Chemicals and materials from coal in the 21st century

Coal may become more important both as an energy source and as the source of organic chemical feedstock in the 21st century. The demonstrated coal reserves in the world are enough for consumption for over 215 years at the 1998 level, while the known oil reserves are only about 39 times of the world's consumption level in 1998 and the known natural gas reserves are about 63 times of the world's consumption level in 1998. Coal has several positive attributes when considered as a feedstock for aromatic chemicals, specialty chemicals, and carbon-based materials. Substantial progress in advanced polymer materials, incorporating aromatic and polyaromatic units in their main chains, has created new opportunities for developing value-added or specialty organic chemicals from coal and tars from coal carbonization for coke making. The decline of the coal tar industry diminishes traditional sources of these chemicals. The new coal chemistry for chemicals and materials from coal may involve direct and indirect coal conversion strategies as well as the co-production approach. Needs for environmental-protection applications have also expanded market demand for carbon materials. Current status and future directions are discussed in this review.

ChemInform Abstract: Design of Reaction Systems for Specialty Organic Chemicals

Abstract Design of reaction systems for specialty organic chemicals requires utilization of chemical reaction engineering principles for a wide variety of kinetic problems. Kinetic analysis must include breakdown of the overall reaction into definable components in order to identify parallel and/or consecutive reactions that result in by-product formation. Once identified, methods of minimizing by-product formation can be developed. Examples are described of complex reaction systems which have required development of specialized procedures to minimize by-product formation. Each example represents a different kinetic problem and method of solution. Emphasis is placed on the close interaction between chemists and chemical engineers during laboratory development and plant reaction system design to achieve successful commercial operation.

Study paints grim picture for U.K. chemicals

A sober, if gloomy, prospect faces the chemical industry in the U.K. 'There is strong evidence that the industry will decline significantly by 1990, maintains Gareth H. Thomas of the London-based National Economic Development Office. I hope very much that somebody can convince me that this analysis is wrong because the implications are serious. Speaking at a recent meeting of the Society of Chemical Industry in London, Thomas presented the salient points of a major study on the near-term prospects for the industry. The study, to be published soon, is a followup on one made two years ago by the chemicals committee of the National Economic Development Council (NEDC). This latest NEDC study centers on nine main branches of the industry—agrochemicals, dyes and pigments, fertilizers, inorganics, paints, petrochemicals, pharmaceuticals, soaps and detergents, and specialty organic chemicals. Those facing the prospect of serious decline are fertilizers, inorganics, and petrochemicals. Four—agrochemicals, dyes ...
