Pyrolysis technology has received increasing attention in recent years due to its great
potential in the field of low-rank coal clean and efficient conversion. Since pyrolysis reaction …

The volatiles' reaction has a significant influence on the yield and quality of tar during
pyrolysis of low-rank coals. To clarify the effect of volatiles' reaction on the coking behavior of …

In this paper, utilization of Victorian brown coal in a drying–pyrolysis process to make
products is techno-economically assessed. The pyrolysis process is coupled with the drying …

Heat transfer between binary particles in an internally heated downer pyrolyzer was
carefully studied because it is an important element for the reactor design, but a consensus …

A novel self-mixing down tube (SDT) pyrolyzer has been developed, which can separate the
heat carrying particles preheated in the fluidized bed from the coal, and the two can be …

Downer reactors are the reactors of choice for fast chemical reactions, such as those
associated with cracking of heavier feedstock in petroleum refineries. The objective of this …

在碳中和目标下, 未来发展之路是从化石能源的原料体系转变到可再生能源的原料体系.
作为化石资源的重要替代品, 生物质是唯一能够大规模取代化石资源的可再生碳资源 …

ReaxFF molecular dynamic simulation combined with experimental verification was
performed to understand the overall reaction mechanism, especially the primary and …

Pulverized coal pyrolysis based on solid heat carrier has a huge advantage in high tar yield.
In this study, pyrolysis experiments on pulverized coal were conducted in a lab-scale …

A drag model based on the “spatial superposition” assumption is built to better simulate the
local heterogeneous structure of the downer in a triple-bed circulating fluidized bed system …
