摘要

Abstract

New opportunities to use

ex-situ

upgrading technologies currently in commercial application or in development for petroleum refineries and biomass conversion wer

e identified to be applied for

in situ

upgrading of heavy crude oils. The following technologies were recognized:

in situ

catalytic gasification to produce hydrogen uses similar concept than catalytic gasification of biomass

catalytic aquathermolysis with hydrogen donors mimics the visbreaking of petroleum residue with hydrogen donors

and the use of supercritical water with or without catalyst for

in situ

applications is based on hydrogenation reactions with supercritical fluids. The viscosity reduction of heavy oils through catalytic aquathermolysis varies depending on the catalysts used and reaction conditions

which has been reported to be of up to 74%

and adding hydrogen donor can further increase to 85%. Various advantages and disadvantages were identified and discussed for

in situ

technologies

particularly the inhibition of coke formation

the degree of heavy crude oil upgrading

the requirement of surface facilities

the design of catalysts

and the investment and operating costs.
