Summary of laboratory simulation studies of the ROPE(trademark) process

摘要

The Western Research Institute is currently developing a process for the recovery of distillable liquid products from alternate fossil fuel sources such as tar sand and oil shale. The fundamental processing concept is based on recycling a fraction of the produced oil back into the reactor to be mixed with the raw resource. This concept is termed the recycle oil pyrolysis and extraction (ROPE(trademark)) process. The conversion of the alternate resource to a liquid fuel is performed in two stages. The first pyrolysis stage is performed at moderate temperatures (325--420(degree)C (617--788(degree)F)) in the presence of product oil recycle. The second stage is performed at higher temperatures (450--540(degree)C (842--1004(degree)F)) in the absence of product oil.
