METHOD FOR DECOMPOSITION OF HYDROCARBONS AND DEVICE FOR ITS EMBODIMENT

摘要

FIELD: decomposition of hydrocarbons. SUBSTANCE: method for decomposition of hydrocarbons to produce hydrogen and carbon black includes passing of the feed initial flow stock through the plasma torch where it undergoes pyrolytic decomposition. Feed initial stock flow is transported through he plasma torch and subjected to the first heating in the zone located in the immediate vicinity of plasma flame. In the zone directly below the plasma flame, mixing of hydrocarbon material and plasma gas is effected and the temperature increases to that of the stock material decomposition. In this zone, free hydrogen is obtained and dehydrated carbon material in form of liquid drops. The material produced passes one or more successive zones where full decomposition of hydrocarbons takes place to carbon black and hydrogen. In this zone, additional stock material may be added to cause cooling and reaction with produced carbon black. This provides for growing of particle sizes, density and produced quantities without additional energy source. Then produced product is discharged and separated and to increase the energy yield hot gases may be transported through returning pipe to the torch. EFFECT: higher efficiency.
