ations does not often appear in the catalytic literature, so the article by T.J. Lawton (p. 178) is especially welcome. He describes Johnson Matthey's Honeycat air pollution control system and demonstrates its superiority to thermal incineration. He does not, perhaps understandably, say much about either the ceramic honeycomb support or the platinum group metals used on it. In one application in the printing industry the thermal energy from catalytic incineration provides at least 5056 of the background heat for the factory.
The control of motor vehicle emissions is a much more prominent subject in the literature. M.P. Walsh, a US. consultant and former Deputy Assistant Administrator in the U.S. Environmental Protection Agency, gives (p. 194) a detailed assessment of the implications of the control of motor vehicle emissions for climate modification. He argues that the latest catalyst technology must be applied worldwide, without delay, to prevent further major damage to the environment. One might think in a parochial way that the argument sounds like good news for those of us in the catalyst business but the article is a sober and indeed sobering account of the complex interplay of the many factors, very welcome as a contrast to so much of the journalism on the subject. He concludes:"... the dual goals of low emissions of carbon monoxide, hydrocarbons and nitrogen oxides, and improved energy efficiency (and therefore lower carbon dioxide) are not only compatible but are mutually reinforcing. However, significant gains in either area are dependent on forceful government requirements. Mandatory fuel efficiency standards throughout the world are feasible and necessary to slow the growth in carbon dioxide emissions. In conjunction with stringent carbon monoxide, hydrocarbons
