Recent progress in the catalytic thermochemical conversion process of biomass for biofuels

Recent Research Advancements in Catalytic Pyrolysis of Plastic Waste

“…It is particularly fascinating that some resins, such as polyamides (PA), poly­(methyl methacrylate) (PMMA), and polystyrene (PS), thermally degrade to provide significant yields of their monomers. However, collected plastic from municipal waste is frequently a combination of different polymers, producing a blend of products that includes diverse hydrocarbons with variable chain lengths. , Catalytic pyrolysis is an attractive prospect for a secure circular economy since it can handle hazardous compounds as well as obsolete compounds and prevent their transfer into new products. , …”

“…22,23 Catalytic pyrolysis is an attractive prospect for a secure circular economy since it can handle hazardous compounds as well as obsolete compounds and prevent their transfer into new products. 24,25 Despite a large number of studies and encouraging outcomes for the catalytic pyrolysis of plastic, detailed analyses and reviews on plastic conversion using catalytic pyrolysis are not typically reported. Thus, this review comprehensively examines recent advancements in the catalytic pyrolysis processes that utilize plastic waste as a feedstock to generate biofuels, chemical compounds, and other valuable products, which eventually fulfill sustainability.…”

Research advancement in molten salt-mediated thermochemical upcycling of biomass waste

“…Biomass is commonly valorized into solid carbon, liquid fuel, or gaseous syngas via specific thermochemical conversions (i.e., thermal hydrolysis, pyrolysis, and gasification). 1,2 In particular, fast pyrolysis efficiently converts biomass into biochar and bio-oil, which can be further upgraded into value-added carbon materials, biofuels, and chemicals via in situ and ex situ catalysis strategies. 3,4 However, the commercialization of fast biomass pyrolysis is usually restricted by the bottleneck of heat transfer, 5 which is urgently needed to be solved in a sustainable manner.…”

In situ reduction of Cu nanoparticles on Mg-Al-LDH for simultaneous efficient catalytic transfer hydrogenation of furfural to furfuryl alcohol

“…Selective transformation of sustainable biomass or biomassbased feedstocks into value-added chemicals is highly desirable. [1][2][3] Among many biomass-based catalytic reactions, the efficient hydrogenation of furfural (FAL) to furfuryl alcohol (FOL) is an important process in industrial production. [4][5][6] However, FAL has a variety of unsaturated functional groups, so one challenge for the efficient transformation of FAL to FOL is the selective hydrogenation of CQO bonds rather than CQC bonds, while avoiding excessive hydrogenation or ring-opening reactions.…”
