Abstract
A syngas generator has at least pyrolysis unit and a cracking unit which recycles treated input therein. The pyrolysis unit may recycle treated char to provide input heat for feedstock. The cracking unit may recycle syngas to assist in treating input gas/vapor mixture.
Claims13
An improved syngas generating system comprising:
- a pyrolysis reactor having
- an inlet receiving input educt;
- a primary reactor with a conveyor moving input educt from an inlet towards a first end to an outlet towards a second end of the conveyor, said primary reactor heating the input educt to provide treated educt;
- and
- a return reactor receiving at least some treated educt from towards the second end of the conveyor and directing and heating the treated educt to the inlet of the primary reactor to provide a stream with the input educt;
- a char outlet removing at least some treated educt from the pyrolysis reactor as char;
- and
- a gas outlet, said gas outlet directing a gas/vapor mixture from the pyrolysis reactor;
- and a cracking reactor having
- an inlet receiving the gas/vapor mixture from the gas outlet of the pyrolysis reactor which is cracked to provide reaction products comprising syngas and recycled gas, with the recycled gas derived from the reaction products and remaining within the cracking reactor, and
- a recirculation stream propellant selected from the group of syngas, steam, gaseous combustible agent and inert gas assisting in directing the recycled gas remaining in the cracking reactor to mix with the gas/vapor mixture, and
- an outlet directing at least some syngas from the cracking reactor;
- wherein the cracking reactor treats the gas/vapor mixture with at least one of reaction products and recycled syngas derived from the reaction products to provide a stream cracked in a reaction chamber forming the syngas, the syngas directed from the outlet.
