石油焦的比气化反应速率与孔隙结构有着紧密的关系，比气化反应速率和有效比表面积之间有着较好的线性关系。

The reactivity has a close relationship with pore structure. There is a good linear relation between the specific gasification rate and the effective specific surface area.

这些极小的小孔使分布稀薄的催化剂保持在原位上，并且能留出有效分解这种燃料所需的尽量大的表面积。

The minuscule pores keep the thinly spread catalyst in place and create the large surface area needed to break down the fuel effectively.
