A reactor arrangement for performing, by means of at least one solid reaction member(s), a biological or chemical transformation, or physical or chemical trapping from, or release of agents to, a fluidic media in a continuous process. The arrangement comprises at least one reactor with a cylindrical reaction vessel (11) in which at least one reactor a transformation device (100) has been mounted. The vessel (11) comprises at least one inlet port (30) in the vicinity of its bottom wall (18) and at least one outlet port (40) arranged in the vicinity of its upper end portion. Each inlet port (30) is connected to a fluid supply member (300) configured to be submerged below the fluid surface level in a pool or a pond. The fluid supply member (300) comprises at least one inlet opening (301) configured to continuously supply a fluid from the pool or the pond to the vessel (11). Each outlet port (40) is configured to continuously let out the fluid from the vessel (11) to the pool or the pond via the outlet port (40). Further a method of using the reactor arrangement is provided.

A method for ammonia (NH.sub.3) decomposition to hydrogen (H.sub.2) and nitrogen (N.sub.2) includes introducing and passing a H.sub.2-containing feed gas stream into a reactor containing an industrial waste-based nickel (Ni-SMR) catalyst at a temperature of 500 to 900 C. to form a reduced Ni-SMR catalyst; introducing and passing an NH.sub.3-containing feed gas stream through the reactor in contact with the reduced Ni-SMR catalyst at a temperature of 100 to 1000 C. thereby converting at least a portion of the NH.sub.3 to H.sub.2 and regenerating the Ni-SMR catalyst particles to form a regenerated Ni-SMR catalyst, and producing a residue gas stream leaving the reactor; and separating the H.sub.2 from the residue gas stream to generate a H.sub.2-containing product gas stream.

An internal circulation catalytic reactor includes a body extending along a longitudinal axis Z and defining an internal chamber, a catalyst bed located within the internal chamber, the catalyst bed being configured to hold a catalyst, an inlet fluidly connected to the catalyst bed and configured to receive a feed, an outlet fluidly connected to the catalyst bed and configured to discharge a product generated by an interaction of the feed and the catalyst, and an impeller fluidly connected to the catalyst bed and configured to circulate the feed through the catalyst bed. The impeller is configured to discharge a recirculate feed at a non-zero angle relative to a horizontal radial axis R.

System for mixing a catalyst precursor into heavy oil using a high boiling hydrocarbon diluent to form a diluted precursor mixture, which is mixed with the heavy oil to form a conditioned feedstock, which is heated to decompose the precursor and form dispersed metal sulfide catalyst particles in situ. The high boiling hydrocarbon diluent is at a temperature above the decomposition temperature of the catalyst precursor and is first fed through a cooler and/or mixed with a cooler diluent to reduce its temperature and avoid premature decomposition of the catalyst precursor. The high boiling hydrocarbon diluent may include a portion of the heavy oil feedstock, a portion of the conditioned feedstock, a vacuum tower bottoms product, or other high boiling hydrocarbon material having a boiling point higher than 524 C. A portion of the diluent may optionally include a medium boiling hydrocarbon material having a boiling point less than 524 C.

System and method for mixing a catalyst precursor into heavy oil using a high boiling hydrocarbon diluent to form a diluted precursor mixture, which is mixed with the heavy oil feedstock to form a conditioned feedstock, which is subsequently heated to decompose the precursor and form dispersed metal sulfide catalyst particles in situ. Because the high boiling hydrocarbon diluent is typically at a temperature above the decomposition temperature of the catalyst precursor, it is first feed through a cooler to reduce its temperature to avoid premature decomposition of the catalyst precursor. The high boiling hydrocarbon diluent may include a portion of the heavy oil feedstock, a portion of the conditioned feedstock, a vacuum tower bottoms product, or other high boiling hydrocarbon material having a boiling point higher than 524 C. A portion of the diluent may optionally include a medium boiling hydrocarbon material having a boiling point less than 524 C.
