Abstract
A process and system for converting a high-pour-point organic feedstock to an upgraded product that exhibits good low-temperature properties (cloud point, pour point, and viscosity) and improved transportability. The high-efficiency process includes a continuous-flow, high-rate hydrothermal reactor system and integrated separation systems that result in low complexity, small footprint, high energy efficiency, and high yields of high-quality upgraded product. The system is specifically desirable for use in converting waxy feedstocks, such as yellow and black wax petroleum crudes and wax from the Fischer-Tropsch (FT) process, into upgraded crude that exhibits a high diesel fraction and, correspondingly, low vacuum gas oil (VGO) fraction.
