The present disclosure provides systems and methods for processing ammonia. The system may comprise one or more reactor modules configured to generate hydrogen from a source material comprising ammonia. The hydrogen generated by the one or more reactor modules may be used to provide additional heating of the reactor modules (e.g., via combustion of the hydrogen), or may be provided to one or more fuel cells for the generation of electrical energy.

Hydrogen generation assemblies, hydrogen purification devices, and their components, and methods of manufacturing those assemblies, devices, and components are disclosed. In some embodiments, the devices may include an insulation base having insulating material and at least one passage that extends through the insulating material. In some embodiments, the at least one passage may be in fluid communication with a combustion region.

A process and a system thereof include apparatuses for developing multi-component vapor mixture by heating of solution of reactants comprising one or more of diphenols, or diphenol derivatives, and an organic compound. Upon reacting in a vapor state in presence of a catalyst with diphenols, or diphenol derivatives, the organic compound produces a monoalkyl ether of a dihydric phenolic compound. The entire solution of reactants completely transforms into a super-heated multi-component vapor using heaters without the use of thin film evaporator. The complete transformation of the entire solution of the reactants in to super-heated multicomponent vapor is achieved by heating the entire solution firstly by a pre-heater followed by further heating by a super-heater. The unevaporated or condensed high boilers and tar are removed to drain. The superheated vapor is subjected to vapor phase reaction mediated by catalyst to get monoalkyl ether of a dihydric phenolic compound.

A chemical reactor that combines a pressure vessel, heat exchanger, heater, and catalyst holder into a single device is disclosed. The chemical reactor described herein reduces the cost of the reactor and reduces its parasitic heat losses. The disclosed chemical reactor is suitable for use in ammonia (NH.sub.3) synthesis.

The present application provides a system and method for producing a silicon-containing product by using a silicon sludge, which is produced by a cutting silicon material with a diamond wire. The method utilizes a high oxide layer on the surface of a silicon waste particle produced during diamond wire cutting. The surface oxide undergoes a disproportionation reaction with adjacent internal elemental silicon to form silicon monoxide, which is removed in a vapor to achieve a physical chemical reaction with a metal, a halogen gas, a hydrogen halide gas or hydrogen to form silicon-containing products of higher added value. The process realizes the large-scale, high-efficiency, energy-saving, continuous and low-cost complete recycling of silicon waste produced by diamond wire cutting of silicon material.

A reactor and a process for fluid catalytic cracking (FCC) a hydrocarbon feed in the riser-reactor, the process including injecting the hydrocarbon feed into an evaporation zone of the riser-reactor, injecting a first catalyst into the evaporation zone, wherein the first catalyst mixes with the hydrocarbon feed to generate a hydrocarbons stream in the evaporation zone, and wherein the temperature in the evaporation zone is less than 625° C., and passing the hydrocarbons stream from the evaporation zone into a cracking zone of the riser-reactor to generate a cracked product in the cracking zone.

A reverse flow reactor (RFR) and process having a forward reaction feed cycle, a reverse reaction feed cycle, and a reverse regeneration cycle. The heat convected in the forward feed cycle matches the heat convected in the reverse flow cycles. Compared to an RFR without the reverse feed cycle, the three-cycle RPR substantially reduces the regeneration air flow rate, associated compression requirements, and the overall reactor volume, that are required.
