THE TWO-STAGE PROCESS OF THERMOCHEMICAL PROCESSING OF LIGNIN IN A FIXED BED. 1. TECHNOLOGICAL SCHEME OF THE INSTALLATION. METHODS FOR CALCULATING PYROLYSIS GAS COMPOSITION

A method is proposed for the thermochemical processing of biomass (lignin) meant for the use of one reactor for the production of two synthetic gases dissimilar in composition and calorifi c value: low-calorie (1800–2000 kcal/nm³ ) and medium-calorie (~4000 kcal/nm³ ) with a low resin content. Two methods for calculating the composition of pyrolysis gas have been developed. Various variants of the operation of installation in cyclic and quasi-stationary modes are considered, taking into account unique technical solutions for supplying coke–ash residue from the pyrolyzer to the gasifi er
