The MTO reaction on a calcined SAPO-34 with a unit cell composition of (Si2.88Ali8Pi5.12)072, supplied by SINTEF Materials Chemistry, Norway, has been investigated (90). The catalyst particles (52-140 mesh) were dried at 773 K for more than 3 h. Quartz particles (52-140 mesh) were placed between the quartz wool and the catalyst particles (Fig. 1) to minimize temperature gradients and improve the distribution of the flowing gas in the catalyst bed.

Aluminum, boron, carbon, iron, nitrogen, oxygen, phosphorus, sulfur and titanium are the common impurities in the SoG-Si feedstock. Arsenic and antimony are frequently used as doping agents. Transition metals (Co, Cu, Cr, Fe, Mn, Mo, Ni, V, W, and Zr), alkali and alkali-earth impurities (Li, Mg, and Na), as well as Bi, Ga, Ge, In, Pb, Sn, Te, and Zn may appear in the SoG-Si feedstock. A thermochemical database that covers these elements has recently been developed at SINTEF Materials and Chemistry, which has been designed for use within the composition space associated with the SoG-Si materials. All the binary and several critical ternary subsystems have been assessed and calculated results have been validated with the reliable experimental data in the literature. The database can be regarded as the state-of-art equilibrium relations in the Si-based multicomponent system.
