The fast heating in MHyPy process results in the same conversion rate as that of the slow heating in HyPy process, which leads to the less reaction time and high yield of oil.
采用快速升温多段停留的工艺可以达到慢速升温时的转化率，可节省反应时间并增加油的收率；

High conversion could be obtained by using the tail oil circulation process and other integrated processes.
采用尾油循环和其它组合工艺，可以得到较高的重渣油加氢转化率。

"Coal topping process" is a new technology which produce heat, power, gas and oil together. It combine CFB technology with coal conversion technology.
