Production of Monoethylene Glycol from Lignocellulosic Biomass via Catalytic Hydrogenation: A Review

Abstract Ethane and ethanol are produced through steam cracking fermentation into ethylene respectively, which is then hydrolysed monoethylene glycol (MEG). The disadvantages of both processes included used easily oxidized substance large quantities water in order to minimize by-products such as diethylene triethylene glycol. Apart from that, MEG can also be by catalytic hydrogenation biomass at extreme temperature pressure with presence catalyst. At the same time, this process uses lignocellulosic waste that have a high cellulose content residues agricultural food industries. However, has treated remove lignin may lower rate activity. In addition, most studies found range 240 °C 280 5 MPa 6 able produce 18 wt% 64 MEG. Meanwhile, catalyst attract researchers’ attention nickel tungsten species increase yield overcoming activation energy process. Factors lignocellulose’s pre-treatment, operating pressure, will discussed further.
