A feeding system for feeding an inlet material to a process system, comprising a pressure force unit, upstream of a flow force unit, configured to increase a pressure of an inlet material flow; and an upstream control valve configured to subject the inlet material flow to a pressure-drop; a control unit configured to control a start-up of the feeding system by: circulating the inlet material flow in a circulation loop, while a valve system is arranged in the first position; increase the pressure of the inlet material flow; subject the inlet material flow to a first pressure-drop: when the inlet material flow is circulating, arrange the valve system in the second position; subject the inlet material flow to a second pressure-drop, wherein the first pres-sure-drop is greater than the second pressure-drop.

A piston having a chamber and a barrel disposed in and that may translocate within the chamber. The barrel includes a terminal end having a seal, and the seal has an annular ring having a first wall and a second wall, the second wall is orthogonal to and extends from the first wall such that a first portion of the first wall protrudes away from the second wall in a first direction and a second portion of the first wall protrudes away from the second wall in a second direction that is substantially opposite to the first direction.

A standalone precursor is for synthesizing nanomaterials such as boron nitride nanotubes. The standalone precursor includes a pillar. Pores and through-holes are defined in the pillar. Each of the through-holes extends continuously from a first opening on an outer surface of the standalone precursor to a second opening on the outer surface of the standalone precursor. The first opening is diametrically opposite to the second opening across the standalone precursor.

A method for controlling a synthesis loop for production of a chemical product, such as ammonia or methanol, wherein a feed rate of the loop depends on at least one source of renewable energy, the pressure of the loop and the delivery rate of a makeup compressor and of a circulation compressor are continuously controlled to follow the variable rate of the feed while maintaining the loop pressure within a target deviation from a design loop pressure.

A reactor for coating particles includes one or more motors, a rotary vacuum chamber configured to hold particles to be coated, wherein the rotary vacuum chamber is coupled to the motors, a controller configured to cause the motors to rotate the rotary vacuum chamber about an axial axis of the rotary vacuum chamber such that the particles undergo tumbling agitation, a vacuum port to exhaust gas from the rotary vacuum chamber, a paddle assembly including a rotatable drive shaft extending through the rotary vacuum chamber and coupled to the motors and at least one paddle extending radially from the drive shaft, such that rotation of the drive shaft by the motors orbits the paddle about the drive shaft in a second direction, and a chemical delivery system including a gas outlet on the paddle configured inject process gas into the particles.

The current invention relates to a method for producing CO from CO2, comprising the steps of: providing process gas comprising CO2, and optionally CO, to a plasma jet generator; igniting a plasma in the process gas by the plasma jet generator, thereby obtaining a plasma jet comprising CO and O species; introducing the plasma jet into a carbon reaction chamber; extracting product gas from the reaction chamber, said product gas comprising said CO and CO2 and recycling at least part of the product gas and providing said product gas comprising CO and CO2 to a plasma jet generator. The invention also relates to a system for converting CO2 to CO, comprising: a carbon reaction chamber and a plasma jet generator, wherein said gas outlet of the reaction chamber is in fluid communication with the process gas inlet of a plasma jet generator.
