Resumo
The technology of a pulsed-detonation gun for gasification of organic waste with ultrasuperheated steam has been experimentally demonstrated for the first time. The experiments on autothermal natural gas conversion as well as on the allothermal gasification of liquid (waste machine oil) and solid (sawdust) wastes by the products of pulsed detonation of natural gas – oxygen mixture at a pulse frequency of Hz were conducted. At such a frequency, the time-averaged mean temperature and absolute pressure of detonation products in a flow reactor attached to the gun were about 1200 K and 0.1 MPa, respectively. The technology of the pulsed-detonation gun was shown to provide complete (100%) conversion of natural gas in fuel-rich natural gas – oxygen mixture into syngas containing H2 and CO with an H2/CO ratio of about 1.25. Gasification of liquid and solid wastes led to the production of syngas containing up to 80 and 65 %(vol.) (dry basis) reactive components (H2, CO, and CH4) with H2/CO ratios of 0.8 and 0.5, respectively. Comparison of syngas compositions obtained in experiments with fuel-rich natural gas – oxygen mixtures and in experiments with gasification of liquid and solid wastes under the same conditions at Hz and 0.1 MPa showed that these compositions almost did not depend on the feedstock type.
