A new process

natural gas & coal co-gasification for synthesis gas production

was developed by combining natural gas steam reforming and coal gasification process.The H2/CO ratio of crude synthesis gas could be controlled in the range of 1.0—2.0. Using a moving bed as reactor

coke and coal as the raw materials in the preliminary study of hot simulative experiments

the effects of blowing parameters H2O/CH4/O2 on the temperature in the flame zone and the H2/CO ratio of synthesis gas were investigated.Natural gas and oxygen were blown into the reactor at the same position to keep the temperature of reactor above 1000 ℃ and the blowing parameters H2O/CH4/O2 were adjusted to produce crude synthesis gas

in which the H2/CO ratio varied to the range of 1.0—2.0

the contents of active compounds (H2 and CO) were more than 90.0% and the residue methane was less than 2.0%.The concept of natural gas & coal co-gasification process is correct and feasible.
