Lignin is a highly cross-linked macromolecule which consists of various oxygen and carbon bridges between alkylated methoxyl-phenol rings.And it offers great possibilities for the production of high value-added renewable products such as hydrocarbon compounds.However,efficiently depolymerizing lignin is the bottleneck for its widely application.As one of the main methods for production of hydrocarbon compounds from lignin,catalytic pyrolysis has attracted increasingly attention.In this review,recent researc...
