Loading system for loading a reactor with bulk material, which system can be disassembled and dismantled
A dismountable and dismantlable loading system for loading a reactor with bulk material, is described. The dismantlable rail system with a multiplicity of rail segments can be connected to one another to form a self-contained rail system, wherein the individual rail segments have the ability to connect the rail segments to one another. Also provided is at least one rail vehicle for operation on the rail system, having a holding device for containers for receiving the bulk material, and at least one filling station for receiving the bulk material, having a hose present in the floor of the filling station for transporting the bulk material into various areas of the reactor.
CONVERSION OF HYDROGEN SULFIDE AND CARBON DIOXIDE INTO HYDROCARBONS USING NON-THERMAL PLASMA AND A CATALYST
A feed stream is flowed to a catalytic reactor. The catalytic reactor includes a non-thermal plasma and a catalyst. The feed stream includes hydrogen sulfide and carbon dioxide. The feed stream is contacted with the catalyst in the presence of the non-thermal plasma at a reaction temperature, thereby converting the hydrogen sulfide and the carbon dioxide in the feed stream to produce a product. The product includes a hydrocarbon and sulfur. The product is separated into a product stream and a sulfur stream. The product stream includes the hydrocarbon from the product. The sulfur stream includes the sulfur from the product.
ADDITION SYSTEM FOR ADDING MATERIAL TO INDUSTRIAL PROCESSES
An addition system for introducing particulate material into an industrial process is disclosed. The addition system comprises a vessel for holding the particulate material, wherein the vessel has a top and a bottom; one or more weighing devices; a controller for controlling operation of the addition system; a base plate to support the vessel and optionally the controller; and three or more legs, each leg having an uppermost section that connects to the vessel and a foot that is connected to the base plate. The widest diameter of the vessel is less than the diameter of a circle drawn through the feet of the legs. The one or more weighing device are mounted on the base plate and support the legs of the vessel.
PRODUCTION SYSTEM AND METHOD FOR GENERATING HYDROGEN GAS AND CARBON PRODUCTS
A production system includes a first reaction chamber and a second reaction chamber. The first reaction chamber is configured to receive a first hydrocarbon stream therein through an input port and to form carbon seeds and hydrogen gas therein via hydrocarbon pyrolysis of the first hydrocarbon stream. The second reaction chamber includes a first input port and a second input port. The second reaction chamber is configured to receive the carbon seeds through the first input port and a second hydrocarbon stream through the second input port, and to form carbon product elements and additional hydrogen gas in the second reaction chamber via hydrocarbon pyrolysis of the second hydrocarbon stream. The carbon product elements represent the carbon seeds with additional carbon structure grown on the carbon seeds.
