Chemical reactor design, it requires knowledge of the chemical kinetics (Chemical Kinetic), which is a calculation of the speed of the reaction by the study of reactions, energy boost, the procedure determines the reaction, reaction mechanisms, including education, factors that affect the speed of reaction. For example, the indicator of the importance of speed of reaction: the reaction of combustion reactions, combustion in General, which actually means to react with oxygen, 7. Generally occur, but that very slowly until we could notice a change. But when we do, the heat will cause the reaction to occur rapidly and heat out, acting as the cause a reaction occurs continuously until all of the precursor to the factors that affect chemical reaction is as follows: 1. the nature of the precursor and product. 2. the concentration of precursor and product. 3. ambient temperature 4. the influence of external substances such as catalytic (Catalysts) or inhibit the reaction (Inhibitors) The type of chemical reaction is divided into two categories.1. the quantity of the substance, according to the number of relationships breakdown) (Single and Multiple Reaction Reaction). The relationship of the mass, the substance of the elements related to the reactions that can be written with a single substance, quantity, relation, only the equation an equation called the single reaction (Single Reaction) If you want to use multiple equations are called the reaction that the plurinational reactions (Multiple Reaction). 2.), broken down by sector of the relevant reaction wat (Homogeneous and Heterogeneous Reaction). Wat region of the react will determine whether a reaction is? If the reaction occurred in the same region, called wat reactions, Ph.d. (Homogeneous Reaction), but if there are more than 2 or more sectors, called wat vividhkarn reaction (Heterogeneous Reaction).In chemical kinetics, that education may have some reactions can be reversed (Reversible Reaction), which is a Reversible Reaction occur when the balance point (equilibrium), the Forward Reaction is equal to the Backward Reaction and properties of all types in which the substances are to be in equilibrium, the closed system (Closed System), which is the Driving Force in the birth, there are 3 reasons: equilibrium. 1.) Pressure 2.) Concentration 3.) Temperature The trial of the Kinetic Parameter Estimation in the case of non-constant Temperature (Nonisothermal) using Gravimetic Thermal Analyser (TGA) machine, which is a tool for analysis of chemical reaction of chonnasat Parameter based on the reduction of the weight of the cardboard. That depends on the temperature of this time have been used to study the behavior of solids, such as combustion, membranes rose Lai of biomass, the crack of solid, etc.
