1. 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 a solid fossil fuel and plastics, and said plastics are present in an amount up to 25 wt. % based on the weights of solids in the feedstock composition, and said liquids comprising water;
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.
