A heat integrated steam reformer, which incorporates a catalytic combustor, which can be used in a fuel processor for hydrogen production from a fuel source, is described. The reformer assembly comprises a reforming section and a combustion section, separated by a wall. Catalyst (21) able to induce the reforming reactions is placed in the reforming section, either in the form of pellets or in the form of coating on a suitable structured catalyst substrate such as fecralloy sheets. Catalyst (22) able to induce the combustion reactions is placed in the combustion section in the form of coating on suitable structured catalyst substrate such as fecralloy sheet. A steam and fuel mixture (30) is supplied to the reforming section (14) where it is reformed to produce hydrogen. A fuel and an oxygen (32) containing gas mixture is supplied to the combustion section where it is catalytically combusted to supply the heat for the reformer. The close placement of the combustion and reforming catalysts facilitate efficient heat transfer. Multiple such assemblies can be bundled to form reactors of any size. The reactor made of this closely packed combustion and reforming sections is very compact.

Herein are described apparatus and processes for the preparation of cannabinoids, such as cannabidiol (CBD) and derivatives thereof. The apparatus and processes described can be used for the one-step, flow-mediated synthesis of cannabidiol and derivatives with improved overall yield, material throughput, and product purity relative to batch processes.

An analytical method for precipitated particles using a co-precipitation reaction in includes feeding streams and a tracking metal into a reaction vessel; collecting a precipitated product containing the tracking metal from the reaction vessel in increments of time to obtain product samples; filtering each collected product sample to separate precipitated particles from filtrate; and performing elemental analysis for the tracking metal in the precipitated particles of each collected product sample and measuring a concentration of the tracking metal in the precipitated particles, to obtain a residence time distribution of the precipitated particles in the reaction vessel according to the concentration of the tracking metal in the precipitated particles. Therefore the preferred residence time of the precipitated particles in the reaction vessel can be ascertained, so that it is clear when the precipitated particles should be collected from the reaction vessel.

One or more embodiments presently disclosed is directed to a method for reacting a chemical stream which may include contacting the chemical stream with a catalyst to produce a product stream. The catalyst may include alumina, silica, and a catalytically active compound such as tungsten.

A multi-stage process for the production of an ISO 8217 compliant Product Heavy Marine Fuel Oil from ISO 8217 compliant Feedstock Heavy Marine Fuel Oil involving a Reaction System composed of one or more reactor vessels selected from a group reactor wherein said one or more reactor vessels contains one or more reaction sections configured to promote the transformation of the Feedstock Heavy Marine Fuel Oil to the Product Heavy Marine Fuel Oil. The Product Heavy Marine Fuel Oil has a sulfur level has a maximum sulfur content (ISO 14596 or ISO 8754) between the range of 0.05 mass % to 1.0 mass. A process plant for conducting the process for conducting the process is disclosed that can utilize a modular reactor vessel contained within a frame work based on ISO 40 foot or ISO 20 foot container dimensions.

The invention relates to Fischer-Tropsch synthesis in a compact version. A compact reactor comprises a housing, rectangular reaction channels inside the housing, which are filled with a cobalt catalyst, synthesis gas injection nozzles in the number determined by the ratio of the number of channels to the number of synthesis gas injection nozzles, an input and output nozzle for heat transfer medium on which a pressure controller installed, and an assembly for withdrawing synthetic hydrocarbons. The cobalt catalyst is activated by passing hydrogen through it. Synthetic hydrocarbons are produced by passing synthesis gas through the reaction channels filled with the activated cobalt catalyst. The space velocity of synthesis gas is increased every 300-500 h, followed by returning to the initial process conditions. This provides a high-molecular-weight hydrocarbon output per unit mass of the reactor.
