Abstract

Nongaseous carbonaceous material is heated by a method comprising introducing tangentially a first stream containing a nongaseous carbonaceous material and carbon monoxide into a reaction zone; simultaneously and separately introducing a second stream containing oxygen into the reaction zone such that the oxygen enters the reaction zone away from the wall thereof and reacts with the first stream thereby producing a gaseous product and heating the nongaseous carbonaceous material; forming an outer spiralling vortex within the reaction zone to cause substantial separation of gases, including the gaseous product, from the nongaseous carbonaceous material; removing a third stream from the reaction zone containing the gaseous product which is substantially free of the nongaseous carbonaceous material before a major portion of the gaseous product can react with the nongaseous carbonaceous material; and removing a fourth stream containing the nongaseous carbonaceous material from the reaction zone.

Dependent claims

A process for heating nongaseous carbonaceous material comprising:

a. introducing tangentially a first stream containing a nongaseous carbonaceous material and carbon monoxide into a reactor structure comprising:
i. a reactor having a covered cylindrical chamber,
ii. a conical portion attached to said covered cylindrical chamber opposite the covered end thereof and in communication therewith,
iii. a first inlet means for directing a first stream containing a nongaseous carbonaceous material tangentially into said covered cylindrical chamber and for causing nongaseous material to form an outer spiralling vortex which is urged towards said conical portion and for causing nongaseous material to be substantially separated from gases,
iv. a second inlet means for simultaneously and separately introducing a second stream containing gaseous oxygen into said reactor away from the walls thereof, said second inlet means communicating with said reactor at a point removed from the covered end thereof,
v. a first outlet means located in the covered end of said covered cylindrical chamber, and oriented along the axis thereof and in communication therewith, for removing gases substantially separated from nongaseous material, and for forming an inner spiralling gaseous vortex, and
vi. a second outlet means located at the smaller diameter end of said conical portion and in communication therewith for removing nongaseous material;
b. forming an outer spiralling vortex within said reactor to cause substantial separation of gases from said nongaseous carbonaceous material;
c. simultaneously and separately introducing a second stream containing oxygen into said reactor through said second inlet means and internally of said outer spiralling vortex, and reacting said oxygen with said first stream thereby producing a gaseous product comprising carbon dioxide and producing a heated nongaseous carbonaceous material;
d. removing a third stream from said reactor, through said first outlet means, containing said gaseous product which is substantially free of said nongaseous carbonaceous material before a major portion of said gaseous product comprising carbon dioxide can react with said nongaseous carbonaceous material;
and
e. removing a fourth stream containing said heated nongaseous carbonaceous material which is a major portion of said nongaseous carbonaceous material introduced in step (a) from said reaction zone through said second outlet means.
