Abstract. Methods for fuel oils processing that are implemented at oil refineries are complex and high-cost, therefore development of effective technologies is a relevant task. 5M3TECH LLC proposes an effective technology for fuel oil processing using low-thermal catalytic cracking with methane as hydrogen donor.
Fuel oil processing occurs as follows. Fuel oil is being mixed with methane at mixing unit and heated to 360°C at furnace, then the mixture enters catalytic reactor, where low-thermal catalytic cracking occurs on the catalyst of our own development and manufacturing (patent application submitted). Reaction mixture then is being moved to separation, where hydrocarbon gas, gasoline, diesel fuel and high-boiling residue, that could be sent for recycling, are being separated. The proposed innovative technology developed by 5M3TECH LLC allows to process up to 95% of fuel oil.
The technology of low-temperature catalytic cracking of fuel oil with methane as a hydrogen donor is relevant for refineries that do not have fuel oil processing processes, since it replaces a vacuum distillation unit, a catalytic cracking unit, and a coking unit. It is available for most refineries due to the fact that the expected cost of plant construction is approximately 80% cheaper than classical hydrocracking and coking technologies.
