“…On the other hand, the addition of chemical additives to improve the performance of WO 3 in this photocatalytic reaction has also been reported. Taylor and Noceti showed that the addition of H 2 O 2 improved the generation of methanol, as this species can be a source of hydroxyl radicals, which are an important intermediate that contributes to the CH 3 OH formation [6]. In contrast, Gondal et al evidenced that hydrogen peroxide has no influence in enhancing the production yield of methanol but the addition of Fe 3+ can help to maintain the production of methanol over the reaction (batch type) [7].…”

“…The conversion of CH 4 (X CH4 ) and fraction of total input carbon converted into CH 3 OH (F CH3OH ), HCHO (F HCHO ) and C 2 H 2 + C 2 H 4 + C 2 H 6 (F C2 ) were calculated as, Unlike in other studies (Matsumoto, et al 2001), X CH4 was less than 12% at a 2% CH 4 feeding concentration, and a 50 cm 3 /min -1 total flow rate, while X CH4 was about 4% with a 5.0 mL/min -1 CH 4 flow rate (Taylor et al 2000). X CH4 with typical solid catalysts reported by Otsuka (2001) was 0.7% to 18.5%.…”

The direct conversion of methane (CH 4 ) into methanol (CH 3 OH) and HCHO in an Argon (Ar) 50W radio-frequency plasma system was applied and the effects of various feed compositions, CH 4 /O 2 ratio, and plasma discharge areas were compared. Additionally, the effects of various methane to oxygen ratios and plasma discharge areas were studied. It was found that in an Ar stream, the CH 3 OH conversion ratio in the CH 4 /O 2 plasma system was higher than that in CH 4 /CO, CO/H 2 and CH 4 /H 2 /O 2 plasma systems.The conversion of CH 4 reached 19.1% at CH 4 /O 2 = 40/60; the yield of CH 3 OH was 1.12% and 16.0% CO, the major product, was produced. A larger plasma discharge area, resulting in a longer residence time, corresponded to higher CH 4 conversion, but a lower CH 3 OH conversion ratio, because of further decomposition into CO and CO 2 . Interestingly, no carbon deposition was observed in the RF plasma system, and the carbon balance was between 0.94 and 1.19.

“…Bio methanol can be produced via several processes including pyrolysis, bio synthesis, gasification, and electrolysis, using a wide range of biomass waste, such as agricultural, forest, and municipal [17,[53][54][55]. Although most of these processes are currently under development, the installation of bio methanol production units requires further studies on design and energy efficiency in order to ensure feasibility of large scale application [56].…”

Olefins from Biomass Intermediates: A Review

2017

View full text Add to dashboard Cite

Over the last decade, increasing demand for olefins and their valuable products has prompted research on novel processes and technologies for their selective production. As olefins are predominately dependent on fossil resources, their production is limited by the finite reserves and the associated economic and environmental concerns. The need for alternative routes for olefin production is imperative in order to meet the exceedingly high demand, worldwide. Biomass is considered a promising alternative feedstock that can be converted into the valuable olefins, among other chemicals and fuels. Through processes such as fermentation, gasification, cracking and deoxygenation, biomass derivatives can be effectively converted into C 2 -C 4 olefins. This short review focuses on the conversion of biomass-derived oxygenates into the most valuable olefins, e.g., ethylene, propylene, and butadiene.
