Abstract

The invention discloses a pyrolysis device and a primary pyrolysis product detection assembly and detection method. The pyrolysis device comprises an inner liner tube and a heating wire. The heating wire is wound on the outer wall of the inner liner tube. The inner liner tube is provided with an elongated tube body and a channel extending along the length direction of the elongated tube body is arranged inside the elongated tube body. One end of the channel is provided with a sample inlet and a carrier gas inlet, and the other end of the channel is provided with a discharge port. The elongatedtube body is also provided with a sampling hole communicating the channel with the outside fluid. The device, the assembly and the method are easy to operate, samples do not need pretreatment, products do not need collection and extraction and rapid and in-situ analysis and detection of pyrolysis products can be realized.

Description

technical field [0001] The invention relates to experimental techniques in the field of thermal analysis, in particular to a pyrolysis device, a primary pyrolysis product detection component and a detection method. Background technique [0002] my country is a country rich in coal (charcoal), less (natural) gas, and poor in (petroleum) oil. It is also a large agricultural country and can produce a huge amount of biomass every year. Therefore, the development of clean and comprehensive utilization methods of coal and biomass is an inevitable requirement for my country's future energy development and planning. In addition, the increasing amount of waste polymers is also an important available resource. Complex mixtures such as biomass, coal, and waste polymers can be converted into high-quality liquid fuels through processes such as pyrolysis and catalysis, reducing dependence on petroleum resources. [0003] During the pyrolysis process of complex mixtures, the reactants wi...
