Glycerol reforming

Current biodiesel can not be considered as a 100% biomass-based fuel as long as methanol is derived from petrochemical resources. A clean way to solve the biorelated problem is the conversion of glycerol waste from the transesterification process into syngas. In this context, glycerol reforming is a suitable target reaction worthy of study.

Two-bed membrane reactor for integrated process involving aqueous-phase glycerol reforming to synthesis gas coupled with DME synthesis process combines two physically separated enclosures (Figure 5.13). The first unit is a tube-in-tube fixed-bed water perm-selective membrane reactor for DME synthesis process. The reaction-side compartment (outer tube) is packed with bifunctional catalytic particles for DME synthesis, whereas the permeate-side compartment (inner tube) is an empty...

With in situ H2O removal, the exothermic reactions in DME synthesis unit make possible the endothermic aqueous-phase glycerol reforming process, and the aqueous-phase glycerol reforming process produces the synthesis gas appropriate for DME synthesis process (Figure 5.15). Simulations surest that allothermal operation could be achieved the overall energy balance is favorable, and the synthesis gas produced in...
