Study on microwave-assisted co-pyrolysis and bio-oil of Chlorella vulgaris with high-density polyethylene under activated carbon

Interaction Effects between the Main Components of Protein-Rich Biomass during Microwave-Assisted Pyrolysis

“…This could be ascribed to two main reasons. First, the unsaturated bonds in olefins and aromatic hydrocarbons were prone to react with O-containing and N-containing radicals, leading to the enhanced formation of O-containing compounds (in PL and CL) and N-containing compounds (in PC). ,, Second, the promotion of amines and nitriles denitrogenation resulted in the generation of alkanes in PC, and the promotion of decarboxylation of long-chain fatty acids led to the production of alkanes (such as pentadecane) in PL and CL. ,, In addition, the interactions in PL inhibited the generation of cycloalkenes, while the interactions in PC and CL enhanced the formation of cycloalkenes, which could be attributed to the interactions between them inhibiting or promoting the cyclization of olefins. , …”

“…Furthermore, the MAP of L could generate a significant quantity of H radicals due to the higher content of H element in L (11.00 wt %), promoting the bio-oil’s denitrogenation (Table ). ,, Consequently, this process inhibited the generation of N-containing compounds in the PL bio-oil while increasing the levels of O-containing compounds and hydrocarbons. In addition, the cracking of L was promoted during the copyrolysis of C and L, resulting in the generation of a substantial amount of long-chain fatty acids.…”

Microwave-Absorbing Catalysts in Catalytic Reactions of Biofuel Production

“…It was reported that total amount of 7.7 wt% water content in the bio-oil was decreased with the increment of bio-oil yield and decrement of biooil viscosity [36]. High hydrocarbons content was found using co-pyrolysis with the highest yield of hydrocarbon ranged from C7 to C12, following by C16 and >C18, and least amount of ketones in the obtained bio-oil [37]. High composition of hydrocarbons in bio-oil represents the better quality of bio-oil to be processed into biodiesel, renewable diesel, or aviation fuels.…”

Enhanced upgrading of corncob to furfuryl alcohol with a novel silica-supported SO42−-TiO2 chemocatalyst and immobilized whole-cell biocatalyst

“…22 In contrast, microwave technology is a highly effective technology for heating that uses less energy, produces uniform heating, and responds quickly. 23,24 Microwave heating is an important pretreatment that can effectively destroy the dense structure of lignocellulosic biomass. 25,26 There is an urgent need to investigate an efficient method for increasing the productivity of FFA production from agricultural waste biomass.…”
