One-step production of long-chain hydrocarbons from waste-biomass-derived chemicals using bi-functional heterogeneous catalysts

Abstract

In this study, we demonstrate the production of long-chain hydrocarbons (C 8+ ) from 2-methylfuran (2MF) and butanal in a single step reactive process by utilizing a bi-functional catalyst with both acid and metallic sites. Our approach utilizes a solid acid for the hydroalkylation function and as a support as well as a transition metal as hydrodeoxygenation catalyst. A series of solid acids was screened, among which MCM-41 demonstrated the best combination of activity and stability. Platinum nanoparticles were then incorporated into the MCM-41. The Pt/MCM-41 catalyst showed 96% yield for C 8+ hydrocarbons and the catalytic performance was stable over four reaction cycles of 20 hour each. The reaction pathways for the production of long-chain hydrocarbons is probed with a combination of infrared spectroscopy and steady-state reaction experiments. It is proposed that 2MF and butanal go through hydroalkylation first on the acid site followed by hydrodeoxygenation to produce the hydrocarbon fuels.

Upgrading HMF derived GVL into liquid hydrocarbons is also possible through two different pathways.…”

Selective One‐Pot Production of High‐Grade Diesel‐Range Alkanes from Furfural and 2‐Methylfuran over Pd/NbOPO4

“…Because the HAA condensation of HMF and/orf urfural with 2-MF is catalyzed by acid, [6c-f, 10] integration with the following metal/acid-catalyzed HDO reaction is much easier.F or example, Lauterbach and coworkers reported ao ne-step production of C 8 + hydrocarbons from 2-MF and butanal over ab ifunctionalP t/MCM-41 catalyst. [11] However,t he obtained hydrocarbons were mainly linear n-nonaneand n-octane, which are considered to be less attractive owing to their low octane number.…”

Kinetic study of the competitive hydrogenation of glycolaldehyde and glucose on Ru/C with or without AMT

“…Lignocellulose is being considered as a sustainable alternative to fossil feedstock for the production of fuels and chemicals. Various chem‐ and bio‐transformation routes have been developed to this end, among which the one‐pot chemical transformation of cellulose to ethylene glycol (EG) and propylene glycol may provide a new route for the production of commodity chemicals from renewable biomass . Although a great deal of efforts have been devoted to the design and development of effective and robust catalysts, the reaction kinetics as well as the underlying mechanism implications have rarely been studied, possibly due to the complicated nature of the involved reactions.…”
