Electrically heated reactor and process for gas conversions using reactor

Abstract

The present invention relates to a reactor configuration comprising at least one electrically heated furnace which defines a space, with at least one reactor tube placed within the furnace space and said reactor tube having an exit and entrance outside of the reactor furnace, and wherein said furnace is further provided with at least one electrical radiative heating element suitable for heating tohigh temperatures in the range of 400 to 1400 DEG C, the heating element being located inside said furnace in such a way that the heating element is in no direct contact with the at least one reactortube; and; and a number of inspection ports in the furnace wall such to be able to visually inspect the condition of the at least one reactor tube on each opposite side of said reactor tube during operation, the total number of inspection ports being sufficient to inspect all reactor tubes present in the furnace at their full length and circumference; and wherein the heating duty of the furnace is at least 3 MW. The process being electrically heated demands a heat- flux and temperature profile. In many applications the heat-flux is larger when the process enters the furnace whilst having a lower temperature. Towards the exit the heat-flux is lower whilst having higher temperature. The present invention can accommodate the requirement. The reactor is useful in many industrial scale high temperature gas conversion and heating technologies.

Description

technical field [0001] The present invention relates to a reactor configuration comprising at least one electrically heated furnace and to a method for performing a gas conversion process at high temperature comprising introducing at least one gaseous reactant into said reactor configuration in type. The reactor and method described can be used in many high temperature gas conversion and heating technologies on an industrial scale. Background technique [0002] The issue of global warming and the need to reduce the world's carbon footprint are currently high on the political agenda. In fact, addressing global warming is considered the most important challenge facing humanity in the 21st century. The Earth system's capacity to absorb greenhouse gas emissions has been exhausted, and current emissions must be completely halted by about 2070 under the Paris climate agreement. To achieve these reductions requires at least serious industrial restructuring away from producing CO...
