can be used to produce a syngas with the proper H2 to CO ratio. Coal gasification, followed by the water shift reaction, is used worldwide to produce syngas which is then converted downstream to methanol. Coal gasification has become a major syngas production process for the manufacture of methanol in China, which has more than 50 such plants in operation, with dozens more in construction or planning. Even more plants are in operation, with dozens more in construction and planning (in China and Mongolia), using the methanol to produce valuable downstream products. These coal gasification plants producing methanol, as well as the integrated Methanol-to-Olefins (MTO) and Methanol-to-Propylene (MTP) plants, have allowed China and Mongolia to economically produce a wide range of downstream products, replacing expensive or scarce natural gas and petroleum-based feedstocks.

Determining an optimum catalyst for liquidphase dehydration of methanol to dimethyl ether [J].

A copper catalyst appears to be only slightly active at temperatures below 230 oC, and accelerated re-crystallization of the copper must be expected at temperatures exceeding 270 oC, there is only little tolerance in selecting the most favourable reaction temperature. Rising pressures favours CO and CO2 conversions: however, costs for equipment in the synthesis loop and syngas compressor move in opposite directions on the pressure in the synthesis reaction.

In general practice, un-reacted gas from the methanol synthesis reactor is recycled back to the reactor, thereby acting as a syngas quench cooler. The recycle ratio (recycle gas : syngas feed gas) is 3 : 1 up to 7 : 1 in normal practice.

Dimethyl ether synthesis from syngas derived from biomass gasification and reforming [J].

Methanol is produced from synthesis gas (carbon monoxide and hydrogen), itself derived from oil,coal or, increasingly, biomass. It may become central to the development of biorefineries as an intermediate in the conversion of biomass to useful products.

Whereas a few years ago, only a small amount of methanol was used directly as a fuel in cars, this use is now increasing rapidly. In China petrol is mixed with methanol (15%) without the need for engines to be redesigned. With some redesigning, more methanol (up to 85%) can be used. The advantage for China is that the methanol can be produced from both coal and biomass via synthesis gas. This emphasis of using methanol as a fuel is reflected in the global production figures for methanol. Thus worldwide, use of methanol as a fuel now accounts for 10% (about 7 million tonnes a year) but is expected to increase in the coming years.
