Endogenerators

The operation concept is based on a low-temperature conversion of a hydrocarbon air mixture using a proprietary catalyst at 950°C. Gas atmosphere compositions produced from different hydrocarbon gases are given in Table 2. The catalyst is heated by electric heaters.

Designation:

LCE – Low-temperature conversion, endogas

Endogenerator LCE - 10

Main design features of the LCE series generators are as follows:

platinoid catalyst on a highly porous carrier.
low conversion temperature

oxygen probes used in dew point control

Advantages of the LCE series generators:

easy servicing
high service durability of the retort, heaters and catalyst due to the low conversion temperature (950°C).
quick through heating-up of the catalyst and uniform temperature distribution within the reaction zone prevent carbon formation.
high regenerative capacity of the catalyst after local burning down: the catalyst carrier remains damage-proof up to 1,500ºС (given the fact that the working temperature in the generator is 950°C)
two cooler heat exchangers, of air and water type, are used to decrease water consumption for cooling endogas.
high quality of endogas is determined by practically total absence of methane and water steam.
high reliability of the automatic system for endogas composition control is related to an oxygen sensor feeding a signal to be processed by a special sequence controller with a dew point temperature indicator, rather than a humidity sensor.
almost 100 % of reliable constituent components are produced by leading European companies
