The invention relates to a reactor comprising a moving bed of solid particles that move in the direction of gravitation, and to a method for heating a reactor that comprises a moving bed, for the purpose of pyrolysis reactions.

A reactor has a reactor vessel and a reaction tube. Tube sections of the reaction tube run inside the reactor vessel. The tube sections are each electrically connectable to a current connection in a current feed region. Current feed arrangements are arranged in the current feed region to which in each case one or one group of the tube sections is electrically connected. Each current feed arrangement has a first and a second section, the first section extending along a longitudinal axis starting from the respective or group of tube section(s). The first section at least partially surrounds the second section or the second section surrounds the first section in a sleeve-like manner. The first and second sections each have contact surfaces arranged obliquely to the longitudinal axis. The current feed arrangements each extend through a wall of the reactor vessel.

The present disclosure is directed to systems and methods for direct electrical heating of process heaters tubes (e.g., reactor tubes) using galvanic isolation techniques. The disclosure is also directed to systems and methods for direct electrical heating of process heaters tubes wherein the tubes are galvanically isolated in such a manner as to avoid the use of electrical insulation of the tube from the rest of the system, such as the other tubes, the tube inlet header and/or the tube outlet header, and the reactor shell.

Methods of heating a reactor system by providing electrical energy are described. A reactor system comprising at least one reactor tube having a catalyst disposed therein and comprises at least one electrically conductive surface is heated by providing electrical energy to the at least one electrically conductive surface on the reactor tube and adjusting a current level of the electrical energy provided to the at least one electrically conductive surface to control the temperature of the reactor tube and the catalyst disposed therein. The reactor tube may be electrically isolated from other electrically conductive components of the reactor system.

A continuous process includes supplying, to a hydrogen production unit, an energy source in the form of mechanical energy or electrical energy produced from thermal energy generated in a hydrogenation process in a hydrogenation reactor unit, and flowing a light hydrocarbon feed stream into the hydrogen production unit in the presence of a catalyst to produce a hydrogen gas enriched stream using the energy source.

The present disclosure provides a system comprising a reactor, a medium temperature heating section and a superheating section. The reactor comprises a moving packed bed of catalytic particles and a feed gas interacting with the catalytic particles.

The medium temperature heating section is configured to heat at least one of gases or catalytic particles to a first defined temperature, and the superheating section is configured to heat the at least one of gases or catalytic particles received from the medium temperature heating section with an electrical system and to provide the at least one of gases or catalytic particles heated to the reactor.
