting specific production cost in the gasoline concept is 72% higher than the current market price. In the olefins concept the difference to the current market prices of ethylene and propylene is reduced to 40%. The specific production costs in the gasoline and ethylene concept are 59% higher than current market prices. The possibility to sequestrate CO2 within the considered concepts at costs of 39 €/t allow additional revenues from sequestrated CO2. In order to meet current market prices, the implications of sequestrated CO2, mineral oil tax reduction and the combination of both kinds of subsidies are evaluated in this study. Keywords:Techno-economic assessment; Thermochemical biorefinery; Process design and simulation; Dimethyl ether (DME); Gasoline; Olefins IntroductionThe European Union enforces the use of biomass derived transportation fuels by setting a share of 10% biofuels for 2020 [1]. Synthetic gasoline produced from biomass is one of the most promising alternative fuels since it can be used in regular internal combustion engines without modifications. Furthermore biomass can reduce fossil CO 2 emissions by replacing nonrenewable carbon sources in other applications, such as in the chemical industry. The biobased production of olefins is a promising way to produce plastics from biomass. The integrated production of multiple products from biomass is currently discussed for future-expected thermochemical biorefineries using dimethyl ether (DME) as platform chemical, as for example using the DME (hydro)carbonylation route for the production of ethanol, methyl acetate DME and hydrogen from syngas (synthesis gas) [2]. In this study we assess the production of olefins and gasoline separately, i.e. two different concepts, and also the co-production (multiproduction) of gasoline and ethylene.
