Abstract:
1. A system for the gasification of a carbonaceous material, comprising: a. a reactor for the gasification of a solid stream comprising particulate carbonaceous feedstock to produce heat and a mixture product comprising synthesis gas and char; b. an initial separating device for separating said mixture product of part a) to create a gaseous product stream and a first solid product stream comprising char; c. a coarse particulate fluxing agent having an average size in the range from 5 microns and 30 microns; d. an entry point for the addition of a coarse particulate fluxing agent downstream from the initial separating device of part (b); e. a particle filtration unit comprising a plurality of filter elements for filtering the gaseous product stream of part (b) and the coarse particulate fluxing agent of part (c) to retain residual particles of char, thereby creating a second solid product stream while allowing passage of said gaseous product stream of part (b), wherein the coarse particle fluxing agent decreases the permeability of the filter elements to entrained char from part (b), while maintaining permeability of synthesis gas, wherein the pluralit of filter elements are configured to allow passage of char particles and retain the coarse particulate fluxing agent; f. piping for conducting the first and second solid streams, having:
