“…Similar pattern of pyrolysis products distributions were observed by other researchers in which as pyrolysis temperature increased, the yield of char decreased, while the yield of bio-oil and gas increased but at a certain high temperature (around 500°C), the bio-oil yield start to decrease because secondary reaction takes place and more gases were produced [6,10,19]. Nevertheless, the maximum pyrolysis temperature for these RWS and MWS hardwood materials are relatively higher than most of agricultural plants such as paddy husk (maximum pyrolysis temperature was 450°C) and softwood trees such as spruce (maximum pyrolysis temperature was 500°C) reported in other literatures, conceivably due to greater biomass densities [8,13].…”

“…Based on the figure, CO and CO 2 are the major gas components in the NCG product. Some of the suggested ideas for the utilization of NCG are it could be recycled back into the pyrolysis reaction as a heat source or combusted to generate electricity [13,29]. More CO 2 was produced in pyrolysis of RWS while pyrolysis of MWS released higher CO content.…”

“…Most studies used biomass from agriculture crops, for example paddy husk [8,9], oil palm waste [10,11] and sugarcane bagasse [12], several on wood residues such as spruce [13] and birch [14], and from other waste materials including municipal waste [15] and rubber tires [16]. At the heart of a pyrolysis process is the reactor.…”

“…The classification is generally by heating rate and vapor residence time [6,18]. Initially, pyrolysis was done with slow heating rates (5-7 K/min) which mainly produced char [13,15]. In the last 25 years, pyrolysis at higher heating rates and very short vapor residence times has gained much attention as the process could increase bio-oil yield up to 50 wt.% [11,18].…”

Studies in Organic Archaeometry VII ‐ Differentiation of Wood and Bark Pitches by Pyrolysis Capillary Gas Chromatography (PY‐CGC)

Tars and pitches were prepared from wood and bark of various deciduous trees and conifers and analysed with the intention to distinguish between various starting materials. All this was done before the background of an archaeometrical problem: to provide a basis for the chemical identification of those pitches which are frequently found in archaeological excavations.Intending to extend the already existing possibilities for such analyses the present paper is dealing with the application of pyrolysis coupled with capillary gas chromatography and by subsequent chemometric studies. It could be shown that by this technique indeed not only tars and pitches prepared from deciduous trees and from conifers could clearly be differentiated, but that even respective species could be identified. Thus a fundament is provided for future studies aiming to identify the starting material of real archaeological finds by a novel method which requires by far less quantities of sample material as compared to the methods hitherto used by us.

Analytical pyrolysis is a powerful technique that is seldom used in the pulp and paper industry. This article illustrates the utility of the technique to study the chemistry of wood and pulps, mechanistic aspects of pulping, troubleshooting process upsets in pulp and papermaking, and evaluating the quality of finished products. The technique has advantages over other analytical techniques in that little sample preparation is required and enough data can be obtained from very small amounts such as dirt spots on paper. In many cases good data can be obtained by analyzing the pyrolysis products by gas chromatography (GC) with flame ionization detection (FID). Detection with mass spectrometry (MS) offers the advantage of absolute qualitative and quantitative determination of the chemistry of the analytes. In many instances the chromatography can be improved by on‐line derivatization of the pyrolysis products with an alkylating agent. This article takes the reader through a survey of the different types of analytical pyrolysis systems, through data analysis and processing, and examples of applications of analytical pyrolysis in the pulp and paper industry. Ample illustrations are used to highlight the usefulness of the technique.
