BC Bugwood Envirochem Services Inc. 4.6 Bugwood to Methanol 4.6.1 Methanol Production through Gasification of Bugwood The conversion of biomass to methanol requires numerous processes some of which are only necessary depending on the choices upstream (see Figure 4.6.1). The two main steps which can not be avoided and which constitute the key parts of the process are the gasification and methanol synthesis. The first step, gasification is the transformation of the feedstock to syngas. The correct choice of gasification will minimize the subsequent cleaning steps that will be necessary for the utilization of the syngas for methanol production. The second step methanol synthesis involves the transformation of the syngas to methanol. All the processes are complex and use many pieces of specialized equipment which makes the operation expensive and places emphasis on the importance for optimization of the process as a whole. The choice of gasifier is dependant on many parameters with the major one being size of operation. Different sized operations suite different transportation and gasification method which ultimately give the net efficiency. Gasification Gas Cleaning Methanol Although methanol production is technically challenging, feedstock requirements for production of methanol from thinnings are minimal. Most analysis assumes the process from bugwood to methanol requires the feedstock to be debarked, but this assumption may be considered conservative. The debarking of feedstock in other processes like pelletization, bio-oil and syngas have end uses that are incompatible with contaminants that may be produced from including the bark. For methanol, the chemical composition of the bark does not impact the final product the same way as it does for other processes; unlike most studies this analysis assumes that debarking is not required. The first three pre-processing steps best suited to roadside processing are shown in Figure 4.6.2 below. The energy used for these steps is usually in the form of diesel at location or electricity if done at the plant. For our study, we will make use of the end product (methanol) for these processes. Figure 4.6.2 Pre-processing Flow Diagram Entrained flow gasifiers require more pre-processing than fixed bed and fluidized bed gasifiers. This is because entrained flow gasifiers require the feedstock be pulverised into fine powder. Entrained feedstock must be 100 to 600 μm compared to the 3000 μm needed for fast pyrolysis. This is accomplished by either grinding or using torrefaction and then grinding. Torrefaction is a thermochemical pre-treatment carried out at a temperature of 200°C to 300°C in the absence of oxygen (see Figure 4.6.3).
