The present invention relates to a process for co-gasification of two or more carbonaceous feedstock, said process comprising combusting a first carbonaceous feedstock having high calorific value with low ash and high hydrogen content, to produce a heated effluent; carrying the heated effluent to second reactor where the heated effluent reacts with a second carbonaceous feedstock, having low calorific value with high ash and low hydrogen content, to produce synthesis gas.The present invention also relates to an apparatus for co-gasification of two or more carbonaceous feedstock, comprising a first reactor (), having a first feedstock inlet port (), a oxygen or air inlet port (), a steam inlet port (), a ash removal port (), and a solid recycle port (); a first cyclone separator () connected to the first reactor () through a first cyclone separator inlet port (); a second reactor (), having a second feedstock inlet port (), and a ash removal port (), the second reactor is connected to the first cyclone separator () through a gaseous inlet port (); and a second cyclone separator (), having a fine particles removal port (), and an effluent port (), wherein the second cyclone separator is connected to the second reactor through a second cyclone separator inlet port (). 1.
