Description
Technical field
The invention belongs to coal gasification and pyrolytic technique field, be specifically related to one and be capable of coal one step liquefaction, coal preparing natural gas multifunctional reactor.
Background technology
The energy is the basis of the national economic development, and the feature of China's energy resource structure is " rich coal, few gas, oil starvation ".At present, the petroleum reserves that China has been verified is 24,800,000,000 tons, gas reserves 4.4 trillion m3, and coal reserves is more than 1,000,000,000,000 tons.2011, the coal that China produces was 35.2 hundred million tons, crude oil 2.01 hundred million tons, natural gas 1011.15 hundred million m3, and consumption of coal accounts for more than the 70% of overall energy-consuming.From reserves data, coal, in China's energy consumption structure, will be occupied an leading position for a long time.From following China energy consumption structure trend, Coal Energy Source consumption proportion will reduce year by year, oil, natural gas consumption ratio will increase year by year, cause that oil supply external dependence degree can increase (within 2011, having reached 56.5%) year by year by modern coal liquifaction technology, coal is converted into various oil product and chemical products, is consistent with the Strategic Measure of China's energy consumption structure feature.
Predicting according to expert, present world oil yield is close to peak, it is contemplated that the year two thousand thirty is up to peak.During first time economic crisis, oil price is about 30 dollars/bbl, is about 70 dollars/bbl during second time economic crisis.Leaping high to 147 dollars/bbl during first time economic crisis, world petroleum price also can at run at high level from now on, and price is at least at 70～100 dollars/bbl, during to economic crisis next time, it is possible to leap high to 200 dollars/bbl.According to International Energy Agency it is expected that crude oil price every barrel rises 10 dollars, the speedup of China's GDP will reduce by 0.8%, price run up 0.8%.Morgan Stanley is thought, International Crude Oil (Brunt) every barrel rises 1 dollar, and the GDP growth of China will lose 0.06%.Calculating according to State Statistics Bureau, if crude oil every barrel goes up 10 dollars, if continuing 1 year, the impact on Consumer Prices index is 0.3%～0.4%.Greatly develop modern coal liquifaction industry, China's economic and the social development dependency degree to international petroleum can be alleviated, save a large amount of foreign exchange, increase the net export volume of China, promote that China's economic increases.
