Using petroleum/biomass refinery concepts to develop technologies for in-situ upgrading of heavy petroleum
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.
