Coal gasification phd thesis
The development of the subsequent gasification reaction model was based on two-phase theory of gases and solids consisting of the particle-lean bubble phase and the particle-rich emulsion phase which were distributed homogeneously when the gas velocity through the bed was in excess of the minimum fluidization velocity In this thesis, a new gasification concept is investigated, termed self-gasification, that overcomes, inter alia, the issue of heat integration. The concept entails an intermediate temperature (°C) and pressure ( bar) steam gasifier, where recycled ash components -contained in the biomass itself- serve as po-Author: Pavlina Nanou Coal gasification phd thesis Economic analysis revealed the system would be most competitive on an existing site with available feedstocks and steam. A longer reactor would increase time for homogeneous reactions to play a greater role

GASIFICATION FOR SYNTHESIS GAS PRODUCTION S ynthesis gas is one important intermediate to produce fuels for transportation and chemicals. Currently, synthesis gas is produced mainly from natural gas, coal or by-products from refineries. The usage of synthesis gas is about 50% to ammonia, 25% to hydrogen, and the rest is methanol The biomass gasification has been carried out using a fluidized bed gasifier. This work focuses on the production of syngas from biomass (rice husk). ASPEN PLUS simulator and pilot plant gasifier were used to investigate the effect of reactor temperature, equivalence ratio and steam to biomass ratio on composition of product gas Coal gasification phd thesis Economic analysis revealed the system would be most competitive on an existing site with available feedstocks and steam. A longer reactor would increase time for homogeneous reactions to play a greater role
