本文介绍了美国德士古以全新概念开发的新工艺──采用沸腾床式反应器加氢炼制、裂解减压瓦斯油。用该反应器能最大限度地利用催化剂颗粒的性能，该工艺既优越于传统的固定床工艺，经济效益又好。
This article describes a new process developed by Texaco in the United States that uses a bubbling bed reactor to hydrogenate and crack vacuum gas oil. The use of the reactor to maximize the performance of the catalyst particles, the process is superior to the traditional fixed-bed process, and good economic returns.
