Kinetic models for biomass pyrolysis
Biomass is a versatile material. It can be directly combusted to produce heat; however, by first subjecting it to a thermal or biological degradation, it can also be converted to products with a higher heating value or to materials with properties superior to those of the raw material [1]. When heated in the absence of oxygen, biomass decomposes into a range of products; including char (solid),...
متن کاملEstimation of Kinetic Parameters of Coking Reaction Rate in Pyrolysis of Naphtha
The run length of cracking furnaces is limited by the formation of coke on the internal skin of the reactor tubes. The reaction mechanism of thermal cracking of hydrocarbons is generally accepted as free-radical chain reactions. On the basis of the plant output data and the insight in the mechanisms for coke formation in pyrolysis reactors, a kinetic model describing the coke formation has been...
متن کاملUncertainty-quantifying models for chemical-kinetic rates
In this study, strategies are proposed for modeling the input uncertainties in combustion calculations under chemical-rate uncertainties using as an example hydrogen-oxygen kinetics. For this purpose, this report is divided into the following sections. In Section 2, an assessment is made to ascertain the limitations of state-of-the-art treatments of experimentally-derived chemical-kinetic uncer...
متن کاملRemoval of Metribuzin Herbicide from Aqueous Solution Using Corn Cob
Agricultural solid waste (corn cob) has been investigated asbiosorbent for removal of metribuzin herbicide from aqueous solution. Parameters influencing extraction efficiency such as pH of the sample, contact time of sample with biosorbent, shaking time, temperature, heating time, sorbent dose were studied. Maximum sorption of metribuzinwas found at pH 5.0. The sorption of metribuzin on corn co...
متن کاملDetailed chemical kinetic reaction mechanism for biodiesel components
New chemical kinetic reaction mechanisms are developed for two of the five major components of biodiesel fuel, methyl stearate and methyl oleate. The mechanisms are produced using existing reaction classes and rules for reaction rates, with additional reaction classes to describe other reactions unique to methyl ester species. Mechanism capabilities were examined by computing fuel/air autoignit...
