英语翻译
Catalytic pyrolysis of biomass over H-ZSM5 has been
extensively shown to convert the biomass derived oxygenates
into aromatic hydrocarbons and is a method available to
produce deoxygenated pyrolysis liquids.H-ZSM5,a shape-
selective acid catalyst,acts to initiate conversion of the
oxygenates through carbocation formation,30leading to olefins
that aromatize in the presence of the catalyst.Because of the
chemical diversity of the functional groups found in the
biomass-derived vapors encountering the H-ZSM5 catalyst,
many different mechanisms are initiated including decarbox-
ylation,decarbonylation,dehydration,and dehydrogenation.31
The latter two lead to loss of hydrogen from the biomass,and
because biomass is already hydrogen deficient,the pathway
leads to coke formation.This coke formation represents a loss
of carbon that needs to be converted to liquids; therefore,
catalytic pyrolysis,despite its potential for producing
In the presence of H-ZSM5,pyrolysis of plastics has shown to
be active in converting aliphatic hydrocarbons to aromatics
through a similar mechanism of olefin formation followed byless of a problem in the latter case because unlike biomass there
is more hydrogen available to support the formation of liquid
range products.
