The ohjcct is thc production of synthetic liquid fucl hy the renction of cxrbon iiionositlc i i n d liydrogcn a t iitinosplieric pressure in tlic prcsciicc of cntiilysts, siicli as nickel.
Onc of the iiiiiin fciiturcs of tlie proccss is that t,hc ciitiilyst, is supported in ti frninework of silicn, obtninctl hy tlic iisc of crisily tlccoiiiposiiI~lc silicic acid estcrs, sricli ris ethyl ort,lio-silicntc, which nrc patcnted products iiiatle hy Alhriglit k \'ilson, [Jttl. of Biriiiinglinni.
