Thermal processing overview

The purpose of this book is to review aromas that are developed by thermal processes. Because the flavor of heated foods is affected principally by aroma, we focus attention exclusively on the volatile flavor constituents of foods. Moreover, we intend this book to complement the 1986 book. Biogeneration of Aromas, ACS Symposium Series 317, edited by Thomas H. Parliment and Rodney Croteau. A broader overview of the Maillard reaction was discussed in the 1983 book, The Maillard Reaction in Foods and Nutrition, ACS Symposium Series 215, edited by George R. Waller and Milton S. Feather, which addressed the volatile, nonvolatile, and nutritional aspects of the Maillard reaction. [Pg.553]

D. Kress, Thermal Cracking of Used Oil to Produce Distillate Gasoil A Process Overview, Can. Chem. News, 52(2), 29-32, Feb. (2000). [Pg.635]

An overview of the fundamental early processes discussed in this section is summarized schematically in Figure 10. From this time onwards, thermal processes proceed. [Pg.140]

Having made this overview of the processes that occur in VRLA cells during charge, we can distinguish four groups of zonal processes that deserve to be discussed in more detail. These are (a) processes on the positive plates (b) processes on the negative plates (c) transport processes through the separator and (d) thermal processes in VRLAB. [Pg.579]

A major drawback of all the thermal processes of the day was the production of low valued coke. Alternative process routes were being developed to address this issue. One development pursued was hydrocracking which suppresses coke formation by the circulation of high pressure hydrogen. However, the route successfully pioneered by Houdry led to an eventual refinery configuration with the FCC centered as the primary means of conversion in today s modem refinery. Houdry s route appeared to preempt hydrocracking. Table I provides an overview of the major milestones of FCC (4, 5, 6, 7). [Pg.193]

Mixing Cell Calorimetry (MCC) The MCC provides information regarding the instantaneous temperature rise resulting from the mixing of two compounds. Together, DSC and MCC provide a reliable overview of the thermal events that may occur in the process. [Pg.2312]

Because the WAO process also aims to reduce sludge volume we will spend more time describing this process under the section dealing with Volume Reduction. The other thermal sludge conditioning method is best-known as sludge pasteurization, and deserves more than just a brief overview. [Pg.514]

Boron-containing nonoxide amorphous or crystalline advanced ceramics, including boron nitride (BN), boron carbide (B4C), boron carbonitride (B/C/N), and boron silicon carbonitride Si/B/C/N, can be prepared via the preceramic polymers route called the polymer-derived ceramics (PDCs) route, using convenient thermal and chemical processes. Because the preparation of BN has been the most in demand and widespread boron-based material during the past two decades, this chapter provides an overview of the conversion of boron- and nitrogen-containing polymers into advanced BN materials. [Pg.121]

All the above-mentioned methods will be discussed in this chapter. A number of filtration and reactor units that have been used in published work will be described and an overview of the different membrane materials will be given. As generally catalytic reactions deal with organic substrates and are usually carried out in an organic solvent, the membranes have to be solvent resistant. Thermal stability can also be an issue depending on the process conditions. [Pg.74]

The properties of thermally modified wood are highly dependent upon the thermal treatment employed, and it is very important to take these into account when comparing the various treatment methods employed. This chapter examines the effect of the process variables upon the properties of thermally modified wood, and then considers the chemistry of thermal modification. Studies of physical changes are discussed, followed by an overview of the biological properties of thermally modified wood. A short description of some recent literature on the use of thermal treatment combined with compression and on hot oil treatments is also included. [Pg.100]

An overview of the main reactions and processes is given in Table 1. Functionalization of lighter hydrocarbons to basic chemicals is performed by thermal activation, oxidation, sulfoxidation, ammoxidation, and chlorination. Reactions are carried out either in the gas phase or under milder conditions in the liquid phase. [Pg.14]
