Chemical reactor for the conversion of methane to aromatic hydrocarbons

Catalysis, Molecular Separations and Reactor Engineering Group (CREG) has developed through a project supported by the National R + D an innovative type of chemical reactor. In this project, in which CEPSA acted as an Observer Company (EPO), promising results were obtained with a fluidized bed reactor of two zones with variable section, for transforming methane into aromatic hydrocarbons. In particular, the reactor allowed to counteract the effect of catalyst deactivation, when performing the regeneration reaction itself in one of the zones, while carrying out the desired aromatization reaction on the other. This prevents the conversion decreased with time having conventional reactors. Having two separate sections for each of the two zones, the flows can be adapted to the needs of the reaction that takes place in each zone.

This technology is of great interest to CEPSA, as aromatic hydrocarbons represent the basis of most of the processes developed by the chemical branch of CEPSA. Given the rising price of oil, the differential between natural gas and aromatic hydrocarbons (usually derived from oil) makes it especially interesting to have an alternative technology. This has led to collaboration between CREG and CEPSA group through a CDTI (Centre for Industrial Technological Development to the Spanish Ministry of Economy and Competitiveness) project, currently in progress, aimed at testing the scaling (step pilot plant) of this technology.

Note that the conversion of natural gas into liquid fuels (GTL) is one of the great challenges for catalysis. Aromatization of methane is a process discovered in the 90s. Compared to other already established processes GTL technology presents several advantages: it allows to obtain aromatic hydrocarbons and needs no intermediate step of obtaining the synthesis gas which has a low energy efficiency. Despite the above industrial application has been hampered by the problem of catalyst deactivation. The reactor developed by the CREG presents a solution to this problem and therefore allow the use of natural resources (dispersed natural gas, biogas) currently unused and CEPSA provide an alternative source for obtaining oil from the starting materials in which production is based chemical (detergents, polymers, solvents, etc.).

M. Menéndez, J. Herguido, C. Tellez, J. Soler, M.P. Gimeno, Two zone fluidized bed reactor. Patent number: WO2009153382. This patent describes a new kind of reactor, in particular of two zone fluidized bed reactor with a variable section. The two zone fluidized bed reactors allows carrying a reaction in one zone of the bed and the catalyts regeneration in another zone of the bed. This characteristic makes this reactor suitable for reactions where the catalyt is deactivated along time by coke deposition. Other applications disclosed in the patent include the use for reactions in which a catalyst can act as oxygen carrier, transporting oxygen in the solid lattice between both zones, and the use as a filter to remove tar and solid particles from a gaseous stream, using the oxidation zone to remove such tar and particles from the solid being fluidized.

This patent describes a procedure to obtain aromatic hydrocarbons, such as benzene but also toluene and naphthalene from a stream containing methane, using a catalyst suitable for the application in a fluidized bed reactor and a fluidized bed reactor. In particular, the use of a two zone fluidized bed reactor for this application is described, showing the capability to operate in steady state, thanks to the continuous catalyst regeneration achieved in this system.
