Abstract:
1. A process for obtaining petrochemical products from a carbonaceous feedstock, said process comprising: pulverising a carbonaceous feedstock to obtain a pulverized feedstock having mesh size between 50-300; pyrolyzing the pulverized feedstock with syngas in a pyrolysis reactor at a temperature in the range of 700-1000° C. and a pressure in the range of 2-25 bar for 2-10 seconds to obtain pyrolysate comprising char, fluid petrochemical product, and at least a portion of the syngas; and gasifying the char with oxygen and steam at a temperature between 1200-1700° C. and pressure higher than the pyrolyzing pressure to obtain syngas having hydrogen content between 20-30 mole %.
