Gasification of plastics and solid fossil fuels to produce organic compounds

A process for the production of syngas comprising:

• a. charging an oxidant and a feedstock slurry composition to a gasification zone within a gasifier without pressurizing the feedstock stream in a lock hopper prior entry into the gasifier, said feedstock slurry composition having a viscosity in the range of 5357 cP to less than 30,000 cP and comprising a solid fossil fuel and comprising plastics wherein 90 wt. % of the plastics have a particle size in the largest dimension of not more than 2 mm;
• b. gasifying the feedstock slurry composition together with the oxidant in a gasification zone to produce a syngas composition;
• and
• c. discharging at least a portion of the syngas composition from the gasifier;
• and producing an organic compound from said syngas composition.

A process for the production of syngas comprising:

• a. charging an oxidant and a feedstock slurry composition to a gasification zone within a gasifier without pressurizing the feedstock stream in a lock hopper prior entry into the gasifier, said feedstock slurry composition comprising solids and liquids and having a viscosity in the range of 5357 cP to less than 30,000 cP, said solids comprising plastics and a solid fossil fuel, wherein (i) the plastics are present in an amount up to 25 wt. % based on the weight of the solids in the feedstock slurry and (ii) 90 wt. % of the plastics have a particle size in the largest dimension of not more than 2 mm, and said liquids comprising water;
• b. gasifying the feedstock composition together with the oxidant in a gasification zone to produce a syngas composition;
• and
• c. discharging at least a portion of the syngas composition from the gasifier, and producing an organic compound from said syngas composition
• wherein at least one of the following conditions is present:
• (i) gasification within the gasification zone is conducted at a temperature of at least 1000° C., or
• (ii) the pressure within the gasification zone greater than 2.7 MPa, or
• (iii) no steam is introduced to the gasifier that flows into the gasification zone, or
• (iv) the tar yield is less than 4 wt. %, or
• (v) the gasifier contains no membrane wall in the gasification zone, or
• (vi) a combination of two or more of the above conditions.
