At present, there are more than 70 manufacturers of benzene, total annual production capacity of about 1.9 million tons, which accounts for about 80 percent benzene oil, accounting for about 20% of coking benzene. Petroleum benzene plant mostly in China Petrochemical Corporation and China National Petroleum Corporation purchases benzene, benzene coking plant mainly in metallurgical systems. Annual production capacity of 10,000 tons or more than 20 manufacturers demand benzene, benzene demand accounts for about 85 percent of the world's total production capacity of 36 million t in 2004 will grow to 43 million in 2009 t. From 2004 to 2009 the average annual growth rate of demand of 3.6% from 1999 to 2004 with the same growth rate. Benzene market grew steadily in 2004, 50% of benzene for the production of ethylbenzene and styrene monomer, 18% for the production of cumene, 12% for the production of cyclohexane, 7% for the production of nitrobenzene . According to the analysis of chemical benzene, ethylbenzene and styrene monomer in 2009 will once again accounted for the amount of 54% of the world Benzene Benzene, for cumene will rise to 18.5%, for cyclohexane will drop to 11.5% for nitrobenzene will rise to 7.5 percent, one of the fastest-growing part of the benzene amount of aniline (nitrobenzene is its precursor), its average annual growth rate of about 5.5% to 6%.
